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

(116 dB) for the sound reinforcement and

PA markets.

• One 203 mm (8.0 in) treated fiber driver

and one compression driver with a 25.4 mm

(1 in) exit mounted to a proprietary cast-

aluminum M8

™

baffle and heat sink.

• 95 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 protective

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).

• UL 2043 approval pending.
• Included accessories: Tile bridge,

Euroblock connector & paint mask

/installation aid.

• Optional accessories: Pre-Construc-

tion Bracket

Description

The CM890i is a premium 8.0” 2-way,

in-ceiling, high-efficiency, high-SPL

loudspeaker for distributed or 8 Ohm

applications. The CM890i incorporates

a dedicated 8.0” 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

CM890i also incorporates a 66 Watt trans-

former with a 6-position tap switch and

voice coil/8 Ohm direct position. Mount-

ing hardware and tile-bridge are included

and feature a fast and secure constant-ten-

sion fixed wing mounting system.
