I found some more info on the cab, 150 lbs with the installed 100w amp. Active cabs have come a long way in 50 years.
Some info on the woofers from my testing:
7.1 ohm dcr
Fs 27hz
Qts seems similar to the Eminence Alpha 15 (qts 1.26) based on observed cone movement, so it's good for low power open cab usage.
Efficiency seem similar to the Alpha 15 when measured at 70hz and 40hz. The Alpha 15 plays higher into the midrange though.
Power handling at 41hz low E is around 21 watts or 13 volts assuming a nominal impedance of 8 ohms in free air use with a peak to peak cone movement around 11mm. Or 15 watts or 10 volts at 31hz low B. At 16hz for organ fans it's like 7or 8 volts. After p-p cone movement increases past11mm the distortion rises the mechanical limit around 15mm p-p.
