The SubAmp 600 for real low-end power
The IW Sub Reference is externally powered, so there’s no need for installers to run electrical to the in-wall subwoofers. The outboard SubAmp 600 (required, not included) can power up to two IW Sub Reference subwoofers, even in different rooms.
With this unbeatable combination, installers enjoy the same ease of installation with in-wall subs as they do with in-wall speakers.
Fully Enclosed for powerful sound where you want it
To play bass in the room it’s intended for, rather than spilling into adjacent rooms via walls and ceilings, The IW Sub Reference is fully enclosed and sealed with dense, acoustically inert, anti-resonant, anti-vibration Medite® wood. You’ll hear tight, powerful bass with no distortion or buzzing.
Paintable Grilles for the final custom touch
The IW Sub Reference’s grille is paintable, with easy step-by-step instructions.
