    Reference-like Performance with Style, Beauty, and Devastating Power

    The all new S/812 powered subwoofer takes REL's medium chassis concept to reference-like levels of performance and does so with style, beauty, and devastating power. Exceling with both music and movies, it delivers incredible levels of all around performance. The S/812 provides a satisfying taste of what REL's reference model subwoofers offer, but at a fraction of the cost.

    Shattering Performance Barriers

    The S/812 is a triumphant development that exceeded every expectation of the REL design team. Every aspect of the previous generation's inner workings were examined without regard to the critical and customer-driven success of what had come before. REL's engineers turned a fresh eye to power requirements, driver improvements, and specialty filters, upgrading each to extract all the extra performance possible. Along with this came the necessary cabinet refinements necessary to take full advantage of the other technological upgrades.

    For the S/812, REL required far stronger deep bass output between 19-35 Hz, vastly improved home theater dynamics, and an even more open and spacious sound field for music and film. The design team turned to REL's NextGen5 amplifier – tuned to 800 watts, but with huge reserves of power beyond this. The team then added a light film of carbon fiber to the rear of the driver to handle the extra power, and developed two new sets of custom filters to extract the utmost in brute force and spaciousness. Finally, REL imbued the S/812 with the ability to be stacked in four-unit or six-unit line arrays, just like the company's reference models.

    Upgrades to S/812's Bass Engine

    In order for the S/812 to cope with the massive power upgrades, REL used its ContinuousCast™ Alloy Cone Driver. To permit its thin, aluminum cone to survive 800 watts and an incredibly long stroke, REL's engineers added an ultra-lightweight backing of pure carbon fiber, strategically placed over portions of the rear surface of the cone. This produces two benefits. It strengthens and stiffens the cone, and it also eliminates 'reversion;' the backwave inside the cabinet is now prevented from interfering with the main launch of bass into the room. The result is more accurate and far louder deep bass.

    There's Nothing Passive About This Passive Radiator

    The S/812's uniquely tuned passive radiator uses special suspensions, which provides an additional 30mm (1.2") of linear travel, to produce performance far beyond conventional subwoofers. This new SuperProgressive™ passive radiator produces extremely long travel allowing for very loud output, while retaining the variable stiffness of its suspension. This allows it to act like a sealed box compact 12” design at low volume and a high output 14” design at its limit.

    A Power Amplifier on Steroids – 800 Watts and Counting

    At 800 watts, the NextGen5 amplifier borrows from REL reference models and boasts huge reservoirs of power and current. This is a huge 45% increase in power compared to the 500 watts used in the previous version. (previous version was 500 watts) is needed to deliver both the The formidable power increase is a must for modern state-of-the-art home theater, as well as to produce the deepest bass in a high end two-channel hi-fi or AV system. This increase in power is necessitated by REL's development on the musical front of an all-new circuit termed PerfectFilter™ that balances both frequency extremes.

    PerfectFilter performs two seemingly disparate qualities. It extends the strong, even response of the extreme low end of bass frequencies, while simultaneously opening up air and delicacy in the middle and high frequencies of one's system. Additionally, REL applied customized PureTheatre™ filters to allow the S/812 to deliver the most awe-inspiring home theater effects ever offered in a classic REL.

    Serie S Line Array – Stacked for Ultimate Performance

    In the real world, bass possess width, depth, and height. By stacking up to three subwoofer units per side into a Line Array (stereo or home theater main L-R speakers,) the proper perspective and height of sonic events are illuminated. This elevates reproduction from conventional stereo or theater to a floor-to-ceiling panoramic, full scale perspective of each sonic event. Reviewers are lining up to marvel at the transformation of music and film into the full-scale representation that REL Line Arrays uniquely deliver.

    Zero Compression Wireless Capability

    Free yourself from the hassle and clutter of wired subwoofer connections by going wireless with your S/812. The option REL Airship system (sold separately) uses zero compression wireless technology for lightning-quick response and incredible overall performance.

    2022 Editors’ Choice Award - The Absolute Sound

    "The REL S/812 unambiguously established not only that it’s got game, but also that in extension, sheer output, and righteous slam it’s got that game down pat. However, putting these benchmarks aside for the moment, it’s the seamless system integration and nuanced transparency that distinguishes REL from many of its rivals. It became one with the character and voice of my main speakers in a way that made me feel I’d simply upgraded them to the next larger and more deeply extended model. My advice? Audition the S/812 at your peril. A single one will spoil you. But a pair of S/812s? They’ll spoil you for anything less."

    - Neil Gader, The Absolute Sound, September 24, 2020


    "Cutting-edge innovations deliver enormous power and surprising subtlety, resulting in a serious sub that sounds big and looks classy."
