Meet the D3is

The Perlisten D3is In-Wall/On-Wall Subwoofer With Amplifier is designed for high-performance bass where depth and discretion matter. Its ultra-slim enclosure is built to mount in-wall or on-wall, making it ideal for dedicated theaters, media rooms, and modern living spaces where floor space is at a premium. Inside the enclosure are three long-throw 8.5" carbon-fiber drivers, engineered for speed, control, and serious low-frequency output.

Power and processing are handled by the included external DSP-controlled 1500W RMS amplifier. This approach keeps the in-wall/on-wall enclosure slim while placing system control, EQ, and connections in a rack-friendly chassis.
