The IWTS-28 SUB is an in-wall subwoofer that uses dual heavy-duty 8 in. woofers to deliver rich, vibrant bass to cusom-installed audio systems. It is easily retro-fitted to existing construction using Atlantic's GFR-626 grille/frame assembly, the same grille/frame assembly used for several other Atlantic speaker systems: the IWCB-626, the IWCB-727 THX Select 2, and the IWTS-30 LCR THX Ultra 2.
