Overview

The S/812 by REL Acoustics is a masterpiece of design and engineering that elevates REL’s medium chassis subwoofer concept to reference-level performance. Combining stunning aesthetics with unparalleled power and precision, the S/812 delivers breathtaking bass for both music and home theater systems.

Performance

The S/812 has been completely reimagined, with meticulous upgrades to its power delivery, driver design, and filters. At its core is the NextGen 5 Class D amplifier, which produces 800 watts RMS—a 45% increase over its predecessor. This power allows for deeper, cleaner bass that excels in both high-end 2-channel audio setups and modern home theaters.

To complement the amplifier’s immense power, the S/812 features a 12-inch ContinuousCast™ Alloy Cone, reinforced with carbon fiber backing for enhanced stiffness and durability. This innovative design minimizes distortion and eliminates internal reverberation, ensuring precise and impactful bass reproduction.

Key Features

• ContinuousCast™ Alloy Cone with Carbon Fiber Backing: The ultra-lightweight aluminum cone is strengthened with strategically placed carbon fiber for superior rigidity and accuracy, delivering deeper and louder bass with minimal distortion.
• NextGen 5 Amplifier: Borrowed from REL’s reference series, this 800-watt powerhouse provides the current reserves needed for demanding dynamic peaks and extended bass response.
• PerfectFilter™ Technology: Newly developed circuitry enhances both ends of the frequency spectrum, providing smoother highs and profound lows for a balanced and immersive soundstage.
• Advanced Passive Radiator: The 12-inch Carbon/Carbon flat cone passive radiator enhances low-frequency extension while maintaining clarity and impact.
• Dual Duty Design: Equally adept at delivering breathtaking realism in both music and film soundtracks, the S/812 is a true hybrid subwoofer.
