The PC-2668 speaker can be mounted (exposed installation) to the ceiling where flush mounting is impossible. It can be easily installed thanks to its spring catch method. Push-in connector allows quick wire connection, and speaker lines can be bridged by bridging terminals. The supplied bracket can be mounted to a flush-mount pull box.
