IN STOCK & ON DEMONSTRATION
We have been huge fans of the REL range of subwoofers since the 1990's when REL intorduced their first range of subwoofers. REL Subwoofers are unique in offering both a Line Level (RCA and XLR depending on model) and High Level inputs which can have big benefits when integrating the subwoofer with the main loudspeakers or for use with a Hi-Fi Amplifier which lacks a dedicated subwoofer output.
S/850 is engineered for listeners who want uncompromising performance with a refined, musical touch. Drawing on innovations from our Reference line, it pairs an 850-watt Linear Class D amplifier with advanced CarbonAlloy™ drivers to deliver explosive dynamics, clarity, and effortless scale. Equally at home in high-end music systems or immersive theaters, S/850 brings control and confidence to medium-to-large rooms.
