JL Audio Fathom F-112 Gloss Subwoofer

Outstanding self-powered subwoofer from JL Audio with 12" driver and built-in crossover/amplifier/etc. Also utilizes an included microphone and JL Audio's "ARO" (Automatic Room Optimization) circuitry to locate and rectify the primary response error generated by the room placement/subwoofer coupling. Most importantly, the combination of a superb overbuilt driver and heavy-duty cabinet produce reference-quality bass response. This is a true audio-grade sub! Condition is excellent, with no obvious nicks/scratches/etc (any gloss finish, as this sub has, is unlikely to be microscopically perfect, but is very good indeed). It has always been used as part of a dedicated A/V system, no pets or smoking allowed. I am the original owner, and Included are the sub, original box with packing, manual and calibration mic, power cord and a packet containing non-marring gloves for handling the subwoofer as needed. I am a long-time Audiogoner going back to paper newsletter days, and a verified PayPal user. At the asking price only, I will include ground shipping to the lower 48 US States, and will cover PayPal fees.
