About the Reference 101

The KEF Reference 101 is a compact, high-performance bookshelf loudspeaker originally produced from 1979 to 1986. It combines the T27 tweeter with the SP1057 version of the B110 bass/midrange driver in a 6.7 litre closed box enclosure. The system includes KEF's S-Stop electronic overload protection to safeguard the drivers from damage and features mechanical decoupling of the bass driver to minimize coloration. Each pair is acoustically matched within 0.5dB for consistent stereo imaging and tonal balance. The speaker is designed to deliver accurate tonal balance, detailed stereo imaging, and smooth frequency response, making it suitable for use with high-quality electronics and unobtrusive in listening rooms. It was designed as a high-quality alternative to the BBC LS3/5A monitor and is noted for its flat frequency response down to 90Hz (-10dB at 47Hz). The Reference 101 is housed in a strong cabinet veneered in walnut, teak, rosewood, or black ash, with a black cloth grille. It is recommended to be used with amplifiers rated between 20 and 100 watts per channel into 8 ohms.
