Custom Theater Subwoofer System with Dual 13.5" (345 mm) Subwoofers, 9" (229 mm) Deep Enclosure

Born from JL Audio s revolutionary Fathom® in-wall subwoofer system, CTS subwoofers are designed to deliver uncompromising bass performance for virtually any custom integrated application.

Centered on a groundbreaking 13.5" thin-line driver, all CTS enclosures are critically constructed with extensive internal bracing aimed at improving rigidity, while keeping a low profile and minimal wall thickness. Offered in five variants, each sealed enclosure features medium-density fiberboard (MDF) construction with reinforced areas to facilitate direct-to-frame mounting.

The CTS-213-TD900-13TW5H subwoofer system is driven by a rack-mountable, purpose tuned amplifier, capable of delivering up to 2000 watts of clean power. JL Audio s powerful DSP engine is also on hand, including our exclusive Digital Automatic Room Optimization (D.A.R.O.) system to ensure a smooth response, even in challenging rooms.

Crafted for the most demanding home theater or music system applications, Fathom CTS subwoofers are engineered to deliver legendary JL Audio bass performance and fidelity.

  • Includes black steel mesh grille
  • Enclosure finish: flat black (hidden from view when installed)
  • Enclosure construction: computer numerical control-cut high-grade MDF


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.

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.

Concentric Tube Suspension

Our Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer.

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.
