Triad's new FlexSub line allows you to add bass to an audio system with the very least amount of visual impact. We named them “FlexSub” because of their installation flexibility. The Mini FlexSub is a version of Triad's Mini Sub that has been configured to install behind a ceiling, cabinet toekick, baseboard, wall, or crawl space. The bass is channeled through a damped, coiled, expandable, flexible tube that terminates with one of two grills; a very small standard Triad grill, or a Vent Outlet. If you have access to your attic, basement, crawl space, or the back of a cabinet, the Mini FlexSub enclosure mounts in a hidden area, and all that is seen is a very small grill or vent, which we can paint match for you. All parts and hardware are included.
