Speaker Placement Instruction Manual Location Considerations Choosing the location for the subwoofer is a very important consideration. Since the IWTS-28 SUB can't easily be moved once it’s installed (!), very careful consideration should be given to its placement. In general, the cleanest and most articulate delivery of bass energy into the room occurs when the subwoofer is placed asymmetrically with respect to the room’s dimensions. (see fig. 1).
Connections IWTS-28 SUB In-Wall Subwoofer Connecting the IWTS-28 SUB to Your System To Connect as a Passive Bass Module: The IWTS-28 SUB may be used as a passive bass module to reinforce the bass from the left/right front speakers in your system, or it may be powered by an external amplifier (such as Atlantic’s SA-180 mono bloc amplifier). Remove the jumpers from the 28 SUB’s terminals (see fig. 4).
Installation Instruction Manual Mounting the IWTS-28 SUB NOTE: We always recommend a professional be involved in the installation of IWTS speakers, if at all possible. You will need the Grille/Frame assembly GFR-626, sold separately. The GFR-626 can be easily mounted in most any standard wall material, from ½ to 1½ inches thick. Its rotating wall clamps (sometimes called “dog legs”) firmly fix it to the wall surface after the proper cutout has been made.
Installation IWTS-28 SUB In-Wall Subwoofer Cutting the Opening Painting the Speaker Assembly The white plastic frame and the metal grille may be left as is, or painted to match your décor. You can paint the frame before or after it is installed in the wall. Spray painting (using slightly thinned paint) is the best method to use for painting the grille. Be sure to remove the scrim cloth before painting the grille.
