SPEAKER PLACEMENT
Before installing your speakers, you should consider their

the section entitled “SPEAKER ADJUSTMENTS” in this manual
prior to performing the tweeter adjustment.
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.
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
listening area. If the speakers are positioned far away from
the primary listening area, adjust the pivoting tweeters so they
are pointed towards it.
MOUNTING SURFACE PREPARATION
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 deter-
mined 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 professional 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 insu-
lated, add an adequate amount insulation material to loosely
cover the back of the speaker. If the insulation material used
is faced with foil or paper, position the foil or paper away
from the speaker.
