Deep Bass, Minimal Space

Flexible performance in an ultra-thin form.

Traditional subwoofers often demand significant floor space and careful placement to perform at their best. Planar PL-1 takes a different approach. Designed to work in close relationship with the wall behind it, Planar uses boundary effect coupling to produce deep, articulate bass from an ultra-thin form that integrates naturally into smaller and medium-sized rooms.

Whether mounted directly on-wall or placed close to the wall using the optional cart, PL-1 adapts easily to a wide range of spaces and systems. In many ways, it has become the Swiss Army Knife of REL subwoofers. Equally effective in music systems, compact theaters, unconventional placements, and even specialized applications such as center-channel bass reinforcement where traditional subwoofers often prove difficult to integrate.

Designed to Fit Naturally

PL-1 was designed for rooms where space matters as much as performance. Its ultra-thin cabinet, flowing edges, and deep lacquer finishes allow it to integrate naturally into smaller and medium-sized living spaces where traditional subwoofers can feel oversized or intrusive.

Available in black or white lacquer finishes, PL-1 transforms underused areas into opportunities for serious low-frequency performance while preserving the openness and flow of the room itself. Thoughtful details, including recessed controls, concealed cable management, and optional premium wood grille upgrades, reinforce a design philosophy where elegance and functionality exist together naturally.

To help manage the interaction between the cabinet and the wall, Planar 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.
