KEF R400b Active Subwoofer £999 - finished in Black
At just 14 inches cubed, 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 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.
POWER Dynamic, uncompressed and undistorted bass of heart pounding clarity envelops you, striking deep emotional chords. Your soul will awaken and the earth will move.
BASS DRIVER Massive, vented magnet assemblies and large aluminum 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.
SUBWOOFER Force cancelling drivers avoid cabinet agitation. Opposing reactive forces are nullified by rigidly mounting the low frequency drivers back-to-back.
