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
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.
