I next ran the EK dual top (green line) to see if dual tops were inherently compromised. I compared the data also to two individual tops multiplied by two (red line):



Conclusions:
- a dual top can be as efficient as two single tops
- EK > Laing > Bitspower
- It's also worth noting the EK and BP tops were both ~2dB quieter than the Laing top when running @24V (38dBA vs 40dBA)
