The installation ring is designed with features that allow the optional Back Box to be seamlessly attached. This combination of the Mounting Ring and Back Box effectively minimizes sound transmission through ceiling cavities to neighboring spaces and offers comprehensive protection for the loudspeaker against dust and debris. The Back Box is equipped with knock-out openings suitable for two grommets (11 mm/0.80 in) and two cable glands (20.5 mm/0.80 in).
