Description
The PSB Speakers IW SUB28 is a high‑performance in‑wall passive subwoofer designed to deliver deep, authoritative bass while remaining completely hidden from view.
Created for custom installations where aesthetics are just as important as sound quality, the IW SUB28 seamlessly integrates into walls to provide a cinematic low‑frequency foundation without occupying valuable floor space.
Engineered using PSB’s decades‑long expertise in acoustic research and speaker design, the IW SUB28 features dual high‑excursion woofers mounted in a rigid, acoustically optimised enclosure. This design allows it to move serious air while maintaining tight control and low distortion, resulting in bass that is powerful, articulate, and musically accurate.
When paired with PSB’s dedicated subwoofer amplifiers, the IW SUB28 delivers room‑filling impact for movies, television, and music alike. Explosions hit with authority, soundtracks gain scale and depth, and music benefits from a solid, well‑anchored low‑end presence — all without drawing attention to the source.
Designed for seamless architectural integration, the in‑wall format allows the subwoofer to disappear completely behind a paintable grille, preserving clean sightlines and modern interior design. Whether used in a luxury home‑theatre, media room, or whole‑home audio system, the PSB IW SUB28 delivers uncompromising bass performance in a discreet, installer‑friendly solution.
