System 10 InWall Speakers

Installing the Mounting Frame

The clamping mechanism allows the wall material to range from 1/2 to 1 1/2 inches (12 to 38 mm) in thickness. There must be a minimum depth behind the wall face of 3 5/8” (92 mm). As noted above, be sure to keep the edges of the cutout at least 1 inch (25 mm) away from any stud or obstruction, as the rotating clamps will not operate properly if you don’t. The speaker baffle (the part with the drivers mounted in it) is designed to mount into the white frame after the frame is mounted into the wall.

Insert the frame into the cutout and using a level or square carefully align it so it is (or it appears) level. Tighten the mounting screws, which will cause the clamps to rotate and position themselves properly behind the wall, until the frame is just snug in the wall. You want the bezel to conform to the wall board, and the frame not to rattle from the speaker’s vibration but be very careful not to overtighten the screws.

Painting the Speaker Assembly

The white plastic frame of the speaker baffle assembly 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. After painting the grille, use air pressure to “blow out” any grille holes that are covered over with paint.

Speaker Connection and Assembly

Strip about ˚” of insulation from the connecting wires. Connect them to the appropriate push terminal, being careful to observe polarity (positive to the red terminal, negative to the black terminal). Install the speaker baffle assembly into the previously mounted frame assembly, being careful to ensure that the speaker wire isn’t pressed up against the back of a speaker cone, and screw it into place using the supplied screws. Again, be careful not to overtighten the screws. Insert the grille into the frame as outlined above, being careful not to damage the frame or the grille’s finish.

High Frequency Level Control

There is a switch located behind the grille on the front of the speaker. This switch is accessible by removing the grille as outlined above. You can change the switch setting with your fingernail or a small pointed object, such as a ball point pen. The switch has three settings that adjust the high frequency output from the speaker. We strongly recommend that you try all three settings, using both music and movies (if the System 10 LCR is part of a home theater system). Please note that recordings vary in their sound balance so try several different discs. Try to achieve the best balance of natural overall sound with good detail and clarity. The switch settings are “Normal” in the lower position, “-2dB” in the middle position, and “+2dB” in the upper position. To aim the tweeter, press gently on the plastic ring that surrounds the dome, but not the dome itself. Aim the tweeter at the prime listening position when the LCR is used as a front speaker, and away from the listening position if it’s used as a surround.

Installation of System 10 SR Dipole Surround

IMPORTANT: Note that the Installation Bracket is required for all installations, new construction or retrofit. Please see the installation instructions for the IN-INST-20SR for information pertaining to Installation Bracket mounting, and its use as a rough-in assembly in new construction. The following instructions primarily apply to the final installation of the speaker system into the already mounted Installation Bracket.

The following instructions cover only the System 10 SR.When the Installation Bracket has been used as a rough-in device in new construction, proceed directly to Step 4.

Cutting the Opening - Installing the Installation Bracket

After determining the best location for the speaker as outlined above, use the template (enclosed in the Installation Bracket kit) to cut the proper size hole. (System 10 SR - 11” x 14 3/8”, “landscape” orientation)It’s. very important to cut the hole level as there is no “play” between the speaker and the Installation Bracket.

IMPORTANT: 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 presence or absence is never an assurance that there is not something within the wall cavity.
