NOTE:
Retrofit Back Boxes are available for all in-ceiling Motion series speakers. These back
boxes reduce sound from “leaking” into the area above where the speaker is installed. For
example, if building a home theater downstairs and there are living spaces directly above where
the speakers are installed it may be desirable to use these back boxes to help contain the sound
so it does not cause any disturbance to those above the speakers.
