Powerful in-wall bass that hides from view. The IWTS-28 SUB is an in-wall subwoofer that uses dual heavy-duty 8" woofers to deliver rich, vibrant bass to custom-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. Boasting amazing hookup flexibility, the 28 SUB can either be used passively, driven directly off the receiver's front Left/Right speaker outputs by utilizing the 28 SUB's on-board low-pass crossover, OR it can be driven actively by using a power amplifier connected to the receiver's 'sub out' jack. The 28 SUB's on-board low-pass crossover is then switched to 'off,' and the crossover functions and bass level duties are handled by the system electronics, as with any powered subwoofer. Several design features distinguish 28 SUB's amazing performance--its powerful, long-throw woofers, its solid 1"-thick(!) resonant-free MDF baffle, and its audiophile-grade crossover.
