No.31

About the No.31

The REL No.31 is a pure reference-grade subwoofer engineered for audiophiles who demand the finest sound quality but lack the space for REL's flagship No.32 model. It delivers approximately 35-40% less physical volume than the No.32 while maintaining virtually identical quality and performance across all critical aspects. The No.31 features a specially developed 12-inch long-throw carbon-fiber driver with an inverted carbon-fiber center cap, powered by a NextGen 7 Class D amplifier limited to 900 watts to perfectly complement the driver's capabilities. The subwoofer extends down to 17Hz at -6dB, providing authoritative low-frequency extension suitable for large speaker systems and demanding musical content. Its sealed enclosure design with curvilinear sidewalls combines aesthetic elegance with acoustic performance. The No.31 is stackable with an optional mounting kit, allowing users to configure multiple units for enhanced bass performance. It includes dual parametric equalizers for precise room tuning, a premium reference remote control, and comprehensive connectivity options. The subwoofer is finished in piano-black lacquer with a 12-coat finish and comes with a 3-year warranty and lifetime customer support.
