S/510 takes REL’s compact-medium chassis concept to reference-like levels of performance and does so with style, power and incredible speed. It delivers incredible levels of all ‘round performance. S/510 allows those with less space, or when pairing with high end speakers that are slightly less robust to have a perfect dance partner when the S/812 is simply too much of a great thing.
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.
Our 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. We turned to our 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, we imbued S/510 with the ability to be stacked in 4- or 6-unit line arrays, just like our reference models.
