The top of the range 7.3 offers unparalled clarity combined with powerful low frequency effects thanks to a pair of whopping 8" paper/ Kevlar® bass units and a dedicated Kevlar® FSTTM midrange.Designed to slot discreetly into custom-built cabinetry, every speaker in the CT700 range can take on either front, centre or surround duties within a multi-channel theatre set-up. Each speaker used Kevlar drive units, and features B&W’s famous Nautilus tube-loaded tweeters – a pioneering technology that draws away and dampens distorting sound waves from the rear of the drive units, thereby producing a much purer sound from the front.
