Features

Designed to Fit Naturally
Design 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. Learn more about Planar wall installation.

Boundary-Coupled Bass
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. A specially tuned 10" passive radiator fires toward the wall behind Planar, using boundary effect coupling to reinforce and expand low-frequency output. With over 45mm of excursion, the passive radiator works in close relationship with the wall surface to produce surprisingly deep bass and remarkable scale from a cabinet only inches deep. The result is immersive, room-filling performance from a form designed to integrate gracefully into real living spaces.

Filtered to Perfection
PL-1 is powered by a 300-watt Pure Class D amplifier engineered to deliver fast dynamics and exceptional control from an ultra-thin platform. Proven across thousands of REL subwoofers, this latest generation design combines high current delivery with long-term reliability, allowing PL-1 to produce deep, articulate bass with remarkable composure. Conservatively rated at 300 watts, the amplifier delivers substantially greater real-world output under demanding conditions. The result is effortless performance for both music and theater systems while remaining efficient, cool-running, and dependable over years of use. REL’s fully analog input filters play a critical role in Planar PL-1’s natural and cohesive sound. By avoiding unnecessary digital processing, PL-1 preserves timing, tonal balance, and the sense of musical flow that allows bass to integrate seamlessly into the system. REL’s renowned High Level Connection allows Planar to receive the same signal fed to your main speakers, creating a unified presentation that feels connected and effortless. Combined with our all-analog PerfectFilter circuitry, PL-1 delivers deep, controlled bass with exceptional speed and clarity.
Wireless Freedom Included
Wireless Unlike traditional subwoofers that require long visible cable runs, Planar PL-1 includes Airship Direct wireless technology as a fully integrated part of the design. By eliminating the need for signal cables, PL-1 preserves the openness and simplicity of modern living spaces while maintaining the speed, dynamics, and musicality expected from a REL. The compact receiver integrates directly into a concealed rear-panel compartment and arrives pre-paired from the factory for effortless setup. No apps. No software updates. No complicated configuration. Simply connect power, position Planar, and experience true REL performance with the freedom of uncompromised wireless operation.
