BS-680FC
Wall Mount Speaker System

The BS-680F/FC speakers have a strong, all-metal body, and are 
ideally suited for emergency broadcasting (voice alarm system) 
applications. 6" (16cm) double cone speaker unit ensures high-
quality sound. They can be quickly and easily installed in either a 
horizontal or a vertical orientation. Either concealed in-wall wiring or 
exposed wiring can be used for speaker cable connection. 

A push-

in type input connector on the BS-680F allows easy cable 
connections and bridge wiring, while on 

 

The BS-680FC provides two ceramic screw terminal blocks 
(1 cable to 1 connection type) allowing bridged connection.
The selectable input impedance can be easily 
adjusted by changing the top position of the unit’s transformer. Both 
wall and in-wall mounting are possible. The innovative structural 
design is based on the Golden Ratio (1: 1.618), and also permits 
direct wall installation with screws, making the speaker unit resistant 
to falling even if outward force is applied to it.

• Innovative design based on the Golden Ratio (1:1.618)
• Quick and easy installation
• Strong all-metal body
• Horizontal / vertical installation 
• Wall / in-wall mounting 
• Ideally suited for emergency broadcasting applications
