JL Audio Fathom f113v2 Subwoofer

The Fathom f113v2 is a heavyweight subwoofer capable of filling the most demanding rooms with powerful low-frequency output and reference-class sound quality. The combination of an ultra-long throw W7 13.5-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 f113v2 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.

Digital Automatic Room Optimization (D.A.R.O.)

Summary:
JL Audio's exclusive D.A.R.O. technology uses a powerful on-board DSP to automatically optimize the subwoofer's in-room frequency response. This leads to a superb listening experience, no matter where the subwoofer is placed.

Detailed Information:
In typical listening spaces, subwoofer and listener placement have a profound effect on the accuracy of low-frequency reproduction. While we always recommend that you place your subwoofers in good-sounding locations, we know that these often can be impractical locations. In the real world, subwoofer placement almost always involves a compromise between sonic performance, practicality and aesthetics.

To face this dilemma head on, JL Audio subwoofer systems incorporate a clever piece of technology called Digital Automatic Room Optimization (D.A.R.O.). The D.A.R.O. system self-generates a series of calibration tones, measures the frequency response at the listening position, and automatically configures an 18-band, 1/6 octave equalizer for a flat end-result. The system effectively allows for smooth, well-balanced sub-bass from a variety of locations that would have been less than ideal without D.A.R.O.
