MUSICA In-Wall and In-Ceiling speakers are designed to work within any interior decorating scheme. They can be installed in virtually any location where flush mounting is possible. To maximize their acoustical performance, however, certain guidelines should be followed. For the best stereo reproduction the two loudspeakers should be placed an equal distance from your listening position and separated so that the angle between them, at the listening position, is between 40 and 60 degrees. For best music and home theater imaging, we recommend that the units be placed so that the tweeters are as close as possible to the ear level of a seated listener.
