The B1 is the flagship subwoofer in Rel's B Series. Rel are one of the UK's finest subwoofer manufacturers, anyone who picks up a hi-fi magazine every once in a while will no doubt have heard of Rel and will know that they continue to produce some of the highest quality, best sounding subs around. The B1 offers more punch and grunt over any other rel sub in the B range and is ideal for large home cinema rooms. We would expect nothing less than spectacular from Rel, after all, their motto is "Do one thing, do it perfectly", the Rel B1 confirms this, pumping out an amazing 500w of power whilst remaining controlled and tight. An ultra-long throw 12" driver is combined with an ultra high current amplifier, resulting in bass that can only be described as frightening! We feel it is the floor shaking low end rumbles which really bring home the cinema experience, why not do it is style with the Rel B1 subwoofer.
