Sound Acoustics Ceiling and In-wall Speakers
Sound Acoustics in-ceiling spea ers bring high fidelity music reproduction to a variety of architectural
spaces. They mount flush to walls, ceilings, and virtually any flat surfaces. Installation is quic and simple,
whether in existing buildings or new construction.
Sound Acoustics flush mount spea ers will fit unobtrusively into any space and are ideal for audio-video
surround sound use. Manufactured with water-resistant components, these spea ers may be installed in
high humidity environments such as itchens, bathrooms, and even boats. Best of all, no matter where
you place them, Sound Acoustics in-ceiling and in-wall spea ers ta e up absolutely no shelf or floor
space.
Sound Acoustics in-ceiling and in-wall spea ers are high performance two-way systems. Their woofers
have been specially designed to provide full bass performance without the need for a special enclosure.
The dome tweeter with neodymium magnet is of a quality not normally found in built-in spea ers. As a
result, these spea ers’ sonic performance belies their small size and inconspicuous appearance. As with all
Sound Acoustics high fidelity spea ers, frequency response is smooth and accurate and stereo imaging is
lifeli e.
Some of our ceiling spea ers include full frequency transformers for constant voltage bac ground music
and paging systems with selectable wattage taps and a transformer bypass.
The clean contoured grilles and trim are finished in matte white. If desired, they can be painted any color
to match or complement any interior.
Speaker Placement
Placement of the in-wall or ceiling spea ers in your room should be carefully considered. They should be
located where they will provide you with the best possible sound. It is beyond the scope of this guide to
discuss all of the various aspects of spea er placement. Please feel free to contact your Sound Acoustics
dealer for guidance.
Wiring
To achieve maximum performance from your Sound Acoustics spea ers, we strongly suggest the use of
low inductance, copper stranded spea er cable. For runs over 50 feet 12 or 14 gauge wire must be used,
to prevent signal degradation. It is important to consult and observe any local building codes and
requirements when installing your spea ers and/or running wire through your house.
Installation Tips
1. Avoid routing spea er cables near or parallel to electrical cables. This will help to reduce hum and RF
interference.
2. When securing your wire, do not staple or nail it, a short circuit could occur, which would significantly
reduce your system’s performance, potentially damaging your amplifier/receiver.
3. Allow an additional 2-1/2 feet of free wire at the rough-in brac et or spea er cut-out hole.
4. More than two pairs of these spea ers may be connected to one amplifier, however when doing so we

suggest that a Sound Acoustics load center or impedance matching volume control is used, to prevent
overloading your receiver/amplifier.
5. When connecting the wire to your spea ers, the same wire which is connected to the positive terminal
of the amplifier must be connected to the positive terminal of the spea ers. It is important to chec
this on all spea ers. If one spea er is connected incorrectly, or is “out of phase”, the sound quality
will be seriously impaired.
Step-by-step Speaker Installation Instructions
1. The spea er cut-out must be at least 2” from adjoining walls, ceiling, internal studs and pipes.
2. Hold the supplied template in your preferred location and trace around it. This is the exact cutout
size.
3. Cut the hole with the appropriate tool for your wall or ceiling material.
4. Follow the spea er connection directions included with your amplifier or receiver. Strip 1/2” of
insulation from each of the spea er wires to expose the bare metal and twist each into a single
strand. Connect “+” to the RED terminal on both the spea er* and amplifier, and the “-” to the
BLACK terminal on both the spea er and amplifier.
*When connecting to the 70 volt transformer, connect the “+” wire to the 2.5w, 5w, or 10w wattage
tap, or by-pass the transformer by connecting it to the 8 ohm wire.
5. It is possible to paint the spea er grill and frame to match the wall or ceiling before mounting.
Remove the foam, found under the grill, after the paint is dry.
6. After insuring that the rotating clamps are flipped inwards, place the spea er into the cutout in the
wall or ceiling. Tighten the mounting screws using a power screwdriver or Phillips screwdriver, ta ing
care not to over tighten. This will rotate the clamps, securing the spea er to the wall or ceiling.
7. Install the grill on the spea er.
8. When removing the grill, do not use a nife to pry between the grill and the spea er frame. Instead,
insert a pointed metal tool into one of the grille perforations near the edge and lift the grill free.
