This powered subwoofer features an 8" downward firing speaker driven by a 200 watt amplifier. It handles frequencies from 30Hz to 150Hz (‑10dB) and uses a variable crossover from 40‑150Hz.

The subwoofer is a 12.6" cube and weighs about 20 lbs. It features four large rubber feet, which keep the downward firing driver off the floor. It includes both line and speaker level stereo inputs, so it can be used with any amplifier. A phase control switch on the back allows you to adjust the phase of the subwoofer in relation to the rest of the system.

It has been tested by an audiophile and is in fine working order. There is cosmetic damage to the corner of the subwoofer about the size of a pinhead. Power cord is attached.

Advice from a subwoofer repairman for any subwoofer - ALWAYS turn off your subwoofer when not in use. 'Standby' is not off, it is actually on.  If you do not turn it off, standby mode keeps the circuit board hot and it will cook your subwoofer capacitors and kill it several years early.
