SVS?

Good box, good sub, HORRIBLE bash amplifier.. just look at this tripe:

BASH® can produce high power levels without cost penalties typically associated with conventional amplifier designs. A linear amplifier rated at 100 Watts should be able to deliver 20 Watts continuously. If the same amplifier is to play musical transients that are 10dB louder than its rated power, the amplifier must be able to deliver 1000 watts dynamically. To deliver such dynamic power would require the internal power supply rails to be 300% higher, and the resulting power dissipated at 20 watts output to be 350% higher resulting in increases to heat sinks, power transformer, bulk capacitors, output devices and ultimately increases the cost.
You can build that SVS unit for dirt cheap.

Get a chunk of sono-tube and two MDF or plywood ends and a 4" Aero Port, sub, and amp from partsexpress.com and you're done.

Oh, here's some awesome cheap subs that will beat out the SVS unit probably: http://www.diycable.com/main/default...bd81ae111ee3ee

edit - port materials at diycable.com are dirt cheap too..
