REL PL-1 Planar Subwoofer

REL Planar PL-1

REL Planar PL-1 is an ultra-thin powered subwoofer engineered to deliver deep, articulate bass in smaller to medium-sized rooms without dominating the space. Designed for near-wall or on-wall installation, it uses boundary effect coupling, dual 6.5-inch long-throw active drivers, and a 10-inch rear passive radiator to produce fast, controlled low-frequency performance with the natural musicality REL is known for. The built-in AirShip Direct wireless system keeps installation clean and flexible, while the slim gloss black cabinet with included cloth grille blends elegantly into modern living spaces.
