ADAM Audio Sub15 15.5-inch Active Studio Subwoofer

The Sub15 is built for control rooms where the bottom octave has to be felt as well as heard: a 15.5-inch aluminium cone with 1000 W RMS behind it, flat to 20 Hz, and 120 dB SPL available at a meter.

The crossover is variable from 50 Hz to 150 Hz and everything is set from the rear panel, with XLR and RCA inputs at 10 kOhm. At 114.6 lb and 25 inches tall it is a floor-standing unit; it ships with a power cord and manual.
