Our price:
The BS-678BT, of 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 speakerstructure that permits direct wall-mounting with screws prevents the speaker from falling easily evenif an outward force is applied to. The input impedance can be easily changed by changing the tapposition 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-678BT have a built-in attenuator and can be connected to a 2-wire or 3-wire system.
