REL’s new S/850 has taken the top subwoofer gong at the Hi-Fi+ Awards 2026, and the specs make a compelling case. It’s a 12-inch driver with an 850W Class D amp, a carbon fibre-infused acoustic bass radiator, and a cabinet redesigned to go lower and hit harder than the S/812 it replaces. The clever bit is REL’s High Level input — connected directly to your amp’s speaker terminals, so the sub sees exactly the same signal as your main speakers. The result, according to Hi-Fi+’s reviewer, wasn’t just better bass. It was clearer guitars, more defined piano, better-separated vocals. A subwoofer that makes the whole system sound more musical is the only kind worth caring about.
