The IWSub 10/10 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 10 inch driver pressure-coupled to a 10 inch Ultra Low Bass radiator for deep, tight, high impact bass. Combined, these features result in tight musical excellence.
