KEF R400b Subwoofer
At just 31 inches square, the KEF R400b may be compact, yet it packs an
incredible punch. With a reinforced and braced sealed cabinet, the
R400b houses twin 9-inch LF drivers powered by twin 250W class-D
amplifiers. The drivers are mounted back-to-back, to create ‘force
cancelling'. This means the opposing reactive forces are nullified,
resulting in no cabinet agitation and a clean, fast, powerful bass
performance – perfect for any serious home theatre system.
