REL 212 Black Label Subwoofer – Reference-Grade Power and Authority Ultimate Performance for Demanding Audio Systems The REL 212 Black Label subwoofer represents the most powerful and dynamic model in the Serie S lineup. Designed for audiophiles and home theatre enthusiasts who demand uncompromising performance, it combines four 12-inch drivers with a 1,000-watt Linear Class D amplifier to deliver immense scale, speed, and authority. Engineered to energise even the largest listening spaces, the 212 Black Label excels in both reference-grade stereo systems and high-performance home theatres. Its design focuses not only on sheer output, but also on delivering musical precision, control, and seamless system integration. Key Features 1,000-Watt Linear Class D Amplifier for powerful and controlled bass performance Dual 12-inch CarbonAlloy™ active drivers paired with dual 12-inch passive radiators Massive piston area exceeding 450 square inches (1,166 cm²) for deep, room-filling bass Designed for large listening rooms and high-end home theatre systems Ideal for stereo pairs and advanced system integration Dynamic Power Meets Precision At the heart of the REL 212 Black Label are two 12-inch CarbonAlloy™ active drivers working alongside two 12-inch passive radiators. This advanced configuration provides exceptional surface area and airflow, enabling the subwoofer to produce powerful, authoritative bass while maintaining remarkable speed and clarity. With over 450 square inches of total piston area, the 212 Black Label delivers bass that is both immense and agile. It produces the explosive impact required for cinematic soundtracks while retaining the nuance, tonal richness, and precision demanded by high-resolution music systems. This balance of power, speed, and control makes it one of the most capable subwoofers in its class. Distinctive Black Label Design The 212 Black Label features one of the most comprehensive cabinet updates in the REL lineup, combining bold aesthetics with structural refinement. Key design elements include: A single vertical strake running the height of the cabinet A distinctive crown badge signalling its Black Label status A carbon fibre-framed top badge finished in deep black Warm silver bead-blasted handles with a raw titanium appearance Inside the cabinet, solid billet aluminium reinforcement secures the handles and reduces unwanted resonance, ensuring both durability and acoustic stability. An optional Premium Wood Grille further enhances the design, improving airflow while adding warmth and visual sophistication to modern interiors. 1,000-Watt Hybrid Amplifier Technology Powering the REL 212 Black Label is a newly developed 1,000-watt hybrid amplifier that combines the current delivery of high-current Class A/B monoblock amplifiers with the efficiency of Linear Class D output technology. This innovative design provides the best of both worlds: Exceptional dynamic power and control High efficiency and reduced heat output Low idle consumption of approximately 40 watts The amplifier can sustain peaks of over 1,200 watts for extended periods without strain, producing bass that is both explosive and controlled. The result is a subwoofer capable of anchoring reference-level stereo systems while delivering the scale and impact required for large-format home cinema environments. Precision Analogue Filtering REL continues to prioritise pure analogue filtering to achieve the most natural bass integration possible. All input filters in the 212 Black Label are 100% analogue, delivering extremely fast response and seamless integration with your main speakers. At the centre of the system is REL’s renowned High Level Input, which connects directly to the speaker outputs of your main amplifier. Rather than drawing power, it captures the full sonic character of the system, ensuring the subwoofer blends naturally with your speakers. For systems where High Level connections are not possible, the 212 Black Label also includes: Low-level RCA inputs Balanced XLR inputs Both utilise the same analogue filter circuit, ensuring identical speed, transparency, and integration. REL’s unique design also allows High Level and .1/LFE inputs to operate simultaneously, enabling seamless music playback while delivering full cinematic impact for movies. Airship Direct™ Wireless Connectivity In many high-end audio installations, running cables across the room is impractical or undesirable. REL solves this with Airship Direct™, an optional wireless transmission system designed specifically for high-performance audio systems. Airship Direct™ transmits wide-bandwidth compound signals, simultaneously carrying: High Level audio signals .1/LFE home theatre signals Even with the immense output of the 212 Black Label, this wireless solution maintains REL’s signature speed, transparency, and bass authority. The compact module connects discreetly to the rear panel, enabling seamless switching between music listening and cinematic playback without adjusting controls.
