Overview — REL Acoustics 212 Black Label Subwoofer

The REL Acoustics 212 Black Label Subwoofer is built for reference-grade stereo and large-scale theater systems where speed, scale, and authority must arrive together. REL pairs a 1,000-watt (RMS) Linear Class D amplifier with a four-driver system: two front-firing 12" CarbonAlloy™ active drivers, plus one rear 12" passive and one down-firing 12" passive. The result is immense low-frequency capability with the articulation and tonal integration REL is known for, including support for running High Level and .1/LFE together for music-and-movies systems.

Designed for demanding rooms and systems, 212 Black Label is also intended to work exceptionally well as a stereo pair configuration.

Highlights & Benefits

• Effortless headroom — 1,000 watts (RMS) on tap for large rooms and high-output theaters.

• System-true blending — High Level input is designed to carry your amplifier’s sonic character for seamless integration with main speakers.
• Dual-use flexibility — run High Level and .1/LFE together so music stays natural while movies deliver full impact.
• Built for the toughest installs — the REL Acoustics 212 Black Label Subwoofer is engineered for complex systems and serious output without losing musical control.
