JL Audio Fathom f113v2 – 13.5-Inch Powered Subwoofer

Product Description

The JL Audio Fathom f113v2 combines a massive 13.5-inch W7-HT driver, 3,000 watts of short-term RMS amplifier power and advanced digital room correction in a compact, sealed subwoofer. Engineered for reference two-channel systems and demanding home theaters, it delivers deep bass extension, exceptional dynamic capability and precise low-frequency control.

Sharing key driver and amplifier technologies with JL Audio's flagship Gotham series, the f113v2 is designed for listening environments where powerful bass must be delivered without sacrificing musical accuracy. Its high-gloss black cabinet and front-accessible controls make it equally suited to dedicated private cinemas and premium living spaces.

13.5-Inch W7-HT Driver

The f113v2 features a single, ultra-long-throw 13.5-inch W7-HT driver engineered to deliver substantial low-frequency output from a sealed enclosure.

JL Audio's W-Cone construction combines lightweight cone materials with a rigid structural design to maintain control during demanding passages. OverRoll surround technology makes use of the available cone area while accommodating the driver's extended excursion.

The driver also incorporates JL Audio's Dynamic Motor Analysis technology, Elevated Frame Cooling and a radial cross-drilled pole piece. These technologies address motor linearity, thermal management and mechanical performance, helping the driver maintain consistent output during demanding movie soundtracks and dynamic music playback.

3,000-Watt Amplification

A powerful switching amplifier delivers 3,000 watts RMS of short-term power to the f113v2's 13.5-inch driver. Its design incorporates a large toroidal transformer and JL Audio's proprietary amplifier circuitry to provide the current required for high-output bass reproduction.

The combination of substantial amplifier power and a long-excursion driver allows the f113v2 to reproduce deep bass effects while maintaining control over rapid changes in musical dynamics.

With an anechoic frequency response of 20–86Hz (±1.5dB) and extension to 16Hz at −10dB, the f113v2 is engineered to reproduce the lowest frequencies encountered in music and cinematic soundtracks.

Digital Automatic Room Optimization

The f113v2 incorporates JL Audio's Digital Automatic Room Optimization (D.A.R.O.), an onboard calibration system designed to address the effects of room acoustics on subwoofer performance.

Using the included laboratory-grade calibration microphone, D.A.R.O. measures the subwoofer's response at the listening position and applies corrective equalization through an 18-band digital equalizer.

This helps reduce room-induced bass peaks and produce a more consistent low-frequency response. D.A.R.O. is particularly valuable in residential installations where the subwoofer's position may be influenced by furniture, architectural features or limited floor space.

Advanced Controls for System Integration

The f113v2 provides extensive signal-processing controls for integration with both stereo loudspeakers and multichannel home theater systems.

Its adjustable low-pass filter offers selectable 12dB- and 24dB-per-octave slopes, with crossover frequencies from 30Hz to 130Hz. Variable phase, switchable polarity and Extreme Low Frequency trim allow further adjustment to match the subwoofer to the room and main loudspeakers.

Balanced XLR and unbalanced RCA inputs accommodate a wide range of preamplifiers and surround sound processors. A balanced output supports compatible JL Audio master/slave subwoofer configurations, making it possible to expand the system with additional subwoofers.

Sealed Cabinet and High-Gloss Black Finish

The f113v2's sealed cabinet measures approximately 19.6 inches high and 16.5 inches wide, providing substantial low-frequency capability without requiring an oversized enclosure.

Its high-gloss black finish, removable fabric grille and compact footprint allow it to integrate into sophisticated listening rooms and dedicated home theaters. Front-mounted controls provide convenient access to calibration and signal-processing functions during installation.

For larger rooms or systems requiring more uniform bass coverage, multiple f113v2 subwoofers can be incorporated into a professionally designed installation.
