Preliminary Technical Information
The information in this document reflects
preliminary data. Items including polar
plots, frequency, phase and impedance
response graphs will be added when final
data are available.
Key Features
• BroadBeamHP® waveguide technology
delivers a consistent dispersion pattern
for maximum coverage area per speaker
(up to 10 kHz, EASE™ documented).
• 66 Watt transformer and high output
(113 dB) for the sound reinforcement
and PA markets.
• One 165 mm (6.5 in) treated fiber driver and
one compression driver with a 25.4 mm
(1 in) exit mounted to a proprietary cast-
aluminum M6™ baffle and heat sink.
• 93 dB Average sensitivity offers high-
output capabilities and reduced amplifi
-
cation costs.
• Separate tool-free magnetic grille &
bezel assembly for ease of install and
in-field painting.
• Iridite-plated, steel grille with protec-
tive powder-coated finish for lasting
durability.
• Rapid-installation blind mount fixed
wing mounting mechanism with con
-
stant tension design affixes to ceiling
thickness tolerances ranging from 6.4
mm (0.25 in) to 42.9 mm (1.69 in).

Bracket & Junction Box.
• High quality black or white paint finish.
Description
The CM690i is a premium 6.5” 2-way,
in-ceiling, high-efficiency, high-SPL
loudspeaker for distributed or 8 Ohm
applications. The CM690i incorporates
a dedicated 6.5” treated fiber driver and
high-power compression transducer with
a BroadBeamHP® waveguide to deliver a
consistent dispersion pattern and superb
intelligibility for the foreground music,
sound reinforcement and PA markets. The
CM690i incorporates a 66 Watt transformer
with a 6-position tap switch and voice
coil/8 Ohm direct position. Mounting
hardware and tile-bridge are included and
feature a fast and secure constant-tension
fixed wing mounting system.
