S/850

The REL S/850 Subwoofer. At 850 watts, the linear Class D amplifier is borrowed from our reference models and rocks huge reservoirs of power and current. The 45% increase in power (previous version was 500 watts) is needed to deliver both the profound output levels needed for modern theatre, as well as to produce the deepest bass in a high end 2-channel system. This increase in power is necessitated by our development on the musical front of an all-new circuit termed PerfectFilter that balances both frequency extremes.

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. They turned to our NextGen5 amplifier, tuned to 850 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, we imbued 850 with the ability to be stacked in 4 or 6-unit line arrays, just like our reference models.

S/850 is built for uncompromising performance, blending power with refinement. Featuring an 850-watt Linear Class D amplifier, advanced CarbonAlloy™ drivers, and innovations from our Reference line, it delivers explosive dynamics, nuance, and effortless scale.
