TOA BS-678B Wall Mount Speaker

The TOA BS-678B Wall Mount Speaker which cabinet is made of wood 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 TOA BS-678B square box speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force is applied.

In this TOA box speaker, 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.

Note: We have individual mosques sound system packages and classroom sound system packages.
