TDM23C and TDM23F
Hand built to Reference standards, 23F front speakers and 23C centre speakers are 3-way sealed box designs featuring KEF's legendary Ferrofluid-cooled soft dome 19mm (3/4") tweeter, two dedicated 80mm (3") midrange drivers and a pair of B169 'racetrack' bass drivers in discrete enclosures. With identical high order crossovers and drive units, the acoustic match is perfect - and with 175 Watts power handling, they deliver dramatic frontal 'slam'. Horizontal dispersion exceeds even THX ® Ultra ® standards, creating a spacious and intricately detailed 3D sound stage with startlingly real vocals; for the viewer, the sense of involvement is complete. Black Ash or White finish.
