JL Audio Fathom® 13.5" (345 mm) Custom Theater Subwoofer, 9" (229 mm) Deep Enclosure (CTS-113-MD900- 13TW5-SYS)

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-113-MD900-13TW5H subwoofer system is driven by a rack-mountable, purpose-tuned amplifier, capable of delivering up to 1000 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

Features

D.A.R.O. TECHNOLOGY

Exclusive D.A.R.O. technology from JL Audio uses a powerful onboard DSP to automatically optimize the subwoofer’s in-room frequency response. This leads to a superb listening experience, no matter where the subwoofer is placed.

DMA-OPTIMIZED WOOFER

Proprietary motor, suspension and cone modeling systems are used to achieve long, linear excursion capabilities with low distortion and powerful sound output.

FCAM^™ TECHNOLOGY

This “floating cone attach method” of bonding the surround/cone assembly to the voice coil former/spider structure ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

CONCENTRIC TUBE SUSPENSION^™ DESIGN

This unique design allows the motor system to be placed higher in the cone body — further compressing depth while still permitting excellent mechanical excursion.

HIGH-DAMPING FEEDBACK CIRCUITRY

This proprietary, discrete control circuit design allows our Class-D switching amplifiers to maintain excellent damping factors for improved transient behavior and fidelity.
