SPEAKER PLACEMENT

Before installing your speakers, you should consider their placement carefully, taking into account the location of electrical, plumbing and other fixtures. Contact your Dealer for assistance if you are unsure of the best location for your particular listening environment.

Placement In Ceiling: When placing your speakers into the ceiling, they should ideally be located above the primary lis- tening area. If the speakers are positioned far away from the primary listening area, adjust the pivoting tweeters so they are pointed towards it.

Note: To avoid possible damage to the pivoting tweeters, read the section entitled “SPEAKER ADJUSTMENTS” in this manual prior to performing the tweeter adjustment.

In a very large room with high ceilings, it may be necessary to place additional speakers throughout the room. Contact your Proficient Audio Systems Dealer for assistance.

MOUNTING SURFACE PREPARATION

New Construction - Unfinished Ceilings

APre-Construction Bracket, available from your Dealer, may be installed prior to drywall application across joists (up to 24" on-center) where a speaker will be located. After the hole is cut and the drywall is installed, the speakers are then easily installed following the instructions for mounting in “Finished Ceilings” below. Note: If the speakers are to be mounted more than 24" on-center, a special “Extra Long Wing” is available from your Dealer.

Finished Ceilings

Prior to the actual installation of the speakers, it will be neces- sary to run cables to the speaker locations. See your Dealer for more information about cable installation. After the cable has been properly installed, you are ready to mount the speakers. Following the simple steps listed below will result in a profes- sional looking installation:

1.Determine the best area to mount your speakers. This area of the ceiling should be free of obstructions such as electri- cal conduit, HVAC ducts, or water lines. This can best be determined by noting the placement of fixtures and gaining access to an attic or crawl space for further analysis of the location of such obstacles.

3.Mark the hole. A template for setting the hole is provided in the box (along with two paint mask inserts for use when painting). Position the template in the desired position and pencil an outline on the ceiling.

4.Cutting the hole. CAUTION: This is the most important part of the entire installation. If you are not certain whether any obstructions exist behind the desired mounting area, you should start by cutting a small hole in the center of your penciled mounting hole with a drywall saw, cutting at a 45˚ angle towards the inside of the hole. (See Diagram 1) Cutting the small hole at this angle will make drywall repair much easier, using the piece cut out. Once you have determined that there aren’t any obstructions in your desired mounting location, start cutting the finished hole at a 90˚ angle to the ceiling surface.

2.Find the joists nearest the desired speaker mounting loca- tion. We highly recommend using a good stud-finder tool for this procedure. If you are lining up the speakers to some other object or molding in the room, make sure you con- sider the size of the baffle flange which extends beyond the mounting hole.

5.Add insulation. If the area in the ceiling is not already insulated, add an adequate amount insulation material to loosely cover the back of the speaker. If the insulation mate- rial used is faced with foil or paper, position the foil or paper away from the speaker.
