Manufactures of the KEF blade technology pride themselves in calling their new concept design radical and evolutionary. They might have achieved what they set out for with the KEF blade speakers. The base drivers are placed in a side firing position and are symmetrical pairs so as to generate an individual sound field. Force cancelling technology is used to produce an undistorted sound even when the speakers are blasted at full volume. KEF speakers are so exclusive that they are not available for sale.
