REL Carbon Special Black Label Subwoofer - Piano Black

Editor’s Choice 2022 – The Absolute Sound

Product of the Year 2021 – Hi-Fi+

Limited Edition Powerhouse, Built for Pure Performance

The REL Carbon Special Black Label is a reference-grade subwoofer that combines cutting-edge engineering with a sleek, limited-edition Piano Black finish. Designed for audiophiles and home theater enthusiasts who demand uncompromising performance, it delivers deep, controlled bass that transforms any system into an immersive experience.

Bass That Redefines Authority

At the heart of the Carbon Special Black Label is a 12-inch, ultra-lightweight carbon-fiber driver powered by a massive 1,000-watt NextGen5 amplifier. Supporting it are dual 12-inch carbon passive radiators, extending low frequencies with speed, weight, and musicality. The result is bass that feels physical yet refined—perfectly matched to both delicate acoustic recordings and high-impact cinema soundtracks.

What the Experts Say

“The Carbon Special Black Label delivers bass with such speed and scale that it vanishes into the system, leaving only music and emotion behind.” – The Absolute Sound, 2025

Engineering Beyond Ordinary

REL equips the Carbon Special Black Label with their ContinuousCast carbon-fiber driver cone, chosen for its ideal combination of stiffness and lightness. The dual passive radiator system expands output without adding distortion, while the Piano Black lacquer cabinet ensures beauty that lasts. Internally, REL’s NextGen5 1,000-watt Class D amplifier supplies effortless reserves of power, keeping transients tight and dynamics limitless.

Connectivity for Music and Movies

With REL’s High-Level Neutrik Speakon input, the Carbon Special Black Label integrates seamlessly into two-channel systems, locking perfectly with your amplifier’s output. A separate .1/LFE input guarantees blockbuster movie soundtracks hit with chest-thumping force. Independent inputs allow the subwoofer to optimize for music and home theater simultaneously.

Built for Big Systems and Bigger Rooms

Whether anchoring a high-end stereo system or forming the foundation of a dedicated theater, the Carbon Special Black Label excels in large spaces. Its line-array stacking capability allows multiple units to work together for even greater impact and control.

A Subwoofer That’s Both Rare and Remarkable

Finished in deep Piano Black, this limited-edition model embodies everything REL stands for—innovation, craftsmanship, and uncompromised bass.
