It would be easy to look them up, but I will give a little help:
FIBERlock treated paper cone with Santoprene™ rubber surround
frequency response 26-400 Hz
power range 150-1,000 watts RMS (500 watts per coil)
peak power 2,000 watts
sensitivity 85 dB
dual voice coil design (two 2-ohm voice coils)
top mount depth 6-7/8"
sealed box volume 1.00 cubic feet
ported box volume 1.75-4.0 cubic feet
If the XXX was a 15 that would be a pretty good trade.
