Description

Description

At just 14 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.

Legendary KEF R Series
Featuring many of KEF’s latest innovations in premium hi-fi and home theatre loudspeaker technology, the all-new R Series makes genuine audiophile standards of entertainment more affordable than ever before. Stunningly fluent new Uni-Q driver arrays combine with potent new bass drivers and many ingenious refinements to create a rich, spacious sound image of such accuracy that it approaches the benchmark standards of KEF’s legendary Reference Series.

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.

KEF Recertified Product

Buying a KEF open box product is a great way to get "like-new" products at a considerable savings. Every product has been thoroughly tested, cleaned and otherwise renewed to original condition. Next it’s repackaged in a new box with all original accessories included. And for your piece of mind and protection, your purchase is covered by a full 5 year parts and labor warranty (1 year on electronics) valid at any authorized KEF repair center (you can look-up locations online here or call 732-683-2356)

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked cabinets, broken grilles, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
