Judging from everything so far if I were rating this cabinet it would be something like this...
Frequency Response 27.5-93Hz +/-3dB. -10dB at 24Hz (2m ground plane, quasi anechoic)
Frequency Response with Recommended Processing 30-128Hz +/-3dB. -10dB at 25Hz (2m ground plane, quasi anechoic)
1w/1m sensitivity (1.86v) 99dB 34-93Hz
Maximum output @1m: 142dB @ 125Hz, 139dB @ 63Hz, 134dB @ 31.5Hz, 128dB @ 25Hz
Min impedance 3.4 ohms
Recommended maximum amplifier power: 6000w program (140 to 145 volts)
Recommended Processing: 24Hz Butterworth 18dB/Octave high pass, BP EQ 107Hz Q10.0 -7.5dB, BP EQ 84Hz Q2.20 +2.5dB, BP EQ 44Hz Q2.80 -1.5dB
Weight 160 lbs
Here is what the FR looks like with 3 bands of EQ a 24Hz BW 3rd order high pass and a 4th order LR 120Hz low pass.
