LOUDSPEAKER PLACEMENT
MTX In-Wall 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 sound performance however certain guidelines should be fol-
lowed. 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 stereo 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. As this is
not always possible in keeping with aesthetic design of a particular room, MTX
In-Wall Speakers were designed with a pivoting tweeter which rotates to allow you
to “aim” the high frequencies toward the listening position.
TWEETER LEVEL ADJUSTMENT
The output of the tweeter can be adjusted to compensate for speaker placement/
listening positions that are less than ideal. The 0dB position is designed to pro-
vide the smoothest frequency response on axis. If the high frequency response is
considered to be too strong or too weak, the tweeter level can increased (+3dB
position) or decreased (-3dB position) to suit the listeners preference.
