High-Output Architectural Subwoofer System | Available at Trimira Audio
The JL Audio Fathom® CTS-113-MD900-13TW5 is a high-output architectural subwoofer system designed for dedicated home cinemas, reference media rooms, and custom installations where powerful low-frequency performance must remain concealed.
Built around JL Audio's 13TW5 13.5-inch thin-line subwoofer driver, the deeper 9-inch (229 mm) enclosure provides additional internal volume compared with ultra-shallow architectural configurations. This allows the system to target deeper low-frequency extension while maintaining a discreet in-wall installation.
At Trimira Audio, we recommend the CTS-113-MD900-13TW5 for high-performance cinema installations where substantial sub-bass output, architectural integration, and external DSP control are required.
Key Features & Technological Innovations
Patented 13TW5 13.5-Inch Thin-Line Driver
The system uses JL Audio's 13TW5 13.5-inch driver, featuring a shallow motor architecture designed to provide substantial excursion capability within an architectural enclosure.
Its large effective radiating area provides the foundation for high-output, low-frequency reproduction.
9-Inch Deep Architectural Enclosure
At 229 mm deep, the enclosure provides greater internal volume than shallower in-wall configurations.
The additional cabinet volume is designed to support extended low-frequency performance, with the supplied specifications indicating 25 Hz at -3 dB.
Rigid CNC-Machined MDF Construction
The cabinet is manufactured from high-grade MDF with reinforced mounting areas and substantial internal matrix bracing.
This rigid construction is designed to reduce enclosure flex and unwanted cabinet resonance when the driver is operating at high output levels.
Dedicated External DSP Amplification
The system is designed around a dedicated 1000 W RMS rack-mount amplifier with D.A.R.O. (Digital Automatic Room Optimization).
The external DSP platform provides the ability to integrate the subwoofer into a carefully calibrated cinema system, accounting for room boundaries and low-frequency response.
Stealth Architectural Integration
The CTS-113-MD900-13TW5 is intended to disappear behind the room architecture.
It can be incorporated into:
- Acoustically transparent cinema screens
- False stud walls
- Custom joinery
- Stretch-fabric walls
- Dedicated cinema baffle structures
The black steel mesh grille and textured black finish are designed for concealed installations.

Architectural Installation
The deeper 229 mm enclosure makes the CTS-113-MD900-13TW5 particularly suited to dedicated cinema construction where sufficient wall depth or a custom false-wall/baffle structure can be provided.
Installation planning should account for:
- Enclosure dimensions
- Structural support
- Driver orientation
- Cable routing
- Grille or fabric clearance
- Amplifier location
- DSP and room-calibration requirements
For behind-screen installations, positioning the subwoofer as part of the overall front-wall acoustic design can help create a cohesive cinema bass system.
