No.31 REFERENCE  is nothing less than a pure reference model, sculpted from the flanks of the remarkable No.32, but using a newly developed 12″ (350mm) all carbon fiber driver. Every facet of No.31 has been comprehensively upgraded and refined from its predecessor. No.31 delivers the classic Reference filter used in No.32, the same dual parametric filters, a driver that handles three times the power to deliver a truly thrilling experience.

No.32’s NextGen 7 Class D 1,000 watt amplifier also lives inside No.31, only limited to 900 watts to ensure the perfect complement to the 12” bass engine within No.31. This allows the maximum dynamics to be delivered while ensuring a long, cheerful life for both components. Here too, the Limitless Limiter,™ which permits the amplifier to tiptoe right up to its limit without audible compression is part of the magic, conveys a rhythmically effortless quality. Also, its dual parametric filters allow precise micro-tuning; the deepest bass is slightly reinforced, while the upper ranges of bass can be gently trimmed to ensure a brilliantly rendered transition from bass to the main speaker. The electronic design of the reference range is itself artistry.

Includes a remote control.
