Features:
The CM 611 Flush Mount Ceiling loudspeaker is designed for low ceiling applications in a public address system. The unit consists of a 160 mm dynamic full range loudspeaker driver, capable of delivering up to 102 dB of Sound Pressure Level (SPL). Coupled with the unit's frequency response of 64 Hz ~ 20 kHz, it gives the unit excellent speech and music reproduction properties.
The unit's built-in line matching transformer makes it suitable for a 70V and 100V distributed speaker system. Multiple power tappings on the transformer allows for outputs of 10, 5 and 2.5 W (100V line system) / 5, 2.5 and 1.3 W (70V line system).
The loudspeaker driver unit is mounted onto an aesthetically pleasing 200 mm circular metal grille finished with a matted surface in Pure White. The whole unit is spring mounted to the ceiling board without any visible screw mounting holes and more importantly without any hassle.
There is also a back enclosure model available (CM 611E). With the metal back enclosure, crosstalk within the ceiling cavity can be prevented while acoustic damping material lining the enclosure reduces echoing.
