MM-3RDX-120
The MM-3RDX-120 is an adjustable ceiling speaker mount that provides pan, tilt &
roll adjustments. It supports and aims speakers that are equipped with either the 2
X4-1/4 or the 2-3/4” X 5” 4-point mounting pattern.
This model aims speakers from overhead by way of a variety of tube extensions
and ceiling attachments. Ceiling speakers achieve up to 360 degrees of horizontal
pan angle, up to 180 degrees of tilt angle and 180 degrees of roll adjustment.
Tilt adjustments are made at the side of the speaker adapter plate, Pan-adjust-
ments are made at the tube extension coupler
and the roll feature is adjusted between the
mount and the tube extension. The MM-3RDX-18
tube coupler provides a pathway for signal wire
and a safety cable to pass through the tube
extension to the terminal block. This makes for a
clean, safe and predictable method for installing
and aiming ceiling speakers.
