Loudspeaker BC1

Standmount hi-fi stereo 3 way bass reflex loudpeakers housed in wood veneered cabinets with stands. Factory finishes included teak, walnut, rosewood and black oak.

The original BC1 design lacked the Coles 4001G tweeter but few were built. A limited edition version of this version was re-released in 1994 as the Spendor BC1/69.
