CM890i
  • General
  • Feature
  • Specification
The CM890i is a premium 8.0” 2-way, in-ceiling, high-e ciency, high-SPL loudspeaker for distrib- uted or 8 Ohm applications. The CM890i incorpo- rates an 8.0” treated ber 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 transformer with a 6-position tap switch and voice coil/8 Ohm direct position. Mounting hardware,support cable, and tile-bridge are included and feature a fast and secure constant tension
