Features

Designed for Modern Living
Design Planar PL-2 was designed to deliver true REL performance from an ultra-thin form that integrates naturally into modern spaces. Its slim proportions, flowing radiused edges, and deep lacquer finishes allow it to occupy spaces where traditional subwoofers often feel intrusive. Every detail was carefully considered, from the recessed controls and concealed cable management to the optional hardwood grille upgrades that further elevate its architectural presence. Available in black or white lacquer finishes, Planar PL-2 combines elegant industrial design with purposeful engineering, creating a subwoofer designed not only to sound extraordinary, but to live beautifully within the room itself. 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.
Flat Piston. Massive Scale
Flat Piston. Massive Scale
Boundary-Coupled Bass
Developed exclusively for Planar, PL-2’s new 8” Flat Piston driver was engineered to deliver remarkable output from an ultra-thin cabinet. Producing deep, powerful bass from a driver barely 80mm deep required an entirely new approach to excursion, rigidity, and control. The result is fast, dynamic bass that extends to 27Hz, reaching more than an octave below the fundamental range of many acoustic instruments while delivering the scale and authority expected from far larger subwoofers. A specially tuned 10” long-stroke passive radiator, featuring a lightweight paper cone reinforced with a rigid aluminum center cap, fires toward the wall behind Planar, using boundary effect coupling to reinforce and expand low-frequency output. Working in close relationship with the wall surface, PL-2 transforms the wall into part of the acoustic system, producing deep, room-filling bass and remarkable scale from an ultra-thin form. The result is bass that feels effortless, expansive, and far larger than the cabinet itself suggests.
Effortless Power, Proven Reliability
Effortless Power, Proven Reliability
Filtered to Perfection
PL-2 is powered by a 550-watt Pure Class D amplifier engineered to deliver effortless 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-2 to produce fast, powerful bass with remarkable composure. Conservatively rated at 500 watts, the amplifier delivers a clean 600 watts on REL’s test bench under demanding conditions. The result is an amplifier capable of delivering the scale and impact demanded by both music and theater while remaining efficient, cool-running, and dependable over years of use. REL’s fully analog input filters are central to Planar’s natural, seamless sound. By avoiding unnecessary digital processing, PL-2 preserves speed, timing, tonal balance, and the organic character that define great music and theater reproduction. At the center is REL’s renowned High Level Connection, allowing Planar to receive the same signal fed to your main speakers for exceptional integration across the entire system. Combined with our all-analog PerfectFilter circuitry, PL-2 delivers deep, extended bass with remarkable clarity, speed, and balance. For dual-use music and theater systems, dedicated High Level and .1/LFE inputs allow both signals to operate simultaneously, preserving musical coherence while delivering the full impact of cinematic low-frequency effects.
Wireless Freedom Included
Wireless Unlike traditional subwoofers that require long visible cable runs, Planar PL-2 includes Airship Direct wireless technology as a fully integrated part of the design. By eliminating the need for signal cables, Planar preserves the openness and visual 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 full-range REL performance with the freedom of uncompromised wireless operation. Just connect power, place it, and experience full-scale REL performance wirelessly.
