REL Acoustics

British Sub-Bass Subwoofers — Reference, Serie S, Serie T/x & Serie HT

REL Acoustics is Britain’s most acclaimed subwoofer manufacturer, with a philosophy entirely distinct from the rest of the industry. REL subwoofers are not conventional low-frequency-effects (LFE) boxes — they are designed to integrate seamlessly with main speakers as a true extension of the full-range system, adding speed, weight, and harmonic richness to music while simultaneously delivering cinematic impact for film. Their patented High Level input, taken directly from the speaker terminals of the power amplifier, ensures the subwoofer inherits the exact character of the amplifier driving the main speakers — a sonic integration that no other brand achieves. Audio Dynamics supplies and professionally installs the full REL range in Bangalore, covering the Reference, Serie S, Serie T/x, and Serie HT families.

Reference Series

The Pinnacle of Sub-Bass Engineering

REL’s Reference Series represents the absolute apex of what is possible in subwoofer design — instruments that do not merely reproduce bass but reconstitute the entire harmonic and spatial fabric of a recording. Finished in 12-coat piano black lacquer requiring weeks of hand-finishing, each Reference model is stackable in Line Array configuration for truly unlimited scale.

No.32 — The flagship. A 15" pure carbon fibre driver powered by a 1,000-watt NextGen7 Class D amplifier, extending to 15Hz at -6dB. Dual parametric EQ filters, REL Reference Remote, and simultaneous High Level and LFE inputs make the No.32 the definitive tool for the most ambitious dedicated home cinema and two-channel reference rooms.

No.31 — Shares the Reference Series DNA with the same carbon fibre construction and NextGen amplification at a slightly smaller scale, delivering astonishing depth and authority for large rooms where the No.32’s sheer scale is not required.

High Performance for Music & Cinema

The Serie S is REL’s high-performance line, engineered for serious enthusiasts who demand exceptional music and cinema performance in a single elegant cabinet.

The architecture of the 212 BL drives bass in three directions simultaneously, pressurising the room for an enveloping, physical experience.

Carbon Special Black Label — REL’s most elegant Serie S model with polished stainless steel handles and carbon fibre construction, designed for rooms where aesthetics are as important as performance.

S/850 & S/550 — Available in black or white with wood or cloth grille options, these models bring Serie S performance to medium and large rooms in a more compact, versatile format.
