TOA PC-645R

The PC-645R is a ceiling speaker with the rated input of 6 W (when connected to the 100 V line). It fits in the mounting hole with diameter of 15 cm and can be mounted to the ceiling by means of screws. The ceiling speaker is designed for operation on both the 70 V and 100 V lines, and the impedance can be changed by changing connector connections to transformer taps. The panel is made extremely thin and is colored in off white, permitting the mounted speaker to look clean.
