Toa bs-678 Wall Mount Speaker 70V 100V 3W Wood

Product Description

The TOA bs-678 is a wall-mount loudspeaker designed for background music and public-address distribution systems in commercial and institutional settings. The enclosure is constructed from wood and supports both vertical and horizontal mounting orientations. Wiring can be run concealed inside the wall or exposed, depending on the installation requirement. The unit houses two built-in 6-inch double-cone speaker drivers and incorporates a tap-adjustable transformer that allows operation on 70-volt or 100-volt distributed audio systems with selectable power levels. A push-in input connector speeds up cable termination and supports bridge wiring configurations. Licensed audio or low-voltage technicians typically handle installation in these environments.

The bs-678 is suited for indoor applications where a compact, unobtrusive wall-mount speaker is needed in a distributed audio system. Typical deployment environments include retail spaces, classrooms, corridors, offices, and institutional facilities. The combination of wood enclosure aesthetics and transformer flexibility makes it appropriate wherever a 70-volt or 100-volt system is already in place. The mounting structure is designed to maintain a secure connection to the wall surface even when outward force is applied, reducing the risk of the cabinet pulling free under load.

Key Features

• Wood enclosure cabinet for aesthetically neutral wall integration
• Two built-in 6-inch double-cone speaker units for full-range sound reproduction

Compatibility

Designed as an OEM-style replacement or new-install wall-mount speaker for 70-volt and 100-volt distributed audio systems in commercial, educational, retail, and institutional environments.

Installation Notes

Installation is typically performed by a licensed low-voltage or audio systems technician. De-energize the amplifier and distribution system before making any wiring connections. Select the appropriate transformer tap for the desired power draw before finalizing the installation to ensure the total system load stays within amplifier ratings. Verify local electrical and building codes for requirements governing speaker placement, wiring methods, and plenum-rated cable where applicable.
