      Twin 9 inches driver 'force-cancelling' subwoofer

      The R400b is just 14 inches high but with twin bass drivers and 500 Watts of power, it's made for serious home theatre systems. The R400b's reinforced and braced cabinet houses twin 9 inches LF drivers powered by two 250 Watts class-D amplifiers. The drivers are mounted in a ‘force-cancelling’ arrangement for fast, powerful bass.

      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.

      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.
