Pair of KEF 104aB Reference Monitors

True 1970’s British Classics

These glorious monitors are in full & perfect working order, all original and excellent physical condition (see close-up pictures). The foam grilles have long since turned to dust but we have purchased new replacement acoustic foam grilles from Wilmslow Audio - shown in picture 2.

If anyone tells you that there is no difference between the original 104 and the 104ab up-grade then they are most definitely wrong. The 104aB up-grade uses an improved Butterworth type crossover, which not only decreases the colouration evident on the earlier 104 models (making a great improvement to voices and stringed instruments), but also increases the power handling from 50 to 100 watts RMS. Pictures 13, 14 & 15 tell the upgrade story and associated benefits.

These will be supplied to their new owner with their original sales brochure, along with the pair of original logo badges shown in picture 16.

The last picture is from the 1979 Hi-Fi Year Book.
