For 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 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 19-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. Turned to REL’s 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, imbued 812 with the ability to be stacked in 4- or 6-unit line arrays.
