BS-678BSB

Box Speakers

The BS-678BSB is a voice alarm certificated wall speaker. With a high quality sound cone speaker the BS-678BSB is suitable for announcement and music. Either concealed in-wall or open wiring can be used for installation.

The speaker's structure permits direct wall-mounting with screws, which prevents the speaker from falling even if an outward force is applied to it.

The input impedance can be easily changed by changing the tap position of the transformer.
