Features:
ABS Back-box for LC1 Speakers
To be used in combination with LC1-speaker and LC1-CMR mounting ring
On top of the mounting ring, provisions are present to “click-on” the optional Back Box. The combination of Mounting Ring and Back Box prevents sound traveling via the ceiling cavity to adjacent areas, and fully protects the loudspeaker from dust, falling objects.
The Back Box has knock?out holes for two grommets (11 mm/0.80 in) and for two cable glands (20.5 mm/ 0.80 in)
