SPEAKERꢀPLACEMENT  
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.  
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.  
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.  
MOUNTINGꢀSURFACEꢀPREPARATION  
New Construction - Unfinished Ceilings  
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.  
A Pre-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.  
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.  
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.

Ceiling Cut Out  
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.
