Item Description

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 such as our SA-180 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"-thich (!) resonant-free MDF baffle, and its audiophile-grade crossover.

Flexibility

The IWTS-28 SUB is an in-wall subwoofer that uses dual 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.The 28 SUB has several features that maximize its flexibility:

As can be expected, the IWTS-28 SUB can be used as the speaker portion of a separately-powered LFE subwoofer in a true 5.1/7.1 system. When used this way, the convenient front-panel switch for the SUB’s crossover would be set to ‘off,’ and the jumpers connecting the two sets of input terminals are left in place. An RCA cable goes from the receiver’s Sub Out jack into a monoblock amplifier (such as Atlantic’s SA-180), and then from the monoblock amp into the 28 SUB. All low-pass/high-pass crossover functions are then handled by the receiver’s bass management system, as when using any powered subwoofer.
