The CX 815 and CX 815E Flush Mount 2-Way Coaxial Ceiling Loudspeaker are designed for high ceiling applications in a public address system where directive sound projection is required. The unit consists of a 200 mm 2-way coaxial loudspeaker driver, capable of delivering up to 106 dB of Sound Pressure Level (SPL) and providing excellent speech and music reproduction properties.

The unit's built-in line matching transformer makes it suitable for 70 V and 100 V distributed speaker system. Multiple power tappings on the transformer allows for outputs of 15, 7.5 and 3.8 W (100 V line system) or 7.5, 3.8 and 1.9 W (70 V line system).

The loudspeaker driver unit is mounted onto an aesthetically pleasing 275 mm circular ABS grille finished with a matted surface in Pure White (RAL 9010) and covered with a fine metal mesh. The whole unit is clamp mounted to the ceiling board without any visible screw mounting holes.

The CX 815E features a metal back enclosure which helps eliminate crosstalk within the ceiling cavity while acoustic damping material lining the enclosure reduces echoing.
