Product details
The REL Reference No.31 is a sealed, front-firing subwoofer designed for high-performance music and home cinema systems. It pairs a long-throw 12-inch carbon-fibre driver with a 900-watt RMS NextGen 7 Class D amplifier in a curved, Piano Black enclosure.
Carbon-fibre drive and reference amplification
The cone and inverted centre cap use carbon-fibre construction, with a die-cast chassis supporting the driver assembly. REL’s LimitLess Limiter manages output near the amplifier’s limits, while two parametric filters provide adjustment of the deep-bass response and transition to the main loudspeakers.
Integration and expandable scale
High-level Speakon, stereo low-level RCA and dedicated RCA/XLR LFE inputs accommodate stereo amplifiers and AV systems. The Reference remote allows crossover, gain, phase and filter adjustments from the listening position. Line-array capability provides a path to multi-subwoofer installations. The cabinet receives a 12-coat high-gloss lacquer finish and retains the original Reference-series form.
