A list of classic speakers that can be refurbished with our parts.

Based on the classic KEF driver lineup (B139 woofer, B110 midrange/mid-bass, and T27 tweeter), the following is a list of speakers that utilized these units, either individually or in combination. These drivers were extensively used in KEF’s own speaker models, BBC-licensed monitors, and various DIY kits throughout the 1970s and 1980s. 

Speakers Using B139 / B110 / T27 Combination
These systems typically used the B139 for bass, B110 for midrange, and T27 for treble, sometimes with additional super-tweeters.
