introduction

Congratulations, and thank you for purchasing an a/d/s/ Compact Monitor speaker system. These
loudspeakers offer the perfect combination of style and performance for your audio or home
theater system. Building on the legacy of the original CM series loudspeakers, these high
performance 2-way systems are voiced to be perfect complements to the renowned a/d/s/ C­series in-wall and in-ceiling speakers, as well as our all-new C-series powered subwoofers. Fully
integrated high performance system design has never been easier.

Be sure to save your sales receipt. It is your best record of the date of purchase, which is required
for warranty service.

Read and follow all cautions, warnings and notes.

cautions

To reduce the risk of electric shock, do not remove any parts of the speaker. There are no user
serviceable parts inside. If service is required have it performed by a qualified service
professional.

WARNING
To prevent fire or shock hazard, do not expose the speakers to rain or submerge in water. The
speakers should be situated away from heat sources such as radiators, heat registers, stoves or
other heat sources. Be sure all the components in the system are turned off while making audio
and power connections.

speaker placement

Where you locate the speakers in the room plays a vital role in the sound quality you will enjoy. Since every
room is a little different, you should experiment with various locations to see which gives the best sound
in your particular application. Here are some general guidelines to help you select appropriate locations.

In general, your speakers will have the smoothest response and best imaging when located at least two
to four feet from the back and side walls in the listening room. Moving a speaker closer to one or more
of the boundaries will increase the bass output. In some rooms, the extra bass may sound good while in
others it may cause the bass to sound too strong.

Hard surfaces near a speaker can affect the distribution of high frequencies. Think of a hard wall as if it
is a mirror. Just as a mirror will reflect a nearby object so that you see a second "virtual" object, a hard
wall will reflect sound so that you hear a second "virtual" source of the sound. If the reflected sound is
strong enough it will confuse the imaging of the system. If the speakers are placed near side walls, try
toeing the speakers towards the center of the room. Drapes or cloth hangings on nearby walls will help
to cut down undesired reflections. Drapes are particularly helpful if the speaker is adjacent to windows or
glass doors.

center channel

The CM250LCR is normally positioned on its side, and functions as an accurate and exceptional center
channel speaker. The CM250LCR may be placed either above or below a video monitor when using a
direct view or rear projection set. The CM250LCR may also be used by positioning it vertically, which is
the recommended orientation for optimum horizontal dispersion. With front projection video monitors,
the center channel is commonly placed below the screen. Alternatively, by using an acoustically
transparent perforated screen it may be placed in a vertical orientation, directly behind the screen for
optimum imaging.

main speaker separation

A good rule of thumb is to start by arranging your preferred listening position and the left and right
speakers positions, such that they represent the points of an equilateral triangle. You should then
experiment by varying the separation and the horizontal angle of the speakers until you reach the sonic
sound stage that you prefer.

Although all of the CM series speakers are video shielded, placing them next to a TV monitor will not
typically give adequate separation. When possible, move the speakers a few feet away from either side of
the monitor. Also, when the center channel speaker is used, the left and right speakers should be located
so they are approximately the same distance from the listening position as the center channel. If they are
too far forward, you will lose integrity of the center image. If they are too far away, separation and image
width will suffer.
