SPEAKER DIRECTORY

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
