                 KEF  Concord III tower floor speakers - black :
   Tower format, sealed box 2.5-way speakers featuring a quality dome tweeter

   The Celeste III and Concord III were distinctive for their industrial design, the all-round black grille cloth and matching ULS 1 and 2 single pedestal stands allowing them to stand out from the conventional square wooden boxes of the time
   Concord III was one of the first ‘two and a half way’ designs : two 8″ bass drivers being operated vertically in line at low frequencies. This arrangement improves power handling and reduces distortion at low frequencies
   The response of the lower unit is progressively reduced as the frequency rises so that only the upper unit is radiating in the crossover region. By this means it is possible to retain the advantage of twin drivers at the low end of the range without the phase interference effects usually associated with multiple drive units
   Celeste III was an 8″ two way closed box design with newly developed drivers and a sophisticated crossover network. Both models were designed for use with music centres and amplifiers with as little power as 10 watts per channel and benefited from KEF’s total design concept and digital evaluation techniques
   The B200 bass drivers for the Celeste III and Concord III featured a new three-sided chassis specifically designed to be mechanically isolated from the cabinet – the first example of driver decoupling in the KEF range
   They were also the first KEF bass drivers to use a paper diaphragm – by this time paper diaphragms were being manufactured with good consistency and the lower moving mass contributed to the high sensitivity target for these systems
