At just 36cm cubed, the KEF R400b may be compact, yet it packs an incredible punch. With a reinforced and braced sealed cabinet, the R400b houses twin 229mm LF drivers powered by twin 250W class-D amplifiers. The drivers are mounted back-to-back to create a ‘force cancelling’ effect. 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.
Dynamic, uncompressed and undistorted bass of heart pounding clarity envelops you, striking deep emotional chords. Your soul will awaken and the earth will move.
Massive, vented magnet assemblies and large aluminium voice coils drive the lightweight yet stiff, strong hybrid cones. Bass output is faster, cleaner and more accurate. Satin anodised elements contribute to the unit’s elegance, while the diameter of the trim ring accentuates a visual sophistication that belies the speaker’s awesome power.
Force cancelling drivers avoid cabinet agitation. Opposing reactive forces are nullified by rigidly mounting the low frequency drivers back-to-back.
