SFC-12 Subwoofer System –In-Wall Subwoofer With Aluminium Backbox

SFC12-SYS Custom-Engineered Extruded Aluminum Backbox

Most in-wall subs rely on inconsistent cavity volume. Not this one. The extruded aluminum SFC12-SYS backbox provides a rigid, acoustically tuned enclosure that ensures performance doesn’t change with every installation. Unlike typical drywall or stud cavities that vary wildly, this custom-engineered enclosure delivers consistent bass response and precision, every time. It’s the level of control professionals need—and clients expect—for reliable, room-perfect low frequencies. No compromises, no guesswork—just tight, powerful bass that integrates seamlessly into any environment.

All SFC12-SYS installations require the dedicated backbox, which is sold and shipped separately to accommodate pre-construction timelines. This approach ensures the backbox can be installed during rough-in, with the subwoofer and amplifier added later during trim-out—aligning with standard job site workflows.

Purpose-Built for New Construction
The SFC12-SYS redefines what an in-wall subwoofer can be—engineered as a complete system with the installer in mind. With a defined enclosure volume and flexible mounting system, it removes guesswork and minimizes surprises on site. Pre-wire. Rough-in. Trim-out. It fits your workflow.

Vibration Isolation That Works
Keeps Bass In the Room— Not In the Walls
The SFC12-SYS is engineered to keep mechanical energy where it belongs—with a proprietary isolation mounting system that prevents vibrations from transferring into the structure. Combined with Paradigm’s advanced Vibration-Cancelling technology—perfected in our Signature Sub, Persona Sub, and flagship Persona 9H—it delivers deep, articulate bass without shaking walls or triggering callbacks. Big impact. Zero buzz.

Performance That Speaks for Itself
Dual Carbon-X Drivers in a Force-Cancelling Configuration
The SFC12-SYS brings serious low-frequency muscle to in-wall installations, leveraging dual 3.75" x 15.35" Carbon-X drivers with oversized super-neodymium motors and Paradigm’s patented Active Ridge Technology (ART). This combination delivers thunderous, controlled bass with vanishing distortion and zero coloration—even at reference volumes.
From cinematic explosions to orchestral crescendos, the SFC12-SYS delivers clarity, depth, and impact that defies its form factor—setting a new benchmark for in-wall bass.

Power-Matched for Maximum Output
Engineered specifically for use with Paradigm’s X-500 or SVX-1202 amplifiers to ensure optimal DSP performance, safe operation, and maximum output. Using a third-party amp? Don’t. It’s a poor match and will compromise performance.

Clean Finish. Zero Compromise.
Bezel-free Grille. Paintable Finish. Magnetic Mounting.
Once it’s in, it disappears. A bezel-free low-profile grille mounts magnetically for easy service and blends cleanly into any space. Paintable to match walls or trim for complete design flexibility.
