TOA BS-678T Wall-Mount Speakers

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
