REL B1 active subwoofer Do one thing, do it perfectly. Confirmation of RELs motto arrives in the form of the all-new B-Series. Avoiding gratuitous embellishment, REL continue to extol their classic virtues of conservative design principles; mil-spec approaches to amplifier construction, leading edge acoustic designs, and a general build quality that reminds some of that other great British icon, Rolls Royce. With B-Series, an entirely new generation of high-end music and film sound devotees are poised to revel in the fruits of RELís labors. These newest offerings are superbly crafted to redefine sub-bass performance across both the most sophisticated music or film sound systems with equal facility. The combination of an ultra-powerful new range of bass-engines, mounted forward firing, and with a patented twin-chamber exhaust, venting out the bottom produce truly prodigious low frequency output with startling speed. Last but not least, that most British of all virtues ñ quality is present everywhere one looks. Model B1 The flagship of the new REL armada, B1, produces truly prodigious low bass at output levels ñ down to a subterranean 13Hz that will awe most listeners. An all-new ultra-long throw 12î driver designed to support several thousands of watts has been paired with an ultra high current amplifier resulting in bass that can only be described as frightening. Quality isnít everything; itís the only thing. All B-Series feature 24 crossover frequencies from 22-96Hz, using precision trimmed circuits. RELís unique design permits operation of both high-level support of main speakers and .1 channel from just one B1 sub-bass system ñ something no other manufacturer offers. Massive power supplies and outstanding build quality are the cornerstones of RELís reputation.
