Biamp offers four sizes of Trim Rings (TR) allowing the
Desono CM, C-IC6 and DX ceiling loudspeakers to fit
in existing holes (up to 279 mm [11"]) in the ceiling. The
illustrations shown are typical installations in drywall and
drop ceilings. Please refer to the appropriate Installation
and Operation guide for additional information on
installation methods.
Drywall Ceiling Installation
1. DX & C-IC6: If possible, insert tile rails (and C-Ring)
into the ceiling and center on the opening. Using the
tile rails spreads the weight better. If the ceiling won't
accept a pair of tile rails, or if you are installing a CM
model, a second trim ring can be used above the
drywall to support the loudspeaker. Cut the trim ring
to allow it to t into the hole.
Note: If using DX tile rails/C ring above the ceiling, cut the C-Ring
to allow it to ex enough to turn it in through the ceiling.
2. Flex, insert and turn the C-ring or trim ring (rim up)
to t it above the ceiling. If applicable, attach the
C-ring to the rails. Center the ring in the opening.
3. With the dog ears moved up and rotated in, insert
the loudspeaker up through a trim ring and into the
ceiling.
Note: SPA-TR300 / SPA-TR400 - Insert plugs in the holes in the
trim ring before installing to preserve smooth appearance.

back out and down. Ensure the loudspeaker is

in the top trim ring/C-ring. Set tap setting and install
grille per the model's instructions.
