The Fathom f112 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 f112 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 Automatic Room Optimization (A.R.O.) system. A calibrated microphone is included for the 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.
Automatic Room Optimization
Insanely powerful H.O. (High Output) systems deliver very high SPL while retaining excellent sound quality.
A wise man named Murphy long ago prescribed that a subwoofer will generally sound best in the most impractical spot in the room... a fact that home theater professionals wrestle with constantly. 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 Automatic Room Optimization (A.R.O.).
The A.R.O. system self-generates a series of calibration tones, measures the response at the listening position, analyzes the shape and magnitude of the primary response error and configures an appropriate filter to tame it. The system effectively allows for smooth, well-balanced sub-bass from a variety of locations that may have been less than ideal without A.R.O.
Dynamic Motor Analysis - DMA Optimized Motor
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
The W-Cone is a unit-body cone assembly that delivers astonishing cone stiffness with minimal mass. The shape also provides superb torsional rigidity, which is critical to maintaining voice coil alignment at the suspension limits.
Elevated Frame Cooling
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
Floating Cone Attach Method - FCAM™
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
By utilizing space wasted in conventional speakers, this ground-breaking innovation controls the W7's massive excursion without sacrificing precious cone area
Radially Cross-Drilled Pole-Piece
This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance.
Engineered Lead-Wire System
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
"The bottom line is that JL Audio’s Fathom f112 offers benchmark performance in terms of bass extension, power, transient speed, and clarity. It is beautifully made, easy to use, and gives surefire results on music and movies." - theperfectvision.com read the full review here.
