The C200SW
The KEF C200SW is a passive stereo subwoofer system designed specifically to operated with KEF's compact "C" Series models C15 and C25 loudspeakers. Two matched enclosures derive their power from the existing amplifier. No additional amplification is required.
Compact speaker systems are not, as a rule, very efficient, or - if they are efficient - they do not have much bass extension. Their maximum output and power handling capability is also restricted. However, they are easy to position and can deliver excellent stereo imaging and detail, with low levels of coloration.
The KEF C200SW allows the owner of the C15 or C25 to retain these virtues but with substantially increased power handling, output capability and bass extension. Each of the subwoofer enclosures contains a separate dividing network providing optimum filtering for C15 and C25, and a 200mm (8") bass unit mounted in single coupled-cavity configuration.
