Height Speakers;
Dolby Enabled Speakers
(Dolby Speakers)
These are types of height speakers. Dolby enabled
speakers are special speakers designed to face the
ceiling so that sound is heard after bouncing off the ceiling
so that sound appears to be coming from overhead.
Furthermore, by installing height speakers, you can select
the Dolby Atmos listening mode, which realizes the most
up-to-date 3D sound including overhead sounds, when
the input format is Dolby Atmos.
Place them either above the front speakers or above the
surround speakers or surround back speakers. Note that
with height speakers you can install up to two sets; Height
1 Speaker and Height 2 Speaker.
