Constructed with metal cabinet, the speaker is ideal for use in a Voice Evacuation System. The speaker can be surface- or flush- mounted to the wall. Either concealed in-wall wiring or exposed wiring is possible. The input impedance can be easily changed by changing the tap position of the transformer. A built-in 6-inch (16 cm) double cone speaker unit delivers high quality sound. Two ceramic screw terminal blocks (1 cable to 1 connection type) make bridge connection easier.

The BS-680FC is certified with EN 54-24.

The BS-678B, is made of wood and can be installed in a vertical or horizontal orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer. Two built-in 6-inch double cone speaker units deliver high quality sound. The push-in type input connector makes cable connections easy and allows bridge wiring. BS-678B have a built-in attenuator and can be connected to a 2-wire or 3-wire system.

The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer. Two built-in 6-inch (16 cm) double cone speaker units deliver high quality sound. The push-in type input connector makes cable connections easy and allows bridge wiring. BS-678BT have a built-in attenuator and can be connected to a 2-wire or 3-wire system.

The BS-678T, is made of wood and be installed in a vertical or horizontal orientation. Either concealed in-wall wiring or exposed wiring can be used for speaker cable connection. The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied to. The input impedance can be easily changed by changing the tap position of the transformer. Two built-in 6-inch (16 cm) double cone speaker units deliver high quality sound. The push-in type input connector makes cable connections easy and allows bridge wiring. BS-678T have a built-in attenuator and can be connected to a 2-wire or 3-wire system.

The BS-680F speaker has a strong, all-metal body, and is ideally suited for emergency broadcasting (voice alarm system) applications. The 6" (16cm) double cone speaker unit ensures highquality sound. It 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 allows easy cable connections and bridge wiring. 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.

The BS-634 and BS-634T are wall-mount speakers matched with a supplied plug-in speaker receptacle, for easy installation. The 6W
rated input BS-634/634T are 5" (12cm) cone-type speakers. An M4 screw terminal input connector allows easy connections. The speakers are driven on a high-impedance (100V or 70V) line, with rated inputs. A selectable attenuation function is provided on the BS-634T. The speaker enclosure’s design proportions are based on the Golden Ratio (1: 1.618). A low profile blends in well with room décor. Both vertical and horizontal installations are possible.Enclosure and grille net colour is off-white.

The BS-1034 and BS-1034S are wall-mount speakers matched with a supplied plug-in speaker bracket, for easy installation. The BS-1034/1034S combine a low-frequency 5" (12cm) cone-type speaker and a high-frequency balanced dome-type speaker. An M4 screw terminal input connector allows easy connections. The speakers are driven on a high-impedance (100V or 70V) line, with rated inputs. The speaker enclosure’s design proportions are based on the Golden Ratio (1: 1.618). A low profile blends in well with room décor. Both vertical and horizontal installations are possible. Enclosure and grille net colour is off-white, except on the BS-1034S, which comes with a silver net grille.

The BS-678 is a double-cone type speaker with a wooden cabinet that has a stylish, compact and unobtrusive design and that delivers highly cost effective performance. A push-in type input connector allows easy cable connections and bridge wiring. The selectable input impedance can be easily adjusted by changing the tap position
of the unit’s transformer. 6" (16cm) double cone speaker unit ensures high-quality sound, making the BS-678 ideal for BGM and announcement applications. It can be installed in either a horizontal or a vertical orientation. Its structure permits direct wall installation with screws, making the speaker unit resistant to falling even if outward force is applied to it.
• Stylish, compact and unobtrusive design
• Quick and easy installation
• High cost-effectiveness
• Horizontal / vertical installation
• Ideally suited for BGM and announcements

The BS-633A/AT are wall-mount 5" (12cm) cone-type speakers with a compact and unobtrusive enclosure of ABS resin. Installation is quick and easy, and the speakers can be hook-mounted or mounted directly onto a wall. A push-type input terminal allows easy cable connections and bridge wiring. Input impedance can easily be adjusted by changing the tap position of the transformer. The BS-633AT comes with a built-in attenuator and can be connected to 2-wire and 3-wire systems. The speakers are highly cost-effective and well-suited for BGM and announcement applications.

• The speaker's smoothly curved surface permits it to blend in with virtually all modern buildings.
• A built-in matching transformer permits the speaker to be used for both high-impedance and low-impedance (8 Ω) applications. The impedance can be easily changed from outside the speaker.
• A splash-proof design enables the BS-1030 to even be installed outdoors, in a location not directly exposed to the elements, such as under eaves.
• Mountable to wall surfaces directly or using with supplied or optional mounting brackets.
