The combination of dual ultra-long throw W7 12-inch drivers and a very powerful switching amplifier give it jaw-dropping performance capabilities at any listening level.

Because it is built with the same driver and amplifier technology as our flagship Gotham®, the f212v2 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.

OverRoll Surround The OverRoll surround spans over the driver’s mounting flange, utilising available diameter wasted in conventional speakers. This allows the use of the wider roll necessary to control high-excursions without sacrificing precious cone area.

Plateau-Reinforced Spider Attachment A derivative of JL Audio’s VRC  technology, this bulletproof suspension attachment relieves stress from the spider material at high-excursions for enhanced reliability. Elevated Frame Cooling Technology This feature 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 minimising dynamic parameter shifts and power compression. 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 technology. Fathom® Amplifier Technologies To fully realise the benefits of  JL Audio’s long excursion driver platforms, a huge amount of controlled power is needed. These lofty power requirements create a difficult challenge when the realities of typical home electrical circuits are considered. Our electronics engineering team conducted an intense analysis of demanding program material and its dynamic characteristics in order to balance current draw and actual output power requirements relative to the subwoofer system’s impedance characteristics.

Fathom® powered subwoofers incorporate a comprehensive suite of signal processing tools. These include:

• A low-pass filter with selectable slopes (12dB/octave Butterworth or 24dB/octave Linkwitz-Riley), variable from 30 Hz to 130 Hz, fully defeatable via switch
• Fixed gain or Variable gain modes (selectable via switch), Variable gain from full mute to +15 dB over reference gain
• Input polarity reversal, via switch
• Variable phase from 0 to 280 degrees
• ELF (Extreme Low Frequency) trim cuts extreme low frequencies by as much as -12 dB or boosts them by as much as +3 dB at 25 Hz.

Controls: Front and Centre We simply couldn’t find a good reason to place user controls at the back of the product, so we put them on the front, right above the woofer. It costs more to build them this way, but some things in life are worth a few more dollars… like not having to use a mirror and a flashlight to make a level adjustment. Final Assembly Fathom® and Gotham® powered subwoofers are assembled by a highly skilled team in our Miramar, Florida factory. Each assembly technician is responsible for the entire assembly process and follows documented procedures to ensure quality and consistency. Ergonomic workstations with hydraulic lifts and multiple torque-controlled tools allow for efficient and precise assembly of every product to the exact specifications established by the Engineering Department.
