No. 31 by REL Acoustics

Overview

The No. 31 by REL Acoustics redefines what’s possible in a compact reference subwoofer, delivering the same meticulous design ethos and sonic excellence as the flagship No. 32, but in a more space-conscious form. Powered by a 900-watt NextGen 7 Class D amplifier and featuring a newly developed 12-inch (350mm) all-carbon fiber driver, the No. 31 is engineered to deliver breathtaking low-frequency performance with precision and control. It offers a thrilling experience for both music lovers and home theater enthusiasts while maintaining a sleek, graceful design suitable for any room size.

Purpose

The No. 31 was created for those who seek uncompromised sound quality in a more compact footprint. It is perfect for spaces where the larger No. 32 may be impractical but where no compromises in performance, build quality, or features are acceptable. This subwoofer is ideal for high-end stereo systems or premium home theaters, offering exceptional bass performance and dynamic range that transform any space into a world-class listening environment.

Design

The No. 31 inherits the iconic design language of its larger sibling, the No. 32. It features elegant curvilinear sidewalls, a string grille for unrestricted airflow, and plated inset handles for effortless movement. The smaller footprint is visually striking, with a feline grace that allows it to blend seamlessly into any interior. Finished in 12-layer Piano Black Lacquer, it exudes refinement while embodying REL’s commitment to craftsmanship.
