    The world's best subwoofers -



    "The JL Audio Fathom is of reference quality and a benchmark by which all other subwoofers can be judged." - Robert Harley, The Absolute Sound



    YouTube video. Combining a state-of-the-art, DMA-optimized long excursion driver with a highly efficient, proprietary switching amplifier, our E-Subs deliver a level of performance that belies their compact dimensions and cements their value.

    Check out the key technologies and components featured inside JL Audio's 12'' E-Sub E-112 powered subwoofer below.

    JL Audio E-Sub e110 10-inch (1200w) and e112 12-inch (1500w) powered subwoofers -

    Applying a series of our key technologies, E-Sub powered subwoofers deliver exceptional sound quality, power and value in a wide range of demanding applications

    E-Sub drivers employ our exclusive DMA technology to optimize the drivers' motor strength, ensuring linear behaviour over a very long excursion range. Unlike typical steady-state modelling systems, DMA takes into account the dynamic shifts created by current flow and back EMF under real power conditions, with real program material. The payoff offered by DMA optimization is a driver that faithfully tracks its input signal, at all listening levels, leading to superior bass definition and dynamics.

    The extreme mounting depth of the E-Sub driver is very deliberate. It permits wide gaps to exist between the three suspension elements (the rubber surround and the dual spiders), imparting exceptional mechanical stability over the driver's full excursion range. This further improves linearity, reduces distortion and enhances long-term reliability. In a stroke of engineering elegance, the E-Sub’s steel front mounting flange forms the entire front baffle of the finished product, while the driver’s back-plate is threaded and bolted to the rear wall of its enclosure for support.

    To power these innovative drivers, we engineered a completely new switching amplifier with a regulated, switching power supply, making its chassis more compact, lightweight and efficient, while still delivering ample, clean power to fully exercise the E-Sub driver's performance envelope.

    Conveniently controlled from the E-Sub cabinet’s top panel, the amplifier incorporates studio-grade signal processing to make adjustments a much more enjoyable experience than rear–mounted controls found on most powered subwoofers. An attractive cover hides and protects the controls during normal use.

    The feature set has been designed to allow the use of E-Subs in a wide range of applications, from full home theatre systems to dedicated two-channel music systems, to desktop audio workstations. Analogue inputs are provided for unbalanced line-level signals or speaker level signals. Dedicated line outputs are included to make a bi-amped system arrangement with no additional hardware required. Useful in combating ground-related noise problems, a rear panel switch configures the line level inputs as grounded or isolated.

    The E-Sub’s active crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass filter feeding the subwoofer's amplifier and a high-pass filtered signal exiting its line outputs. When the on-board crossover is defeated, as is typical in a home theatre installation, the line outputs deliver a pass-through, buffered signal identical to its line inputs, easily permitting multiple E-Subs to be interconnected in a ‘daisy-chain' arrangement. Switchable polarity and a fully variable phase control round out the signal processing section. All signal processing is performed in the analogue domain, ensuring very low latency in critical applications.

    Precision-built in JL Audio's U.S. factory, all E-Sub's are individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theatre system.

    JL Audio CR-1 Active Subwoofer Crossover -


    JL Audio's CR-1 Active Subwoofer Crossover is at Musicraft (Derby)

    The lucky few who have heard a well-integrated subwoofer in a great audio system know that the subwoofer's effect is profound. While everyone expects the bass extension to improve, most are shocked at the transformation that occurs in the main speakers. They simply open up, delivering improved dynamics, superior imaging and more low-level detail. Many describe it as the greatest speaker upgrade they have ever made.

    Over the years, we have calibrated many subwoofer systems in highly critical listening environments, and we have been frustrated by the limitations of active crossovers we have worked with. Tired of struggling with "blunt instruments", we felt that a higher precision tool was needed, so we decided to build it and call it "CR-1". When properly set up, CR-1 creates a listening experience in which the subwoofers and main speakers become one, delivering a cohesive and compelling sonic presentation.

    The CR-1 Active Subwoofer Crossover has been designed by audiophiles, for audiophiles. We believe it has no equal, offering a powerful combination of subwoofer/satellite tuning features, and a complete commitment to analogue signal purity.

    JL Audio's CR-1 Active Subwoofer Crossover is at Musicraft (Derby)

    CR-1 is built around two banks of precision Linkwitz-Riley low-pass and high-pass filters. Multiplying DACs with monolithic ratio matching are employed to adjust the analogue circuit's filter frequencies. This offers superior tracking behaviour and far more precise left/right channel balance, compared to conventional approaches.

    Another of CR-1's unique and powerful features is a pair of rotary controls that control the damping of each filter bank. These damping controls dramatically improve the acoustic summing through the crossover region, by compensating for each speaker system's frequency response. At the center of the front panel, a single intuitive, rotary control permits quick adjustment of the relative level between the subwoofer(s) and main speakers.

    To minimize distortion and noise, CR-1 employs top-grade component parts in its all-analogue audio circuitry: 1% precision resistors, JFET-input audio-grade op-amps, polypropylene film-and-foil capacitors and metallized-polypropylene film capacitors, to name just a few. We also build CR-1 right here in the U.S.A., to ensure top quality and dependability.

    CR-1's input-output design makes it equally adaptable to studio, mastering suite or audiophile two-channel playback environments. To accommodate dual-mode systems, we also include a bypass feature that engages a pass-through from a dedicated "Managed Bass Input" on the rear panel, to the CR-1's subwoofer outputs. This makes it convenient to switch from two-channel to multi-channel mode.

    CR-1 is the ultimate tool for subwoofer integration.

    The world's best and the Formula 1 of subwoofers -



    "The JL Audio Fathom is of reference quality and a benchmark by which all other subwoofers can be judged." - Robert Harley, The Absolute Sound

    JL Audio Fathom® v2 High Speed, Ultra High Power, Ultra High Definition powered subwoofers -

    The challenges associated with designing high-output compact subwoofer systems can be quite daunting. In most cases, designers sacrifice low-frequency extension or output capability in order to keep the design small.

    The Fathom® v2 subwoofers sacrifice nothing, thanks to the dynamic advantages of their proprietary JL Audio woofers. These exceptional drivers allow for a true subwoofer passband and very high output, while keeping distortion well below audible thresholds. To extract full benefit from the excursion envelope of its woofer, each Fathom® v2 employs an exceptionally powerful switching amplifier with a large toroidal transformer and a patented circuit designed to enhance control and fidelity. The audible benefits of these advantages are truly profound, and attested to by the most respected reviewers in the audio business.

    JL Audio Fathom® f212 v2 Dual 12-inch Subwoofer Drivers, High Speed, Ultra High Power 3600w, Ultra High Definition powered subwoofer -


    JL Audio's Fathom f212 v2 High Speed, Ultra High Power 3600w, Ultra High Definition powered subwoofer is at Musicraft (Derby). Unfathomable sub bass by JL Audio.

    The f212 v2 is the ultimate expression of the Fathom v2 formula. It is ideal for larger spaces thanks to its higher efficiency and higher power output. 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 v2, the f212 v2 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 v2. 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 v2 as a slave unit.
