REL S/812 12-inch Home Subwoofer

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.

Their requirements were for far stronger deep bass output between 19-35 Hz, vastly improved theater dynamics, and an even more open and spacious sound field that 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 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, they imbued 812 with the ability to be stacked in 4- or 6-unit line arrays, just like the higher-end reference models.

S/812 required upgrades to its ContinuousCast Alloy Cone to allow it to survive the massive power upgrades. To permit its thin, aluminum cone to survive 800 watts and incredibly long stroke, REL 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 also eliminates reversion, wherein the back wave 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.

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.

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 theater, 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 balances 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.
