The BS-680U is a wall-mount speaker constructed with a strong, all-metal cabinet, making it ideal for use in voice alarm systems. It can be surface- or flush-mounted to the wall, with either concealed in-wall wiring or exposed wiring for speaker cable connections. The speaker's direct wall-mounting structure uses screws to help prevent it from falling even when outward force is applied. The input impedance can be easily changed by adjusting the transformer tap position. The built-in 16 cm (6") double cone speaker unit delivers high-quality sound. The push-in type input connector makes cable connections easy and allows bridge wiring. The TOA BS-680U is certified to UL 1480 UUMW and ULC-S541 standards and is intended for indoor use only.
