REL S812 800W 12" + 12" Subwoofer

The All-New S/812 - Shattering Performance Barriers

For S/812, every aspect of the previous generation’s inner workings was examined without regard to its critical and customer-driven success. REL turned a fresh eye to power requirements, driver improvements, and specialty filters, upgrading each to extract all the extra performance possible. All this alongside the cabinet refinements necessary for those upgrades to emerge cleanly. This latest S range is a triumphant development that has exceeded every expectation of REL's design team.

REL's requirements were for far stronger deep bass output between 19-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. REL turned to their NextGen5 amplifier, tuned to 800 watts, with huge reserves of power beyond this, added a light film of carbon fibre 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 812 with the ability to be stacked in 4- or 6-unit line arrays, just like the reference models.

Key Features:
- Front-firing active woofer, down-firing passive radiator
- New PerfectFilter™ delivers increased output and deeper bass
- 12" long-throw ContinuousCast™ alloy/ carbon fibre active driver
- 12" passive radiator
- 800 watts (RMS) NextGen5 Class D amplifier
- Wireless capability with optional AirShip transmitter (sold separately)
- Stackable up to 3 units high for ultimate line array performance
- Available in High Gloss Piano Black or White

Invisible Upgrades to S/812’s Bass Engine - Pure Carbon Fibre Backing

S/812 required upgrades to its ContinuousCast™ Alloy Cone to allow it to survive the massive power upgrades. To permit its thin, aluminium cone to survive 800 watts and incredibly long-stroke, REL added an ultra-lightweight backing of pure carbon fibre, strategically placed over portions of the rear surface of the cone. This produces two benefits; it strengthens and stiffens the cone and also eliminates reversion, wherein 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 is Nothing Passive About These - Carbon Passive Radiator

REL's uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. Their 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.

Warning: Power Amplifier on Steroids - 800 Watts and Counting

At 800 watts the NextGen5 amplifier is borrowed from REL's reference models and rocks huge reservoirs of power and current. The 45% increase in power (the previous version was 500 watts) is needed to deliver both the profound output levels needed for modern theatre, as well as to produce the deepest bass in a high-end 2-channel system. This increase in power is necessitated by REL's development on the musical front of an all-new circuit termed PerfectFilter™ that balance both frequency extremes.

PerfectFilter performs two seemingly disparate qualities; extending 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 S/812 to deliver the most awe-inspiring theatre effects ever offered in a classic REL.

Serie S Line Array - Stacked for Ultimate Performance

In the real world, bass occurs with width, depth and height. By stacking up to three units per side (stereo or theatre main L-R speakers) the proper perspective and height of sonic events are illuminated. This elevates reproduction from conventional stereo or theatre 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.

Serie S - Sound & Beauty, Holistic Design & Engineering

When they began designing Serie S, REL set out, quite literally, to revolutionize subwoofers. They developed ultra-lightweight and extremely rigid Continuous Cast™ alloy cones for power and crisp clarity. They leveraged passive drivers to extend the scale beyond the cabinet size. They developed zero-compression embedded wireless for freedom of placement and a clean visual aesthetic to match its sophisticated finishes. We encourage you to experience the sound and beauty of Serie S, it will change the way you hear music and experience the
