Planar PL-1
Flexible performance in an ultra-thin form.
Traditional subwoofers demand space and careful placement to perform at their best. PLanar PL-1 takes a different approach. By working in close relationship with the wall behind it, Planar uses boundary effect coupling to project bass into the room with surprising depth, clarity, and scale.
The result is performance that feels far larger than the product itself. 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, and spaces where traditional subwoofers simply don’t work.
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 Gloss Piano Black or Gloss White Lacquer, PL-1 can either blend quietly into the room or sit within it more intentionally. Thoughtful details, including recessed controls, concealed cable management, and optional wood grille upgrades, reinforce a design philosophy where performance and presence are carefully balanced.
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.
Dual Drivers: Dynamic Performance
PL-1 uses twin long-throw 6.5″ drivers specially developed from proven REL driver platforms to deliver fast, dynamic bass from an ultra-thin cabinet.
Working together, the dual-driver configuration increases surface area and impact while preserving the speed, articulation, and control that define REL performance. The result is deep, engaging bass that brings music and theater systems to life without overwhelming smaller and medium-sized rooms.
Boundary Coupled Bass
A specially tuned 10″ long-stroke passive radiator fires toward the wall behind Planar, using boundary effect coupling to reinforce and expand low-frequency output.
With significant excursion and precise tuning, it transforms the wall into part of the acoustic system producing surprising depth and scale from a cabinet only inches thick.
