This is a large, single-18" driver powered by a built in 500w amplifier. In excellent shape. It comes with the original user manual, and an original glossy brochure for the entire subwoofer line. A very nice sub which has no problems hitting the lows. New this sub was $1600 - I'm asking $750+shipping, but willing to negotiate.
