DIY Speakers

[Donnie27]

To keep from messing up the Sub thread. I started this one.

Wood & Size;

They will measure 48" Tall, 13.5" Wide and 18" Deep and ported. I'll use 3/4" Birch and I will use screws and Glue. I want to do Gloss Transparent Black with a Grey Grill cloth. They'll be far too heavy for the extra braces necessary for Glue only. I now might to use a baffle since I bought a bigger sub than I planned on using. I still need Veneer birch strips. See below? Might Veneer the whole thing.

I placed the Sub so that if I still want to do two 4 ohm 10" subs, all I have to is cut out the second whole.

I first planned on two 10" woofers but after tests, the two Dayton 10" classics couldn't hang. The only other thing I like was the Hi-Fi/Swann 10" but it was too expensive for 2. The Titanic and others were out of the Budget as well. Sure they're Car woofers DVC so I'll do them Parallel for 8ohm instead 4 each or series 2 ohm.

I got my Cross overs, a pair of Cerwin Vega 600W Jobbies that might not ever see 100W LOL!

Of course, the ports, tweeters, cross-overs and grill Cloth.

Planar tweeters, what can I say:)

The Mid Range Drivers are giant and tips the scales at 5 Lbs. LOL! Here's pic compared to a DVD Disc. I might have go back and use a Soft Dome tweeter, not crazy about Paper Cone Midrange thought.

You can see the Birch sticker on the boards. Will add more stuff later. These speakers are planned to take the place of the Infinity SM 120 in my computer room. The Harmon Kardon only serves as an Amp for my Computer. The I-SM120's are great for Games, blends well with the other speakers and Sub, no matter what the Audiophile wanna be's say. I love Music in Stereo via digital out. The Infinity's are only so so without the Sub.

[Donnie27]

Well, the only hold up now is my Sub. The jerks at Techronics:down: have me in limbo where I can't cancel their order until they finalize the sale.:mad:

I'm also stuck between 5.25" Midrange cone speakers or Midrange Horns. The horns are huge and the 6 X 5 Horn Lens makes it even more imposing. I would be ready to do some major work this weekend if it weren't for the Woofer delays.

[Donnie27]

After two days of wasting my time, they tell me today they no longer sell that model and try to sell me the newer model. Order canceled. I'm now getting the "Pioneer Premier TS-W1007D4" for the same price Techronics wanted for the newer lesser Subs and I'm getting free shipping while the other jerks wanted $30 shipping. These speakers still might end up with four Woofers (two in each enclosure) instead of one Sub. Again, during 5.1 they're useless, this is merely for the 2 channel stuff.

My midrange speakers are due on the 28th and the Woofers on the 30th. Screw Techronics for slowing me down:mad: I still need to run the Cone vs Horn Mid Range. Those Planar tweeters were well worth it's $84. Once I figure out which one I'll use, I'll cut the final hole.

[Miwo]

Cool, looks like your project is coming along nicely.

Are those the Dayton Planars? My bookshelves have Bohlender Graebner Neo3s in them and the highs sound very nice :). I much prefer the sound of planars over metal/soft dome tweeters and some horns i have heard in a few klipschs.

Thank you!

Bohlender Graebner Neo3s are Drool worthy according to my ole army bud. I don't think I've ever heard them myself.

Yeep, they're Dayton Planars and they should be priced about 80 to $100 each easily. They make great Dual Tweeter/Midrange for two-way systems as well. I have Rolls tastes but I'm on a Chevy budget.

So far my only worry is moving from Woofers to Sub-Woofer and the 600 to 1500Hz hole gap if I use the horn. I have a set of Pyle Midrange Cones coming today that will close this Gap.

I still got to Buff out these with some Minwax. I only wish I could aford what I wanted to build. I like the Hi-Vi Swann woofers.

[ROBSCIX]

@Miwo, I have been meaning to ask you, how does that Prelude sound with that Vintage amp you have?
Do you prefer Tube sound over solid state?? There are a few guys working together building a new DIY amplifier should have top quality sound and a great price for the parts to build it. I love DIY audio, I am also currently modding amplifier to see how much goodness I can squeeze out of it. DIY audio gets addicting.

@Donnie27, where did you get the specifications for these speakers? -Did you use software or are you just winging it?

Do you ever stop spamming? Couldn't you have just PM-ed with that OT question?

[ROBSCIX]

Actually, I didn't get to finish my post. Which I just did.
I told him about a DIY amplifier we are building. DIY is DIY, you don't get to dictate which way a threads turns.:down:

[Donnie27]

The same site I linked you and westside player too has all the DIY info you need. They do the math. All you need are the specs and size of your enclosure. I'll need to recalculate the size and length of the the port tube because the Sub Woofer is much more powerful than the lightweight twin 10's I'd planned to use.

Actually ROB it is about DIY speakers, not AMPs or Preludes.

[ROBSCIX]

NO,no I don't need the info, I have my own software for design. I was just making sure you weren't wasting your time. Your gonna make these full range?

[Donnie27]

Yes!

I'm 50 and been them building since I was 12. I have a pretty good feel for them as well. Just like you say about RightMark, sometimes you just have to experience/hear it.:)

[Donnie27]

First and formost, Madisound and Parts Express, Ebay for some parts. Their forums rock!

These guys have a good DIY section as well.

:) Nice thread, thanks! I know next to nothing about speakers, so thanks for the links.

If you don't mind could you please spell out your choices for components? You don't have to do it if its going to take too long!

[Donnie27]

I had planned on using two 10" woofers but instead I went with one 10" Sub that's wayyyyyy over-kill. I still have the option of going with the two 10" woofers later.

The cross-over are Cerwin Vega 600W 3-way

http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=17854

My stereo cuts out my sub so the two front speakers are left to perform alone. I love music in stereo. While they're great in 5.1 in blending with and covering frequency ranges not met by the rears, the don't quite cut it for stereo. The first two Polk Audio 10" woofers have this same problem and are barely better than the one 12" in my Infinity SM 120. Good for Mozart, sucks for Missy Elliot.

I love the Planar and Electrostatic Speakers but can only afford the Planars.
http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=275-085

Frequency range: 2,000-26,000 Hz is why they make great Combo Tweeter Midrange in two-way boxes. Yet, I like their highs better than its lower mids but that's not bad either, why I went with 3-way.

Midrange Horn (http://cgi.ebay.com/MIDRANGE-THREADED-HORN-DRIVER-140-WATT-118DB-NEW-C-L_W0QQitemZ280141650435QQihZ018QQcategoryZ3276QQrd Z1QQssPageNameZWD1VQQtrksidZp1638.m118.l1247QQcmdZ ViewItem)
Bi-Radial Horn Lens (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-308)

Both may end up in one of my Guitar Cabs.

What I really want to use. I get it today.
Model: PDMR5
Item Package Quantity: 1
speaker_type: Speaker driver
speakers_nominal_output_power: 100 Watts
speakers_maximum_output_power: 200 Watts
speakers_response_bandwidth: 450 - 7000 Hz
Speaker Amplification Type: Passive

I heard a set and asked what they were? I was shocked when my bud said Pyle, now that's what I get for assuming.

[Donnie27]

My goal was to keep it around $300 and built to fit a certain space in my computer room. I didn't have a lot of money to spend more on them after a few guitars, amp and cab purchases over the last 4 months. Also more RAM and a Video card in my sig. Plus as Westsideplayer pointed out the 247 5.1 Receiver ain't the best for pure applification LOL. But I'm NOT an Audiophile or have Audiophile money to blow if I were. Yet that 247 doesn't suck either.

[Miwo]

^^ Yeah I can definitely relate with the whole issue of keeping a tight budget. Pretty tough when its so tempting to just go out and buy some really nice parts. I've been busy trying to restore a pair of Infinity Monitor Jrs (3way, 12" Woofer, 2" Mid-Dome, 1" Dome Tweeter ) from the 70s, though I havn't had a whole lot of time to do so. The mids are blown on each speaker, so I have to replace them with something. I have a feeling its going to turn into an DIY abomination, considering its the first speaker I've worked on trying to restore. I've finished rebuilding the crossover with some modern / economical parts , but still need to find a replacement mid. Perhaps rip out the old tweeters, replace with Neo3, and replace the blown mid w/ a 5" woofer. That ought to be an interesting freakshow...


@Rob - I replied to your msg in PM to try not to derail this thread about Preludes and whatnot

EBay then look for my Buds.

Electro Marvin (http://stores.ebay.com/Electro-Mavin)

So until I get my Subs, I can't test them:(

Speaker is a 5" Midrange while the horn's Lens if 6 X 5.

[Donnie27]

About 9:30 last night, I tried them.

The Horn: Loud, Narrower sound stage, HOT and Brassy. Once you're in its smaller sweet spot it has nice imaging. The Midarange horn on my Optimus Mach 1 is easily better. Easily meant more a for a musical instrument. It didn't like Female voices enough. Didn't really like some synthesizers but Horns sound Live. It liked screaming guitars, will try Jimi next with it. Not Classical guitar in the lower range.

The Cone Speaker: Wider sound stage, Warm but clean, not as Brassy but loves Female voices, classical guitars and does magic with Phase Shifting Synthesizers. Very wide sweet spot and very good imaging for this cheap speaker. Sure I wanted Scan Speak, Peerless, Morel or etc.........

Horn = 93db and the Speaker = 92. The planar Tweeter = 94. I might add volume pots to balance these out

Parts of 10 songs tested on each,

"The Goose" Parlament
"I Hope You Dance" Lee Ann Womack
"Everything under stars" Fun Loving Criminals
"Tubular Bells" Mike Oldfield
"Make it with you" Bread
"Sweetheart" Mariah
"Tonite" DJ Quick
"Dust in the wind" Kansas Guitar unplugged.
A mix of Classical violin and piano
Demo made and balanced volume wise. Each song lasts from 45sec to 1:30.

Hotel California 24bit 192KHz stereo from the computer/receiver.

Ted's "Stranglehold" only tested on the Cone Midrange. Horns from Chicago and Kool & the Gang on the Horn 2nd test. Proved each devices strong point but made the choice even harder.

I'll do all the tests over again when I get the Woofers tomorrow. I need to know how well they'll blend with that woofer! I used a DVC Cerwin Vega and JVC receiver most tests. Bed time caught up with me last night.

They also have an excellent info page for explainning what all of the terms like Q whatever is.

http://www.mhsoft.nl/TSP_ex.html

What are Thiele-Small-Parameters?

A sample!

Fb - The enclosure resonance (bass reflex).

Fc -The enclosure resonance (sealed enclosure systems).

Fp -Is the free-air resonant (Fs) frequency of a passive radiator.

Q - The relative damping or system losses of a loudspeaker in an enclosure. The ratio of stored to dissipated energy

Qms - Is the measurement of control from the mechanical suspension system at resonance (Fs) which include the spider and the surround. They allow and control the movement of the speaker cone.

Qes - Is the measurement of control from the electrical suspension system at resonance (Fs) which include the voice coil and the magnet; the "engine" of the speaker.

Qts - The opposing forces from the mechanical and electrical suspensions acting against each other is the total Q of a speaker in free air at resonance (Fs).

Qmc - The Q of a speaker in a sealed box considering only the mechanical resistance.

Qec - The Q of a speaker in a sealed box considering only electrical resistance.

[Donnie27]

OK, I did another dry run with a better Sub and Larger receiver. Then there's good news and bad. The Good news is everything sounded better. The bad news is the choice is made even more difficult! Now I wish I could install both and use a toggle switch. The horn kills the speaker on most have hard stuff. Speaker kills the horn with sweetness on the soft stuff, plus it doesn't over power the Planar tweer during loud passages.

Soon, Old trusty will be boxed up and sold if I don't get a Plate Amp that supports either 2ohm or 8ohm. I don't want to only use one of the 4ohm coils. Each is a real 125 watts RMS. Woofer was built in 1996 as stamped on the basket frame.

Looking good Donnie!

[Donnie27]

Looking good Donnie!

Thanks Raptor22 now if I can choose between the loud and sassy or soft and sweet, I might sleep Tonight.:confused: Why in the hell did I have to listen to Stranglehold with those horns:( I know my Harmon Kardon will sound more like the first dry run since it has less power than the JVC. Too bad the JVC is only Pro Logic, it's stereo performance is very nice through that Super A amp.

I know I should have went with the soft dome midrange oh well.

I could learn so much about this stuff from you man... I mean I know a little but you could push me into the next dimension.

I'm just in awe of this stuff as well and still learning a thing or two as well. I love to learn and discover new things in everything I do. I think anyone claiming to know everything is a Fool! I absolutely HATE know-it-alls! Just like computers and electronics in general, technology advances changes what you already learned so you start over.

Sensitivity (1 Watt @ 1 meter). The Midrange speakers says it 92db and the Planar tweeter says its 94db, the horns says its 93db and the woofer says 96db. If it's not the fault of the Cross-over, then all of their measurements are off except for the woofer that I had tested before. So the Planar tweeter seems like its only 88db, the speakers 89db and the horn about 97db. Just rough estimates. I'm allowing for the fact that the woofer was used in a free air environment. It's been tested in and out of many enclosures many times. I might have gotten gypped on the crossovers.

I might rob one of my other speakers, stealing the horn from my heavily modded Technics or the Midrange speaker from my old set used for out side parties back in the day. Those Teledyne Horns might be the answer. But I don't want to mess that set up!

I suggest if your interested in learning more about speakers and DIY audio in general visit the forums that deal with these subjects only. This is the best place to learn and extend your understanding of the subjects at hand. Don't limit your study to one source/person/book/forum ever...read and ask as many questions from as many different experts as you can. Good luck on your quest.

Good advice Rob and that's why I gave just a few links to some of the very forums you suggested. I'd NEVER pretend to be a Know-it-all:D

Anyway, I checked on those Cross-overs (http://cgi.ebay.com/ws/eBayISAPI.dll?MfcISAPICommand=ViewItem&item=130192733530) and they're from these (http://www.savinglots.com/lotprod.asp?item=V12F). Crossover points Woofer--->600Hz Midrange--->6000Hz.

One of my imaginary friends as you called him on the other forum is coming over to lend his ears and opinion on the Horn vs. Cone debate. Right now the cone is winning. The horn lens is wrong, its NOT meant for Midrange Horns, only for tweeter horns, oh well! I should have gotten this one. (http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=270-095&DID=7)

Oh and I get my Subs today finally.

[Donnie27]

I gave up on the Horn vs. the Speakers and looked at some my other speakers. I got two Midrange Speakers from my old Pioneer SX-922's. The beauty of it is that it is much louder but just as sweet & smooth as the Pyle. Even cleaner and a seemingly wider sound stage. Almost as loud as the horn but not as harsh:) Plays a little nicer with the Planar tweeter as well. SO I'm going with them, it is a no brainier.

The horn are not in those heavily modded Technics that are nothing anymore but Technics Cross-over and enclosure.

Hadn't dusted the speakers after trying them out in the enclosures, fit only, no hookup. Now just a matter of drilling 40 holes and mounting everything. So out with the Infinity's that served me well. Then in with these by Friday I hope.

Not as efficient as the Infinity's but kills them sound wise! They desperately need something with more kick than the Harmon Kardon 247 even in the louder Stereo mode, one of the main reasons I built them. The sweet little ticks and clicks coming from the Planar tweeters are a simple Joy. Next move will more than likely be to BI-Amp them or get a bigger receiver.

[ROBSCIX]

C'mon they are not done. you know that. You are slacking, they need a nice finish added. Stain, veneer, varnish...etc. Right now they look like a kids project in wood shop and far from a finished set of DIY speakers. You couldn't wait that long to listen to them could you? LOL! You did a nice job they look great, most likely sound very good also given the specs used. Enjoy, you earned it.:)

[Donnie27]

Costs list;

Pioneer 10" Woofers DVC 4 ohm $110 shipped from OnlineCarStereo.com.
Planar Tweeters from Parts Express $87.95 shipped.
Cross-overs $31.95 shipped, EBay 101 World store.
Pioneer 5 1/2" Midrange Speakers $0
$5 for Glue and Screws
$53 total for wood and I used about $40 of it.
$8 shellac
$8 Insulation
$10.65 for Trim.
$7 Grill cloth

$308.55

I've not started on the Grill yet. I'd do a few things a little different if I built them over again, but I'd build them again in a heartbeat. The DVC 4ohm Woofer is wired to represent an 8 ohm signal to the Cross-over. The bass response is way more accurate than what I expected from any Car Sub in the price range. I got the perfect amount of Insulation according my test tracks.
Another Cross-over guy, told me the cross-over point are 600Hz and 3500Hz. Now if I could only remember where in the hell I put my test DVD:mad:

The first time I heard Halflife2 Ep2, Quake4 and the Newest FEAR i got goose bumps. Though they're not B&W's or martin Logans by a long shot, they sound wayyyyyyy better than their $300 price tag. I might move the H/K downstairs and bring the Pioneer back?????? Power Shops here I come looking for a decent Integrated AMP LOL! I easily expect better bass but the Planar won me all over again and those old 25 year old Pioneer midranges are priceless:) 3D game imaging even with it wide sound stage is very nice!!!!!!! Like EA say, I was in the Game sound wise.

First, Thank you very much Rob:D

You're right on all 3 observations, still working on the finish, I couldn't wait to hear them and yes I know I'm not finished. I'm too busy with my Birthday, selling a couple of computers and getting a Center Channel speaker built as well. Then a Superbowl Party on Sunday. Not slacking but much too busy to get finished.

Still planned;
Soft sand the finish that's already there to smooth it out.
They're not waxed and Buffed yet.
No stain but a little tint to take out the Glue (Light) spots.
Make the Grills. I already have the Grill Guides and Cloth will make the frame next week.
I also Don't like the Aluminum trim on the midrange, will paint it flat black or the same Pewter as the Sub's Gasket or dark grey to match the Tweeter.

I'm also going to leave it natural at the request of my wife.

Once tinted, soft sanded and waxed/buffed they'll look better. The Grill will be the most obvious thing seen. I didn't want industrial looks and went more with sound than looks, though looks are important as well.

Next project is already underway, replace the anemic Sony Center channel. Oh, it will match these speakers. Then soon as I build this budget back up, I might stick a Prelude or XMeridian in Computer #2 for Music Playback.

Edit: Nevermind, I looked it up, there is a lot of information here: http://www.wendycarlos.com/surround/

There's a catch though. All surround systems are not Created equal. They don't even operate the same. Example;


Digression I -- Classic Blunders to Avoid--The Worst Surround Setup -- 5 Channels

They couldn't be any more wrong than they are here. For old technology they're right, but for modern system those rules are obsolete. Sound can be sent from any direction and moving the speakers behind means the DSP has less work to do.

http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/learningcenter/home/speaker_placement.html

The ALL Creative Labs DSP's demands that "Worst Surround Setup" as they called it.

http://forum.ecoustics.com/bbs/messages/34579/129023.html

Creative's default setup for 5.1 looks more like 7.1 than traditional 5.1 placement to the sides like DDL, DTS and Quadraphonic. That's in the corners and then they (Creative) work their magic from there.:up:

[ROBSCIX]

Setup guides for speakers are just that, general guides. You should always try out different positions to get the best sound for your room, ears and speakers.
There are really no hard and fast rules just starting points I would say.

The set up for X-Fi is not just a Guide. Creative's is very specific about Speakers placement and so was Areal and Sensura. The problem is folks are confusing two similar but very different standards. Computer based 3Dsound and AVS/HTS are very different. If the Surround speakers are placed to the sides, it screws up Creative's 3D sound positioning=P The THX console also calibrates the Rear, not Side position, speakers. This is why connectiing Receivers and sound cards can be confusing, I see it tons of times.

The simple way is to Read the Manual. Creative says rear in the corners. If you're using only the Receivers AMP and the Sound Cards DSP, you use the Sound Card's Preferred speaker placement. If you using the Receiver's DSP, the side surround is preferred or no further back the 110 degrees. Creative (plus all of the tech they bought up), places the speakers to the rear. Speaker placement is -30-->30-->120--->-120. Then the 20K interpolates positions in between these.

[Donnie27]

Oh, since I added the cost of the wood to the first set of Seakers, the Center Channel cost me $32. Thanks Mavin!:up:

[Miwo]

Hey, where are the planars on the center channel? :D
You don't timbre match your setup?

While its true that center channel stuff is mostly stuff in the vocal range, I'd still match it with the same tweeter as my mains. To me surrounds are fine to get away with though.... just my preference

[Donnie27]

Upfront, I'll say approval of these speakers means little in most case for me. But I got a thumbs from someone I respect very much. I figured they sounded good but when they put a smile my Audiophile bud's face I have to admit I was pleased.

Yesterday, some more folks and I spent Halftime of the Superbowl jamming with these bad boys. Another bud even said they looked better in person than on the Pics. I'm still waiting for the guy with the test equipment to come by and test them. Honestly, I don't CARE if he comes or not, I'm very very happy with them. Can't wait to get the Grills done.

[Donnie27]

Never mind the tests, the sucker wanted to charge me to do the tests LOL!

[RAW-Raptor22]

But what should I do with my 4 allegros? Those are old and the Quad Matrix makes it wierd...

[Donnie27]

But what should I do with my 4 allegros? Those are old and the Quad Matrix makes it wierd...

Not at all. Find one of those Boston Center Ch kits that's known to blend with these very well and run 5.1 with them. Too keep everything in proportion add a simple cheap 100 Watt sub like the Dayton 10 for around $100 US. One other guy who has these Allegros is using 4 channel front and back, but all four speakers are placed in front near is rig. They sound very good this way as well. It's amazing these were seen as Budget speakers back in the day.

After hearing all 3 of my speakers playing together, my biggest critic said "You're lucky they came out that well (his way of saying he liked them), you couldn't have planned this." I asked him to come here and read about the on-the-fly changes I made to get more out of them. Thanks to two other bud's in-put as well. Help with the Cross-over info was a great.

After spending some make up time with the wife and daughter, I'll get back to work and finish the grills.:up:

[Donnie27]

After Burn in these speakers are filling a perfect VOID. Anyone who's heard them have liked them. Even a couple of folks who came to point out short comings and I knew were easily impressed. Two out of 12 said they'd went with Sealed enclosures so they'd need not be so big.

Another Adjustment to my Harmon Kardon. I had been using only Discrete LFE ch and lost bass on most none encoded material. I changed the settings to Digital 96KHz and Stereo out from my computer. This time I change the speaker setting to Sub L&R + LFE and what a difference, WOW! Now get better Idea of why so many doubted the Infinity's. They don't come close to these bad boys.

Guys the X-Fi doing digital out for music ain't that bad! Small amounts of the effects are very nice. The speaker is big and fast, sort of like a young Ali:D I do mean the Boxer.

[Donnie27]

http://img2.putfile.com/thumb/2/4016520884.jpg (http://www.putfile.com/pic.php?img=7651858)

Started roughing out the grills, still not totally set on how I'll do them.

[dirtwarrior]

Looks good. Are you going to do computer speakers?

[Donnie27]

They're used for Computer speakers first, other things afterwards. EBay and Pawn Shops are your friends. The sky is the limit.

Also look at Vintage stuff, some of it is very hard to beat. Most think powering Headphone is powerful LOL!

[Donnie27]

I also Added 12ga Speaker Wire. I was looking for 14ga but one place had 12ga cheaper, hehehe! In all honesty, I hear zero difference. The speaker wire's length is about 22ft both wires cut equal lengths. Good 16ga would have done.

You wont hear a difference, the only thing that would change would be the maximum volume you can output from the speakers. :up:

Raptor22;2764866']You wont hear a difference, the only thing that would change would be the maximum volume you can output from the speakers. :up:

They don't seem much louder either though. But I think I can attribute that to the Harmon Kardon's limited power out put.

Did you read about the the tornadoes that went through Arkansas last week? While we were out, I'm thinking lighting might killed power a few times and damaged my Sound Card a little. Yes, I have a nice Belkin Surge protector. Just so happens that I didn't have my UPS connected. Oh well, save up some money for Prelude or etc...... Had I been at home I would have unplugged everything. Nothing else in the house was damaged.

OfT
That was one the biggest, about 30 smaller ones touched down as well. That Monster twister was very deadly, it was tracked (stayed on the Ground) for 123 miles. The few states it hit caused 59 deaths and tons of Pain both physically and emotionally, keeps things in prospective.

BOnT
I'm shocked at how well these things sound with the other speakers. I'm set up for 7.1 and the last side surround is mono and tied to the left with not tests sound on the right side surround. Back and Sides can be changed independently. I loose either a Side Surround or a Back Surround from the 4 pin 1/8'' connector. These speakers love to work with the Advents better than the old BOSE. Doesn't mean those old BOSE sound bad, they don't.

I don't gamble, maybe I should. A bud, his wife, my wife and others swore then bet me I had the center channel on when I didn't. The imaging and sound stage is excellent. This was so pronounced, when I did switch to 5.1 one guy muttered without thinking, WTF!? The Phantom Center that sucks for games, sounds great for Music. I must admit though, Techno like Kraftwerk and Enigma sounds sweet in 5.1. The Monk Chants make your flesh crawl from them sounding like they're Live and at spots near you in the room LOL!

Really nice. :)

I really need to invest in a good receiver. The only real one I have is an old late 60s JCPenny model with 2x2 stereo sound... pre-quadraphonic, that and my standard Allegro G695W Quad Matrix turntable/eight-track deal. Would Dolby DTS help my quad setup sound better? I also have some old 6in bookshelf speakers in the closet, 6 channel maybe?

[ROBSCIX]

Onkyo is selling a entire HTIB with receveir for $199 refurbed. Not a bad deal.

If what I'm thinking is right, NO DTS will not perform right with Quad or with any old system. A 100&#37; Quadraphonic rig don't have In-Puts for the Center and Sub. Any time you'd get a Discrete signal you'd loose that sound or sounds.

I've had guys try to buy my old HK 730 to use just for it's Headphone support. I really wished some one on this forum had access to one:( Its very awesome power seems foreign to 99% of the folks here.

Oh, I didn't forget your love Vintage stuff and once many young folks hear this stuff it is easy to understand why. I love 2Ch Stereo in 2Ch Stereo and that was one of the Main reason for my DIY speakers. I didn't want 6 or 4 matching Dinky Satellites as one of the Playas here suggested.

[dirtwarrior]

Off topic from the thread. I am wondering why my sansui 8080 with 85 wats per chanel will outplay my sony with 120 wats per chanel.

Then let's start a new thread? Sansui's measurements are closer to the truth is the short answer.

[Donnie27]

So I got my side speakers roughed out last night. I got a lot of sanding to do. They're a little larger than I wanted but wanted hey! Got to do some Computer work tonight, Fix the Reel to Reel tomorrow. Then I can get back to the speakers later.

Again, thank you Electro Mavin on EBay for some great service and prices. I ordered some more Cerwin Vega Cross-Overs for these and will use the Bose 8" woofers and 4" tweeter/Midrange. This is Cross-Over at 3500Hz 12db steps. Again, this is for the side. I wanted Real 7.1, EAX 5 Game support, recording from my Reel To Reel and Cassette so I went a Prelude. I can't believe how much is missing in its software.

Now I have to build 5 Grills.

Oh, I got the Prelude Monday. Sold an HP Athlon 1.7GHz with WinXP (OEM from HP for $16.95 LOL). Got the Card and still had $27 left. X-Fi will be moved Computer #2 Sorry, Auzen Guy, Prelude is better but doesn't Crush the X-Fi. It's a good my Receiver had Calibration built in.

[tbone8ty]

can i use my old car speakers on my home reciever?

or do i have to like ad a resistor or something?

[Donnie27]

can i use my old car speakers on my home reciever?

No, because most Car Speakers are 4 ohm and most receivers like nothing lower than 6 ohm with the most common being 8 ohm. Besides that, most mainstream Car speakers don't have a wide enough range to hang with an average Receiver.

[Donnie27]

http://img2.putfile.com/thumb/2/5401281526.jpg (http://www.putfile.com/pic/7729257)

So I got ready for some 7.1 Action and low and behold, one of the old BOSE woofer dies. I tell ya what though, the tweeter and the one working woofer sounded great! I already ordered two more woofers from one of my EBay Buds.

Thats awesome... haven't ever been a real big fan of bose though. I have a set of 141s as my LR and RR channel hooked up to my 2x2 stereo receiver to my pc. They sound dull and incompetent but they are a rear channel none the less... or am I doing something wrong?

I'm absolutely not a Bose fan at all. Those old ones weren't bad and always, they were wayyyyy over priced for what you got. Doesn't matter, both woofers will be replaced.

The high point of these speakers are their tweeters and the are nice and bright! The blend with the Planars pretty well.

Oh yes I have too. It is a matter of how you wire them. If they are RAW speakers yes, look at those subs in my Speakers? Each consists of a Pioneer DVC 4 ohm 10" Sub:D Sure it is not a Velodyne or etc but it doesn't have to be. These are meant for Cars.

http://img2.putfile.com/thumb/1/3023343872.jpg (http://www.putfile.com/pic/7591463)

It's wired in Parallel to Equal 2ohm. If this were a single 4ohm speaker, it becomes useless. I first planned two 10" woofers, both would need to be either 2 ohm (Parallel) or 8 ohm (Series). Using a single 4 ohm speaker *could damage the Speaker or the Amp-Source, unless rated for it.

Oh, I pulled all of the insulation out and did a Playa Gansta Ghetto Bass demo for some buds, it was funny as hell as it knocked the clock off the wall LOL! I couldn't wait to re-stuff them and qucikly did.

[STEvil]

Thats your setup though. Many receivers do work at 4 ohms perfectly fine.

Also the tweeter in those, is it wired in parallel or series to the woofers? ;)

[Donnie27]

Sure, that's why I said *could and didn't come close to saying only. There are amps that can use 2 ohm speakers:D

The tweeter and mid-range speakers in my Towers are wired as singles to the crossovers. I have 3-way crossovers. Side speakers have two-way crossovers and are wired as singles was well. I've never used speaker without some type of crossover/s. At least at a minimum, I used an Inductor for the woofer and Capacitor for the tweeter. I even made a few crossovers but figured it wasn't worth the trouble.

I was a Radio Shack Kid in the 60's. We (friends and I) built crossovers, short-range radios and motorized models. Radio Shack gave the lists of parts and without knowing Jack-$#it about electronics we built them. Similar to what folks are doing with Headphone amps today.

[Donnie27]

OK, I must put off some other things so I can finish the grill dammit!

I finished replacing the Bose woofers in those rear speakers and they out performed my Advent Prodigy 1008 easily and the Advents aren't bad. The bad news is that I'm now have problems with my Center, didn't have time to troubleshoot it. Total costs of the rear speaker are $43.65:) Though they don't look as cute as the Woodys at Parts Express, I'd bet they'd kill them sound wise.

More Pictures later.

Today I got my Plate AMP from Parts Express.

Dayton SA240-B 240W Subwoofer Amplifier w/Boost (http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=300-805)

I already tried one of my refurb 16" (15.25" with a wide lip) Pioneer Woofers with only a 100W mono amp. Too big and loud for my computer room, it's for the den downstairs.:D This bad boy is very efficient. The Woofer has been tested and even impressed a not so easily impressed Bass Head. In fact, he tried to buy one. I have one in cab with my Bass Guitar and it handles everything I throw at it. Came out of a set of Pioneer CS-922A's 99db 1 watt at one meter, full cabinet was rated at 270 watts RMS. Man I loved them.,

http://www.audiokarma.org/forums/showthread.php?t=125871

The CS-922A's did have almost 1" thick High Density MDF. This is the stiff hard kind, not the soft Home Depot special. The cabinet was dead and didn't have much echo at all LOL! It did have enough that we, G.I.'s, Stuffed them anyway, 3 quarters full. Recognize the Mid Range Speakers? These were really 4 way speaker with Mid-Range spilt between the horn and M-Speakers.

I'm pulling it before I go to bed and if I get time, I'll take picts. This gets painted black, something I'd done a lot of.

The Dayton AMP has a lot of Hum and when it is not humming, it sounds OK. Man, almost a whole set and this the first set back.
Maybe it's a Ground Loop problem. I'll try it in different locations and with different speakers. The Hum doesn't kick in until I plug in the Receiver or the Computer.

[Donnie27]

Man I need something to deal with the Humming:mad:

[STEvil]

Try a different RCA, might have a broken wire inside the one you are using.

otherwise its pretty much an issue inside the amp somewhere.

See my reply in the "Show Us Your Sub" thread. I tried about 4 cables.

[dirtwarrior]

I read somewhere but its not in this thread about some older inexpensive speakers. The cabinets were crap but insides were very good componants.
All was needed was to rebuild cabinet.
Does anyone know what they are?
I think they are thrusters but not sure.

[Donnie27]

Try a different RCA, might have a broken wire inside the one you are using.

Groud Loop Isolator solved the problem. If I still have Hum, I can't hear it. Problem, the JBL still sounds better. Oh well, so much for the complete Custom set:( All of the other custom speakers sound better than the speakers they replaced except the Sub.

[Donnie27]

Wait a minute, I made some adjustments and this thing improved a lot. I still had everything set up for the JBL.

[Donnie27]

Update. I could use something better than old trusty but that Sub is rocking.

Still trying to come up some Grills but no luck in the strong but light line. Next I might try wire mess and cloth plus Dow Rods.

The Dayton really is that strong and I've already gotten it to shut down. Note is was Ear splitting loud Hip Hop Bass test. It fills the room nicely but I'd need a bigger Amp for my Den.

Looks awesome man. I would love to build a custom setup with atleast 1 massive sub, but I wouldn't even know where to start. I've never seen a custom setup like this before, how is everything wired?

I used to have 2 Memphis 12's and their Comp. 1kW amp in my car, but that was ages ago.

Awesome work man!

Thanks!

All the speakers have crossovers and are wired to them except the Sub. The 240 Watt Dayton Plate amp is barely enough though. Would love the 500Watt version. The 1000W model would be wayyyyyy over kill. In fact a clean 350W version would be perfect.

I wish I had room for the old-school Pioneer 15" and 500W Dayton Plate Amp I wanted to build.

I'm still screwing up the Grills:rolleyes:

So does your sound card plug directly into the amp? I've done some google searches and can't really find any good tutorials w/ pics, do you know of any? I'm really just interested in the sub part of things, my satellite speakers are decent.

Yes, I also have this (http://us.creative.com/products/product.asp?category=1&subcategory=16&product=14309) cable. It's connected to the analog 8 Channel direct (7 inputs + Sub) . I use a COAX for digital.

Thanks for those links, it's all starting to make more sense now. Do you know of a way to power a car amp with AC? I was just wondering because there seems to be a huge selection of car amps out there, but very few plate amps. I did a google search and ran across several forums like this: http://community.crutchfield.com/forums/thread/20900.aspx

All of which pretty much said the same thing: No. I was able to find a few forums, where a few members said that it was possible, but didn't go into details.

Oh BTW, did you ever get rid of the humming that the Dayton amp was causing?

[STEvil]

You need a large +12v DC supply to run a car amp (actually anything from 12v to 16v is ok as long as it is DC).

Can either build one yourself out of transformers and other parts or run a couple computer PSU's in parallel.

Go to Radio Shack and ask them? They should have a couple.

Old thread so bare with me. I've over bassed my system so I need something with less low-end bass and higher Mid-Bass. I'm getting wonderful top end and thunderous lows, great mids but there seems to be hole or Gap between 800 the highest the Sub-woofer can reasonably reach and lows the 3000 or so that the mid-range goes down to. Anything lower is filtered by the Crossover anyway.

So I made a trip back to my bud's on Ebay at Electro Mavin for two 10" speakers that have a 30Hz to 3500Hz range that should fill that void. But they are only 200Ws. Only if I could go back to Double woofers but the current placement might not allow that.

They're unbalanced and I can only do 6ohms. But the Sub has a higher resistance and are 93db while the woofers are 91db no tot mention;

1. I would have to Chamber the Sub separately from the rest of the Enclosure. If I didn't the Sub would make the Woofer sound like Passive Radiator or distort the woofers during heavy Bass passages.

2. I might have to amplify the Subs separately. Old JVC could do that just fine.

3. The other option is to go back and use two of the 10" in each enclosures as I had originally planned.

After burn-in, that little 240W Dayton Amp rocks. The Pioneer 12" Driver is wayyyyy under rated. My sub is not a Velodyne but give the Dayton 12" Reference Sub a run for the money. I still wish I had gotten the 500W Amp though.

[Donnie27]

I get the replacement woofers today and may get a chance to change them out this evening. I also might be close to getting my Grills sorted out. The hold is the Large main are so tall, the lenght make finding a strong material that not too heavy almost impossible. A simple I idea was suggested. Why not use multiple smaller short but stronger grills? Once the big ones are done, the small one are easy:)

[Donnie27]

Little Cheap woofer, specs already given. I once had a good Dayton Woofer (not Sub Woofer) and this one is better. LOL it just as good as my Bud's Hi-Vi. It is amazing Electro Mavin still have 6 more.

30Hz never sounded so good. That even without the Sub:up: Make no mistake here they can't touch the lows that booms from the Pioneer. The catch is that Sub can't play the Hi Bass like the woofer can just as I thought.
I was so impressed I order to more! I'm sitting here thinking now way in hell do I need two woofer in the large enclosure.

I turned down my Sub and was shocked at how smooth the Bass was.
Spam warning! Thank you Mavin guys! 4ohm woofer also make the whole speaker louder????? I think I'm going to add that other sub anyway.

This is what I'm going to do but I just needed and got matching Woofers.

Sound is improved at the expense of Loosing some deeper bass when the speakers are played without the Sub Woofer. I'm currently testing Air for four-handed Organ BWV 1068. You can hear the air coming fom the pipes LOL!, I'd first thought it just Hiss.
