Preparation

Accessories that can help

For installation in a drop ceiling (where tile is installed below the ceiling joists), Bose offers an optional Drop Ceiling Kit (Product Code #031355) for two speakers. It protects the tile from bearing the weight of the speakers. Instructions are included with the kit.

For installation in new construction, Bose offers a Rough-in Kit (Product Code #031353) for two speakers. It is designed for use after the studs are in place and before the wallboard is added to reserve a place for the speakers and indicate where the wallboard hole should be made. It also protects the wallboard by providing additional support for the dogleg clamps that secure the speaker to the wall. Instructions are included with the kit.

For more information or to order an accessory, contact your Bose® dealer. Or, to contact Bose directly, refer to the address list included in the carton.

Use special care in cutting through plaster and lath

For wall construction of plaster and lath, use special care to prevent plaster from cracking:

•After you have drawn an outline of the hole to cut, tape around the outline and use a sharp blade to make shallow cuts where the hole will be.

•Then, within the outline only, chip the plaster away until you expose the lath underneath.

•Finally, cut through the lath very carefully. Using an electric sabre saw can be quick but risky. We recommend using a hand saw and proceeding cautiously to avoid damaging the surrounding plaster.

Installing in a pre-wired room

An installation is simplest when the room has been pre-wired during construction. In that case, the builder will have left speaker cord within easy reach of the intended speaker positions.

How to determine pre-wiring

If you are not sure that you have a pre-wired room, or do not know where the wiring is located, check the architectural drawings of your room or call the builder.

CAUTION: It is important to know where the pre-wired cord is to prevent damaging it while drilling or cutting into the wall.

In the ideal situation, after cutting the speaker hole you can simply reach inside to locate the length of cord the builder has installed.

What to do when the room is not pre-wired

In this case, you will need to run speaker cord from the receiver or amplifier through the wall to the area you have chosen for installing the speakers.

If you have not done this before, be sure you understand the steps involved before you get underway. Having a friend who can help with this step is advisable, too.

Information on running speaker cord in new construction is provided in “Before the wallboard goes up,” beginning on page 13.

For running speaker cord inside finished walls, refer to “Where the walls are finished,” begin- ning on page 13.
