RE: Some good compilations of subwoofer measurements

0.7% THD at 20 Hz is extremely low, even at 90 dB. Almost seems too good to be true.

The big Funk Audio subs might be able to equal that. Unfortunately, the distortion measurements made on the FW18 and FW21 started at 110 dB. The FW21 stays under 1% THD through the middle and upper bass at 110 dB, and it has a relatively slow rise in distortion at lower frequencies. So it's conceivable that it could remain flat at 1% or less down to 20 Hz if tested at 90 dB. Nothing else I've seen comes close. You're doing well if your sub can stay under 2-3% THD at 90-95 dB over most of it's range above 30 Hz. And all but the biggest subs show a sharp rise in distortion below 30 Hz.
