The BS-678 is a double-cone type speaker with a wooden cabinet that has a stylish, compact and unobtrusive design that delivers highly cost-effective performance. A push-in type input connector allows easy cable connections and bridge wiring. The selectable input impedance can be easily adjusted by changing the tap position of the unit's transformer. The 6" (16cm) double cone speaker unit ensures high-quality sound, making the BS-678 ideal for BGM (background music) and announcement applications.

The BG-678 can be installed in either a horizontal or a vertical orientation. Its structure permits direct wall stud installation with the supplied tapping screws 5/32" x 1-3/8" (4mm x 35mm). The BS-678 ships boxed as a pair of speakers.
