Thank you for purchasing Atlantic Technology products. Our speaker systems have been designed to deliver exceptional sound and value. We hope
you like what you hear from them, and are happy with your decision to
buy them.
Please take a few moments to read these instructions. They’re intended not
only to tell you how to mount the speakers, but how to get the best performance from them.
Speaker Placement
Instruction Manual
Important Considerations Before
Installation
Recommended Wire Sizes
The longer the wire run, the heavier the wire should be. Use the following
recommendations as a guide for your installation. And if you’re in doubt,
remember that it never hurts to get the next heavier grade of wire. Also note
that lower gauge numbers equal heavier wire sizes.
Wire Run Wire Gauge:
<15 ft. 16 ga.
15 to 30 ft. 14 ga.
>30 to 50 ft. 12 ga.
Location Considerations
A major determinant of any speaker’s sound quality is its location in the
room. With in-wall speakers there are fewer placement options than with
free-standing speakers, so giving some thought to location can really pay
off. Our In-Wall Theater Systems have been designed to minimize the detrimental effects wall mounting can have on sound, so they sound better
than conventional in-wall speakers.
Room Acoustics
Hard surfaces create lots of sound reflections in the room while soft surfaces
tend to absorb sound. Note the speakers’ location in terms of proximity to
glass and other highly sound reflective or absorptive surfaces. A simple set
of curtains or an area rug can make a major difference in sound quality and
intelligibility by reducing excessive reflections.
The more similar the speaker’s surroundings, the more consistent the sound
will be. So placing one speaker directly adjacent to a glass wall, with the
other speaker by an open archway, will make for two dramatically different sounding speakers.
Note that as bass frequencies reflect within the room, some locations may
be bass heavy while other areas may be bass shy. With an external subwoofer, changing its placement within the room may reduce these effects.
But when in-wall speakers are utilized full range, the only real option is to
change the listening position, if you end up in a difficult bass area.
3
Speaker Placement
For all the following situations, it’s recommended that you first place small
box speakers in the proposed locations, just to get a good idea of how
that location will sound. In-wall speakers are tough to move once they’re
installed!
Stereo Music Listening
For stereo music reproduction the speakers are best located at approximately ear level when seated, both on the same wall, facing the prime listening location. A separation of approximately six to eight feet between the
left and right speakers is usually good. Ideally, the distance between the
two speakers will be the same as the distance from the speakers to the listening position. The speakers and the listening position will then form an
equilateral triangle. There is a benefit to mounting the speakers approximately the same distance from the side walls, so they both create the same
reflective patterns.

placement is
dependent on room
size and shape.
Experiment to find a
location that
produces the
smoothest response.
Today’s home theater systems require you to place six or
more speakers in your room. For the most convincing
theater effects, speaker placement must be very carefully
thought out. This is especially true with in-wall speakers,
since their installation is permanent!
Left/Center/Right Locations The tweeter in the front three
speakers should be at or just above ear height when seated,
just as with stereo speakers. Try to keep the vertical position
of the three front speakers within 18 inches of each other, as
this will maintain smooth, believable left-center-right pans.
Optional Direct Radiator Speakers
should be placed slightly behind the
listening position, above ear level.

Back
Optional Surround Back Speakers
should be placed approximately 1-2
feet (.3-.6 meter) above the listener’s
ear level. Bipole or direct radiators
may be used here.
The spacing of the left-right speakers can be a little wider
than with 2-channel stereo speakers, since in a theater system, the center channel speaker reproduces the on-screen
effects and anchors the center image. Left-right spacing of
about 8 to10 feet usually works well.
Surround Speakers In order to achieve optimum performance we strongly recommend Atlantic Technology Dipole
or TriVector™ surround speakers. If you are using our dedicated surround speakers please follow the placement recommendations included in their installation instructions.
Non-Dipole Surrounds The most realistic surround effects
occur when the listener can’t localize the actual location of
the surround speaker. If you decide to use the In-Wall Theater System speakers as surround speakers, mount them
above the listeners’ ears, slightly behind the listening area
either on the side or rear walls.
Mounting the IWTS Speakers
NOTE: We always recommend a professional be involved in the
installation of IWTS speakers.
The IWTS speaker can be easily mounted in most any standard wall material, from ½ to 1½ inches thick. Its rotating wall clamps (sometimes called
"dog legs") firmly fix it to the wall surface after the proper cutout has been
made. Here are some important precautions to take before mounting:
5
Mounting
Instruction Manual
As always, take care to wire the speakers properly, with the positive lead
(normally marked with a red terminal or a “+” sign) from the amplifier connected to the positive terminal on the speakers and the negative
(marked with a black terminal or a “-” sign) connected to its respective
terminals.
Proportions illustrated are for 16"
on-center 2" X 4" stud installation.
See table below for proper dimensions.
Keep the sides of the actual mounting hole at least ½ inch away from
beams or studs to ensure that the clamps have adequate room to rotate.
A stud or other obstruction that’s too close will stop them from properly
doing their job.

Wall cavity size will affect the bass and midrange performance of any
in-wall speaker. The IWTS-5 LCR is designed to play optimally in a 0.5
to 1.0 cubic foot space (measured before wall insulation is inserted) and
the IWTS-10 LCR in a 0.75 to 1.5 cubic foot space. Cubic dimensions can
be determined by multiplying the length x width x height of the cavity. A
larger cavity won’t hurt, but a smaller one will negatively impact the bass
and midrange response of the system.
Mounting Hole
Outline
Speaker Frame
Outline
Some of the sound from the speaker will transmit to the space on the other
side of the wall cavity. If this is a major concern, you can build a box within
the wall that provides the required cubic volume. Please note that there is
very little room behind the drivers in a standard “2 x 4” wall cavity (there’s
only 1/4 inch), so the back of any enclosure box must be made from thin
material. Typically then, the back wall material of your enclosure will be
roughly 1/8 to 1/4 inch thick.
For optimum sound we recommend lining the cavity with fiberglass or
polyfill, observing all the relevant precautions and instructions from the
insulation manufacturer. If you have built a back box, you can use common
fiberglass insulation or open cell foam rubber in the enclosure. Be sure to
push the insulation back from the drivers to ensure that it doesn’t get into
the moving cone area.
In-Wall Enclosure Recommendations
Please use this information to construct an in-wall enclosure if you so
desire. Doing so will generally improve the performance and increase the
power handling of the system.
Be sure to line the cavity with insulation, being careful to avoid letting the
insulation touch the backs of the woofer cones. It’s also important to seal the
joints of the enclosure with a high quality non-shrinking caulk.
Be careful to keep the wires from touching the chassis of the drivers or baffle
in such a manner that the wire might vibrate and buzz. You may use nylon
wire ties to keep the wires properly positioned. Such ties are available that
are designed to screw directly to studs making them ideal for this purpose.

Ceiling Mounting
It is especially important when mounting the speaker in a ceiling that you
cover the back of the system with a fiberglass window screening (available
at any home center or hardware store) to keep insulation and other foreign
matter out of the assembly.You also should install safety wires from the rear
of the assembly to a secure mounting place, like adjacent beams or the floor
above, for added security. Should you be installing IWTS speakers in a suspended ceiling, it is imperative to install safety wires from the speaker to the
support structure above, to ensure security under all conditions.

Installation
IWTS-5 LCR & IWTS-10 LCR In-Wall Theater System Speakers
Installation of the IWTS in New
Construction
Installing the Mounting Frame
To re-install the grille later, press it carefully into the appropriate opening in
the frame assembly. Since it’s designed to fit snugly, please take your time
and use care when installing the grille.
The clamping mechanism allows
the wall material to range from
½ to 1½ inches (13 to 38 mm) in
thickness. There must be a minimum depth behind the wall face
of 3 5⁄8” (92 mm). As noted above,
be sure to keep the edges of the
cutout at least ½ inch (13 mm)
away from any stud or obstruction, as the rotating clamps will
not operate properly if you don’t.
Insert the frame into the cutout
and using a level or square carefully align it so it is level. Tighten
the mounting screws, which will
cause the attached clamps to rotate and position themselves properly
behind the wall.
For shipping, the speaker's baffle will be attached to the frame with two
screws. Remove these screws to separate the baffle from the frame. Reserve
the two screws for installation later.
Continue to tighten until the frame is snug in the wall. You want the bezel
to conform to the wallboard, and the frame not to rattle from the speaker’s
vibration, but be very careful not to overtighten the screws.
Cutting the Opening
Painting the Speaker Assembly
Atlantic Technology offers optional new construction brackets (IN-NC5/10LCR) to ease installation in new construction. Instructions for its use
are included with that kit.
Installation of the IWTS in Existing
Construction
Removing and Installing the Grille
Remove the grille from the speaker using an awl or the point of a drywall
screw in a grille opening near one of the grille corners. Slowly pry the grille
out, being careful not to damage the speaker’s frame or its finish.
The white plastic frame and the
metal grille may be left as is, or
painted to match your décor. You
can paint the frame before or after
it is installed in the wall. Spray
painting (using slightly thinned
paint) is the best method to use for
painting the grille. Remove scrim
before painting. After painting the
grille, use air pressure to “blow
out” any grille holes that are filled
in with paint. Replace scrim after
paint is dry.
After determining the best location for the speaker as outlined above, use
the enclosed template to cut the proper size hole.

WARNING: Exercise extreme care before making any wall cuts to
ensure that you will not cut through any wires, pipes, or other items
that may be in the wall. You may sometimes, but not always, be able
to determine the approximate location of wires and pipes by looking
at the locations of nearby outlets and plumbing. But their location or
absence is never an assurance that there is not something within the
wall cavity.

Installing the Speaker Baffle into the Frame
Specifications are those in effect at the time of printing. Atlantic Technology reserves the right
to change specifications or appearance at any time without notice.
Once the frame is mounted in the wall, the speaker simply fits into the
frame. Use the included screws (including two removed earlier) to attach
the baffle to the mounting frame, but be very careful not to overtighten the
screws.
Should you have any questions or problems please feel free to contact us at
781-762-6300 or through our web site, www.atlantictechnology.com.
Front Panel Controls
HF (High Frequency) Level Control
This control adjusts the relative level of high frequency output to compensate for varying room acoustics or placement behind a screen.
“+2” is for absorptive, acoustically “dead” rooms (or
when the speaker is behind a movie screen). Use this
position to increase the HF level and restore the proper
sparkle and liveliness to the sound.
“0” is for rooms of average absorptive characteristics.
“-2“ should be used in rooms that are highly reflective, with hard floors
and exposed windows.
The setting of the HF control is mostly a matter of personal taste, so try it
in all three positions and see which one is preferred.
IR Knockout (IWTS-5 LCR only)
There’s a “knockout” plug in the front baffle. You can identify it by locating
the Atlantic Technology wave logo which is molded into it. If you are using
a multi-room control system, you can install a standard IR receiver in the
knockout hole.
