Congratulations on your purchase of the
AudioSource AE515 MTM In-Wall Cinema Speaker.
This product is designed to reproduce the audio
portion of your home entertainment environment
with accuracy and detail that will satisfy the most
discriminating listener.
Please read this Installation Manual to ensure the
proper installation and performance of your AE515
speaker.
Preparing for your Installation
Gather the necessary tools for your installation.
You will need the following tools:
1) A Keyhole or Drywall Saw
2) A Phillips Screwdriver
3) Masking Tape
4) A Pencil
5) A Bubble or Laser Level
6) A Tape Measure
7) A Stud Finder (recommended)
8) Your AE515 Speaker
Placement
Plan your speaker placement carefully. Make certain
that electrical, plumbing and any other services will not
interfere within the walls where you plan to install your
speakers. The AE515 speaker can be mounted in
ceilings, but is typically used in walls in a stereo pair,
singly as a center channel, or in Left/Center/Right
configuration (See Figure 1). The speakers should
be located so that they provide even coverage at your
listening position. The distance between the speakers
should not be greater than the distance from the
speakers to the listening position (See Figure 2).
If the room’s dimensions or furniture placement prevent
adhering to this requirement, the tweeters in the
AE515 speakers can be swiveled to aim them at the
desired listening position. Speaker height should be
maintained at ear level or just above. Again, the
tweeters may be aimed into the listening area.
New Construction
If you are installing your speakers in new construction
before the finished walls go up, AudioSource offers
New Construction Brackets, which provide a stable
frame that can be fastened to the wall studs on 16”
or 24” centers. This allows the sheet rock or other
wall covering to be installed and provides a template
to cut the opening for the AE515 speaker.
AE515
In most modern buildings the wall studs are positioned
on 16” centers, providing a space between the studs of
approximately 14 3/8”. The AE515 requires a hole size
of 13-15/16” x 6-7/8” (354x175mm). Additionally, you
should allow an extra 3/4” along the long sides of the
AE515 behind the wall surface to allow room for the
screw clamps that mount the speaker to the wall to
swing into position.
Use a stud finder to locate the vertical studs behind
the wall surface . Also, you should now check fo r
obstructions like cross bracing above and below the
desired speaker location.

After selecting the mounting location, mark the hole to
be cut out. A template is provided in the speaker box.
Locate and level the template, then mark with pencil on
the wall surface. If you are unsure whether there are
obstructions behind the wall surface where the speakers
are to be mounted, cut a small hole in the center of your
marked mounting location. Holding your drywall saw at a
45 degree angle (see Figure 3), cut a square hole that
you can use to find any obstructions, should they exist.

The 45 degree wedge shape of the removed surfacing
material w ill make replacement, if necessary, a much
easier task and yield a better finish when patching the
work.
Once it has been determined that there are no obstructions, cut the hole to mount the speaker using the drywall
saw at a 90 degree angle to the wall surface. Cover the
raw edges of the wallb oard with mas king tape (Se e
Figur e 4). This will preve nt th e bac k pressure of th e
speaker from blowing loose gypsum dust out and onto
the painted wall surface after installation. Do not allow
the tape to extend more than 1/4” beyond the edge of
the ho le into the room. Th e frame of the speaker will
cover and hide the tape.
If you are uncomfortable with running the speaker wire
yourself in existing construction, it is recommended that
you retain a qualified custom home installation specialist
or electrician.
Installing the Speakers
Installation Tip! To further enhance the performance
of your AE 515 sp eake r, the wall c avi ty wher e y ou
plan to pl ace y ou r s pe ake r can b e s tu ffe d wit h a
generous quantity of fiberglass insulation. Stuff the area
abov e and und er th e speaker opening with 6” t hick
insulation to a depth of approximately 2 feet beginning
1 foot above and 1 foot below the speaker opening. If
the insulation is foil or paper backed, face the backing
away from the AE51 5 speaker . The add ition of this
insulation will help prevent unwanted transfer of sound
into the otherwise large and resonant cavity of the uninsulated wall.

It is now time to connect the speaker wire to the speaker.
Your s peaker wire is usually coded to identify each
conductor as either positive or negative. This can be
by color coding, or one conductor may have a printed
marking or at least a rib along one edge that you will not
find on the other. Identify which type of polarity coding
that your wire is using. You must carefully observe that
the p ositive terminal of the speaker ou tput o n your
amplifier is connected to the positive terminal of the
AE515 speaker. Likewise, the negative terminal of the
amplifier’s speaker output should be connected to the
negative terminal of the AE515 speaker (Figure 6).

Next run your speaker wire to your speaker locations.
A UL ra ted CL3 speaker w ire is r ecommended when
runnin g wire inside your walls. In many areas it may
be required by code. When running your speaker wire
you should avoid having the speaker wire run parallel
to the 120V p ower lines to avert picking up hum and
inte rfer ence fro m the pow er s ervi ce. If t he speake r
wire needs to cross a 120V power line at a right angle
this is acceptable and will not create a problem.
The clamp screws contact the inner surface of the grill,
pushing it gently out of its mounting groove (Figure 5).
Only lift the grill 1/4" (6mm) at this location. Next use the
other mounting clamps to further loosen the grill. Use
care to not distort the grill shape.

Grill Removal for Installation
CAUTION! The grill is held in place by contact pressure
around the edges where it attaches to the speaker frame.
To avoid difficulty reinstalling the grill, care should be
taken to not distort its shape while removing it.
