Product Highlights

REL Acoustics No. 31. Specifications: 12-inch carbon fiber woofer; 900W RMS Class D amplification. This reference-grade subwoofer is engineered for those who demand flagship performance in a manageable footprint. Built with a front-firing carbon fiber cone and die-cast alloy chassis, it offers extraordinary excursion for seismic impact. The curvilinear cabinet minimizes resonance, while specialized Reference filters ensure a seamless transition with your main speakers. It includes a heavy-duty remote for precise adjustment of dual parametric filters from your listening seat. Compatible with wireless systems, this unit is also designed for vertical stacking in Line Arrays to unlock a three-dimensional soundstage that defies its physical size.

Reviews describe the No. 31 as an "iron fist in a velvet glove," lauded for its speed, nimbleness, and ability to uncover emotional nuance. Critics highlight that it transforms the entire system by opening the midrange and adding a solid foundation to the soundstage. Users appreciate the tactile remote, which makes dialing in the perfect crossover effortless. It is recognized as a rare component that makes even the finest loudspeakers sound more relaxed and authoritative. For the listener seeking to bridge the gap between high-end audio and a visceral, live concert experience, this subwoofer provides the ultimate missing link that makes every performance feel complete and truly alive.
