REL Acoustics S/850 Subwoofer
Arriving October 2025.
An 850 W class-D amp with 12" CarbonAlloy active driver, and 12" carbon passive
The most anticipated REL release ever!
The S/850 is the foundation of Serie S, the model upon which the entire range was built. With immense reserves of power and speed, it delivers explosive attack, immense output, and the refinement to disappear seamlessly into music or film. Every design lesson proven here shaped the rest of the Serie S line.
A redesigned, wider lower cabinet enhances scale and presence, while subtle detailing ensures the S/850 looks as refined as it sounds. It comes standard with black or white cloth grilles, with the option to upgrade to premium sculpted wood for an even more luxurious finish.
As with all Serie S models, the S/850 is Airship Direct™ ready, offering wireless freedom without sacrificing speed or detail.
