The IWSub Reference is a completely self enclosed in-wall subwoofer for use in whole house distributed music or “stealth” home theater installations. It’s a deep bass powerhouse that will disappear in your room. It has a non-resonant sealed medite (a dense wood product) enclosure and a paintable bezel and grille. Inside the completely self-enclosed in-wall sub is the technical brainpower derived from Definitive’s award winning SuperCube free-standing subwoofers. It includes a special shallow-depth, long excursion active 13" driver pressure-coupled to a 13" Ultra Low Bass radiator for a total bass radiating surface area of over 265 square inches—more than an 18 inch woofer but with greater speed and control. Combined, these features result in tight musical excellence.

The IWSub Reference In-Wall installation is straightforward and easy in both newly constructed and existing walls. The IWSub Reference must be used with the companion outboard SubAmp 600 (sold separately)which provides 600 Watts of digital power along with sophisticated crossover functions.

The performance of the IWSub Reference goes well beyond the output level, impact and low frequency limits of even its superb smaller cousin the IWSub 10/10, while maintaining its fast, tight musical quality. The Reference produces musically accurate low end that’s never before been available in a compact, nearly invisible in-wall subwoofer that installs easily in new construction or existing walls. The IWSub Reference will deliver superb output performance when used singly, or in pairs for larger rooms.
