 zd TOA WALL MOUNT SPEAKER BS-678
BDESCRIPTION
The BS—6/8, of which cabinet is made of wood, can be installed in a vertical or horizontal orientation.
Fither concealed in—wal 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. Iwo built-in 6—inch double cone speaker units deliver high quality sound.
he push—in type input connector makes cable connections easy and allows bridge wiring.
