Rel Acoustics 212 Black Label

Technology

Driven with Authority

Driver development lies at the core of every REL. For 212 Black Label, both active and passive elements were re-engineered to handle the massive outputs made possible by its uprated 1,000-watt amplifier. Dual 12" CarbonAlloy™ active drivers, fitted with lightweight carbon-fibre center caps, release more energy on every stroke, yielding speed and control at levels unheard of in earlier designs. To match, the dual passive radiators were redesigned with longer suspensions and greater excursion, allowing the system to traverse massive distances without strain. The result is a subwoofer that plays some 40% louder than its predecessor. For the engineers, the real triumph was refining every nuanced aspect of performance, made clear each time ultra-dynamic movie scenes or sprawling, complex pieces of music flow effortlessly without strain.

Outrageousness Amplified

Like its Carbon Special Black Label stablemate, 212 Black Label is powered by a newly developed 1,000-watt hybrid amplifier that marries the current delivery of high-current Class A/B monoblocks with the efficiency of a Linear Class D output stage. This best-of-both-worlds design delivers immense dynamic power while consuming just 40 watts at idle — no more than a handful of night lights. Peaks of over 1,200 watts can be sustained for extended periods, producing explosive authority without strain. The result is an amplifier that sounds urgent, driven, and unshakably powerful, yet refined enough to underpin reference-grade stereo systems and anchor the largest theaters with complete composure.

Analog Filtered to Perfection

All REL input filters are 100% analog — among the fastest ever offered in a subwoofer. We choose analog because it is the only way to achieve natural sound. At the center is our famous High Level Input, which connects directly to the speaker outputs of your main amplifier. This does not draw power; instead, it carries the complete sonic signature of your system, allowing REL to blend seamlessly with your speakers, a trait reviewers have celebrated for decades. And for systems where High Level isn’t possible, our low-level input employs the very same filter circuit, available via both RCA and XLR connections, delivering the speed, naturalness, and integration REL is known for. For theatre and dual-use systems, REL allows High Level and .1/LFE to be run together, so music gains natural integration, while movie soundtracks deliver the full impact intended by the mix.
