Broad-bass Technology13" In-wall Driver
The IW Sub Reference includes a special shallow-depth, long-excursion active 13" driver pressure-coupled to its Ultra-Low Bass Radiator to produce deep, formidible bass.
Ultra-low Bass Radiator
The active 13" woofer and 13" Ultra-Low Bass radiator boast a combined bass radiating surface area of over 265 square inches-more than an 18" woofer but with greater speed and control for tighter, deeper, more powerful bass.
The Subamp 600
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.
Installation Flexibilitycustomize To Your Home
Whether new or existing construction, walls or ceilings, residential or commercial, the IW Sub Reference presents a simple, secure installation. From metal pivoting lock arms to paintable grilles and frames to fully sealed enclosures, Definitive Technology engineers designed speakers that put installation simplicity on equal footing with sound quality.
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.
The IW Sub Reference's grille is paintable, with easy step-by-step instructions.
