REL Acoustics Planar PL-2 Subwoofer

The REL Planar PL-2 sets a new standard for what a subwoofer can achieve in a modern living space — delivering deep, room-filling bass from an ultra-thin cabinet that occupies little-to-no usable floor space. Where traditional subwoofers demand significant floor space and architectural compromise, the PL-2 redefines the terms entirely.

Boundary Effect Coupling

The PL-2 is designed to work in close relationship with the wall behind it. REL's boundary effect coupling principle makes the wall itself part of the acoustic system, projecting bass into the room with scale, depth, and authority that feels far larger than the product itself. Whether mounted directly on-wall or placed close to the wall using the optional Planar Cart, the PL-2 integrates into modern rooms and open living spaces where traditional subwoofers struggle to find a place.

8" Flat Piston Driver

The PL-2's 8" flat piston driver was developed specifically for the Planar platform — engineered to deliver remarkable output from an ultra-thin cabinet. Producing deep, powerful bass from a driver of this depth required a fundamentally different approach to rigidity, excursion, and control. The result is fast, dynamic bass that extends to 24Hz, reaching well below the fundamental range of many acoustic instruments.

10" Boundary-Coupled Passive Radiator

Working in concert with the active driver, a 10" boundary-coupled passive radiator extends and reinforces low-frequency output, allowing the PL-2 to deliver the kind of scale and weight that the room — not the cabinet — ultimately defines.

500-Watt Pure Class D Amplification

A 500-watt Pure Class D amplifier drives the PL-2 with authority, providing the headroom required to deliver effortless, controlled bass at any listening level. Class D topology keeps the cabinet slim and running cool without sacrificing the dynamic performance REL demands of every product in its range.

VIMAR Vibration Isolation

To manage the interaction between the cabinet and the wall, the PL-2 incorporates REL's VIMAR (Vibration Isolation Material and Resonance Control) system. Integrated into the mounting brackets, VIMAR reduces the transfer of unwanted energy into the wall while preserving the speed and integrity of the bass — the result is cleaner, more controlled low-frequency performance with no compromise to the listening experience.

Built-In AirShip Direct Wireless

The PL-2 includes REL's AirShip Direct wireless system as standard, eliminating the need for long cable runs without compromising signal integrity. Installation becomes dramatically simpler, and the PL-2 can be positioned exactly where the room demands it.

Design and Finish

Available in Gloss Piano Black or Gloss White Lacquer, the PL-2's slim proportions, flowing edges, and deep lacquer finishes allow it to occupy spaces where traditional subwoofers feel intrusive. Recessed controls, concealed cable management, and optional premium wood grille upgrades ensure every detail supports a design that feels considered rather than imposed.

Technical Specifications

Who Is It For?

The PL-2 is for anyone who demands serious subwoofer performance but cannot accommodate a traditional floor-standing cabinet — whether through room design, aesthetic preference, or both. It suits high-performance stereo and home cinema systems alike, and pairs naturally with speakers that benefit from authoritative, low-distortion bass support. Those considering a stereo pair will find the PL-2 scales remarkably into larger rooms.
