REL Planar PL-2 Powered Subwoofer 
 

Maximum Performance. Minimal Space
PL-2 is REL’s solution for spaces where traditional subwoofers do not fit. Designed to work in close relationship with the wall behind it, Planar uses boundary effect coupling to deliver deep, room-filling bass and remarkable scale from an ultra-thin form that occupies little-to-no floor space.

Deep Bass, Minimal Space
REL Performance in an Ultra-thin Form
Traditional subwoofers often demand significant floor space to produce deep, powerful bass. PL-2 takes a different approach. By working in close relationship with the wall behind it, Planar uses boundary effect coupling to make the wall 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 Cart, PL-2 delivers powerful, immersive performance for modern rooms and open living spaces where traditional subwoofers struggle to integrate gracefully. To learn more, visit the Planar Wall Installation Guide
 
Designed for Modern Living
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.
