Construction with Optional Back Box

For new construction,we highly rec- ommend that you use the optional Back Box IN-BOX-155. The Back Box provides the correct acoustic environment for the 155 LCR and ensures its THX-level performance. The rotator clamps (sometimes called "dog legs") will easily grab the combined thickness of 5/8" sheetrock and the 3/8" back box's front panel. The sheetrock must be adhered to the front panel of the back box very solidly and positively.

Use very liberal amounts of a high-quality construction adhesive, such as Liquid Nails, to ensure a secure, vibration-free bond.

Please see the installation instructions that come with the IN-BOX-155 for more details.

Installation of the IWTS-155 in New Construction without Optional Back Box

There may be new construction situations where the Back Box IN-BOX-155 is either not desired or not feasible. For those situa- tions, Atlantic Technology offers an optional Rough-in Frame Kit IN-NC-155 to ease installation in new construction. Instructions for its use are included with this kit. Ask your Atlantic dealer for more details.

Remove the grille from the speaker using an awl or the point of a drywall screw in a grille opening near one of the grille corners.Slowly pry the grille out, being careful not to damage the speaker’s frame or its finish.

To re-install the grille later,press it carefully into the appropriate opening in the frame assembly. Since it’s designed to fit snugly, please take your time and use care when installing the grille.

Cutting the Opening

After determining the best location for the speaker as outlined above, use the enclosed template to cut the proper size hole.

WARNING: Exercise extreme care before making any wall cuts to ensure that you will not cut through any wires, pipes, or other items that may be in the wall. You may sometimes, but not always, be able to determine the approximate location of wires and pipes by looking at the locations of nearby outlets and plumbing. But their location or absence is never an assurance that there is not something within the wall cavity.
