A pair of Kef 104 Ab s in really nice condition has arrived, one owner who has just bought a home theatre and will probably never use theme again.
The lineup includes the T27 tweeter as used in the LS3/5a, the SP1039 with it’s short coil and long gap for least distortion, and the passive radiator based on the B139, the SP1042.
Will sell for $300, collect only in Blackburn please.

KEF’s 8” bextrene unit, the B200, appeared in 1970 and along with the B139, B110, T15 and T27, comprised a range of drive units, under continual development, that formed the mainstay of KEF systems from 1967 through to the late 1970s. The B200 and T27 were combined in the two-way Chorale in 1970, which replaced the Celeste as the company’s best selling product; and the B110 and T27 were chosen for the famous BBC designed LS3/5A broadcast monitor."
