These drivers are mounted in a force-cancelling arrangement for fast, powerful bass. Force-cancelling drivers avoid cabinet agitation – opposing reactive forces are nullified by rigidly mounting the low frequency drivers back-to-back. Dynamic, uncompressed and undistorted bass of heart-pounding clarity will envelop you, striking deep emotional chords. KEF promise 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 awesome power of the R400b subwoofer.
