Find the appropriate place for installation
Note: Carefully choose the place where you want to install your In-Ceiling loudspeaker because any later changes
may result in time-consuming and costly processes.
Tips for finding the best place for your loudspeaker:
* As a general rule, please note, that there should be a distance of 50 cm between the loudspeaker and the corner of a room
(see picture below). If the loudspeaker is installed in a disadvantageous place of a room, the acoustic properties will be
extremely poor.
* If the loudspeaker is going to be used for stereo applications (this requires 2 In-Ceiling loudspeakers), the optimum listening
position should be located in the middle of a stereo triangle. This means in other words, that your listening position will be
located at the top of an imaginary triangle, whereas the two loudspeakers must be installed where you imagine the other
edges of this triangle.
* You have to decide whether you prefer an installation for surround applications or for stereo applications. The installation
for a surround application requires 5 loudspeakers (minimum): main speaker left "L", main speaker right "R", center
loudspeaker "C", rear speaker left "Eff. L" and rear speaker right "Eff. R".
The figures below show the installation for a stereo application and for a surround application. Please refer to the locations
given in this figure.
Detailed information regarding the installation of the loudspeaker and the removal of the front grille and speaker unit can be
found on the following pages.
Note: Before you install the loudspeaker, please make sure, that there are no electrical lines, gas pipes,
water pipes or heating pipes.
