The Usher 1801PA subwoofer features an 18 driver size and a RMS power of 300 watts. I purchased two of these for a project, but this one was never used. I believe this model is no longer available from Usher. The specs are: Fs=32hz., Vas=11.8 cu.ft., Qms=12.5, Qes= .34, Qts=.33, Re=5.3, Xmax=.3 in., Le=.79, Sens.= 97 db 1w@1m. I would use it in a 4-6 cu. ft. ported box tuned in the mid 30s. Happy bidding!
