The BS-678 Wall Speaker features a wooden cabinet and can be installed vertically or horizontally. It supports both concealed in-wall wiring and exposed wiring for speaker cable connections. The speaker's structure allows for direct wall-mounting with screws, ensuring it remains secure even if an outward force is applied. The input impedance can be easily adjusted by changing the transformer's tap position. Equipped with a built-in 6-inch double cone speaker unit, it delivers high-quality sound. The push-in type input connector simplifies cable connections and supports bridge wiring.
