Biamp Desono CM60DTD Two-Way 6.5-Inch Ceiling Loudspeaker

The Desono CM60DTD two-way 6.5″
ceiling loudspeaker delivers crystal clear
audio for all your public address and
background music needs. Its 6.5” coated
paper woofer and 1” tweeter results in a
high SPL and extremely low distortion,
ensuring exceptional clarity over the entire
frequency spectrum.
The CM60DTD utilizes a 5-position
switchable transformer ranging from
3.75W to 60W with low-impedance
bypass for constant-voltage operation,
making it an excellent choice for large
areas of BGM.
Designed with the installer in mind, they
can be blind-mounted from below the
ceiling, and feature a magnetic grille for
easy toolless installation and removal
that can also be painted to match the
room decor. Additionally, the tap switch
is located on the face of the loudspeaker,
so adjustments can be made without
requiring ceiling access.
Desono CM60DTD loudspeakers are
an ideal choice for a multitude of
environments that demand superior
speech intelligibility and full range music
reproduction.
