Powered Subwoofer with Dual 13.5-inch Subwoofer Drivers, 3800 watts

Your first look will tell you that you are looking at something special... your first listen will confirm it beyond a shadow of a doubt.

The beauty of the Gotham® extends well beyond its exotic design and exceptional craftsmanship, aiming right at the emotional core of musical and cinematic enjoyment. This is a subwoofer system with limits that exceed the needs of the typical home theater application, delivering a weight and integrity of reproduction that can only come from a system that is always in control. Its allure lies as much in its ability to convey subtleties as in its prodigious output capabilities. It is simply devastating.

A luxurious, handcrafted gloss-black finish is complemented by machined aluminum and stainless steel accents for a look and feel that fits perfectly with the finest home furnishings. More importantly, the beautiful cabinet houses a pair of JL Audio's highest-technology subwoofer drivers. When demanded by program material, the Gotham's prodigious switching amplifier can deliver 3800 watts of RMS power, to take full advantage of the twin drivers' four inches of peak-to-peak excursion capability. This ensures that the Gotham can breeze through material that makes other subwoofers go into clipping, limiting or distress.

A very complete set of signal processing features is easily accessible on the top surface of the Gotham. 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 Gotham® as a slave unit.

Listening to a Gotham® reveals an entirely new dimension of subwoofer performance... a dimension so satisfying that listening to lesser subwoofers will forever become an act of compromise.

Finish: Gloss Black, hand-finished to the highest furniture-grade standard.

Grille finish: Black fabric (separate grilles for drivers and controls)

Enclosure Construction: Fiberglass, 2-inch (52 mm) wall thickness

Technology
Automatic Room Optimization (A.R.O)

JL Audio's exclusive A.R.O. technology is designed to easily and automatically optimize a subwoofer's in-room response. Taking just a few minutes to accomplish, this innovative feature delivers a superb low-frequency listening experience, no matter where the subwoofer is placed.

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.

W-Cone (U.S. Patent #6,496,590)

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 (U.S. Patent #6,219,431 & #6,229,902)

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™ (U.S. Patent #6,501,844)

This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

OverRoll™ Surround

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 (U.S. Patent #6,243,479)

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 (U.S. Patent #7,356,157)

Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

High-Damping Feedback Circuitry (U.S. Patent #6,441,685)

This proprietary, discrete control circuit design allows our Class D switching amplifiers to maintin an excellent damping factor for improved transient behavior and fidelity.

Built in U.S.A. with Global Components

JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
