If connecting more than two speakers to one amplifier channel we suggest that you consult a professional for assistance.

When connecting your speakers, make sure

proper polarity (phasing) is maintained. Simply put, this means ensuring the same wire which is connected to the positive terminal of the amplifier has its other end connected to the positive terminal of the speaker. Note: Most manufacturers use red to designate +. If the connections on one of the speakers are reversed, (out of phase) the quality of your bass will be seriously impaired.

INSTALLATION

If the drywall has not yet been installed a Rough-in-Bracket (RIB- LCR) may be used to reserve the speaker location on the wall. The RIB-LCR brackets are available from the distributor or dealer where the speakers were purchased. When the brackets are used the holes are cut when the drywall is installed. The cable can be tied off on the bracket after securing the cable to a nearby joist.

If the drywall is installed and the speaker locations have not yet been established then do so now. Assess the wall for possible concealed obstructions such as wiring, plumbing, etc. Inspect the backside of the wall, the attic, and/or the crawl space if available for clues to possible obstructions. Use inspection holes with inspection tools (camera, mirror, flashlight, etc.) if absolutely necessary. Use a “stud finder” to locate the positions of the studs.

All the speakers are shipped with two different style clamp rings that allow the speaker to be installed immediately next to a stud—items & below.

Once the speaker locations are established use the paper template (the outside of the outer cardboard rectangle) to mark the speaker cut-out. The dimensions for the cut-out are listed in the chart on the previous page. Using the proper tool, cut the appropriate sized hole in the wall. On drywall, clean cuts can be made with a drywall saw.

If the cable has not yet been run, do so now that you have access to the wall’s interior.

To aid in speaker performance, a fibrous material, such as fiberglass or polyester fiber, may be placed behind the speaker. This may also help to reduce unwanted sound from being transmitted into adjoining rooms. If the wall space has blown or loose insulation, it is important to prevent the insulation from

entering the back of the speaker. This can be accomplished by placing a batt of fiberglass insulation over the back of the speaker.

As the diagrams show, the speakers utilize a metal mounting ring which, after tightening with the screws provided, acts as a clamp to hold the speakers in place.

Install the frame and mounting ring assembly by passing the black mounting ring through the cut-out as illustrated in figures 1 & 2. The white frame should fit cleanly, without interference, in the cut- out hole. If the hole is a little small then trim the hole as needed. Lightly tighten the screws to secure the clamp ring against back of the wall. (see fig. 3) Use care not to over-tighten the screws or the frame will become distorted and make it difficult to install the grille.

Pull the end of the cable out of the wall, strip back a section of the jacket as needed, and then expose ½" (13mm) of each conductor. Connect the wire to the terminals on the back of the speaker assembly, observing polarity (+ & -).

Insert the speaker into the frame and install the eight screws. Tighten the screws beginning with the four inner screws followed by the four outer. (see fig. 4) Use care not to over-tighten the screws or it may later become difficult to install the grille. Install the grilles after testing the operation of the speakers. The grilles are installed by gently working the edge of the grille into the frame of the speaker, beginning at one corner and working one or both directions around to an adjacent or opposite corner.

If the speaker frames are to be painted after installation, either remove the speaker baffle assembly or use the paint-mask (the inner cardboard rectangle) to cover the speakers to prevent damage. DO NOT PAINT THE GRILLE AND

FRAME ASSEMBLY TOGETHER. The grille should be painted separately. Use thin coats and thin the paint as necessary to avoid clogging the perforations with excessive
