Call for price.

Powered Subwoofer with 12-inch Subwoofer, 1800 watts


The Fathom f112v2 is a superb subwoofer solution in medium-sized rooms and is equally at home supporting a music-only system or a home theater system. The combination of an ultra-long throw W7 12-inch driver and a very powerful switching amplifier give it the kind of output normally associated with far larger subwoofer systems.

Because it is built with the same driver and amplifier technology as our flagship Gotham®, the f112v2 delivers a tremendous level of sound quality. Low distortion, excellent dynamic capabilities and shockingly deep bass extension will allow you to experience all the excitement of the most demanding cinematic material, while also being able to reproduce all the nuance and texture of your most delicate musical material.

A complete set of signal processing features is easily accessible on the front surface of every Fathom. These include a highly flexible low-pass filter, variable phase, switchable polarity, e.l.f. trim and our powerful Digital Automatic Room Optimization (D.A.R.O.) system. A calibrated microphone is included for the D.A.R.O. system. Input connections are made via unbalanced RCA connections or balanced Neutrik® combo XLR/TRS jacks. Also included is an XLR output to connect a second Fathom® as a slave unit.
