In-ceiling placement
The surround speakers should be placed above the listener's ear, about 160cm - 200cm.
Try avoid to place the surround speakers too far behind the listening area, this may
degrade the immersive sound effect. Ceiling mounted in-ceiling speakers can be used for
multichannel systems (6.1 or 7.1) or systems using Dolby Atmos® technology to produce a
vertical sound image. When installing the speakers on the ceiling, place them around 90 -
100 cm behind the listening position, and space them about 100 - 300 cm apart.
Caution : An amplifier able to decoding Dolby Atmos® information is essential for proper
speaker operation. Contact your dealer for more information.
