REL S/812 - Flagship High-end Subwoofer Performance
The All New S/812
For the REL S/812, every aspect of the previous generation’s inner workings were examined without regard to its critical and customer-driven success. REL turned a fresh eye to power requirements, driver improvements, and speciality 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 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 S/812 with the ability to be stacked in 4- or 6-unit line arrays, just like their reference models.
Invisible Upgrades to S/812’s Bass Engine
The REL 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 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.
