JL Audio Fathom F112 GLOSS BRAND NEW IN BOX

Brand new in factory packaging. Still has the shrink wrap on the outside of the shipping carton. Local pickup preferred given weight. This is a v1 model. V2 offers virtually no performance upgrade.

The JL Audio Fathom series of subwoofers are universally recognized as
among the best available. The trick, in any semi-compact sized
subwoofer, is to combine extension, power and quality. JL succeeds due
to heroic driver and cabinet design, high amplifier power, and
well-designed features. It is a sealed design with a 12" woofer and
unusually enough combines power (useful for home theater) and finesse
(as in, it sounds remarkably good for audio). A suppied microphone is
used for reduction of a single excessive frequency deviation (excess)-JL
Audio calls this "ARO", and it works quite well.
