S/510 Subwoofer

Description

For S/510, every aspect of the previous generation’s inner workings were examined without regard to its critical and customer-driven success. We 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 our design team.

REL’s requirements were for far stronger deep bass output between 20-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. They turned to their NextGen3 amplifier, tuned to 500 watts with substantial reserves of power, 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, they imbued S/510 with the ability to be stacked in 4- or 6-unit line arrays, just like the reference models.

S/510 required upgrades to its ContinuousCast™ Alloy Cone to allow it to survive its massive power upgrades. To permit its thin, aluminium cone to survive 500 watts and incredibly long stroke, we 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.

REL’s uniquely tuned passive radiators use special suspensions, now with an additional 8mm of linear travel, to produce performance unlike conventional subwoofers. The 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 volumes and a high output 14” design at its limit.
