KEFReference SpeakersModel 101 Type SP1122Matching Serial Numbers #9322 A & #9322 B Welcome to August 10, 1981. Thats when KEF manufactured (in England) this matched pair of Reference Speakers, Model 101, Type SP1122. They appear the same now, as they did in 1981 (please review the pictures for the cosmetic condition of the speakers, and contact me if there any questions). These speakers have been incredibly well cared for. The components in these speakers (B110 & T27) are all original as built by the factory (see picture gallery). The Amazing Model 101 Reference Speakers can be summed up and characterized as having: Breathtaking stereophonic realism, superb tonal quality, plus a standard of technical accuracy never before achieved in a loudspeaker of such small size. I used two of the KEF recommended recordings for the listening test; Holst: The Planets EMI ASD 3649 & Wagner: Siegfried Idyll EMI ASD 3943 digital. They sound great. The KEF Reference 101 speakers with the B110 and T27 drivers are related to world-famous vintage BBC-designed LS3/5A currently selling ($2000+) broadcast monitors (search KEF 101s vs LS3/5A). Many enthusiasts feel the KEF 101 is in many ways superior to the LS3/5A. KEF Speaker History: Since 1973, THE REFERENCE has continually set the benchmark for loudspeakers.... Note: (View the Photo Gallery). These speakers have easy access to the control board. Remove the small pad on the bottom center of the speaker cabinet. This gives you access to a long screw. Remove the screw and carefully remove the bottom wood plate to expose the control board. (Careful: the control board is connected by a ribbon connector to the speaker cabinet). I did this to show the quality of the components and the complexity of the design. Some information about how KEF developed and tested these speakers Drive units for every pair of Model 101 loudspeakers are selected and matched by computerized digital testing equipment to ensure that each pair of systems will perform to the same high standards as the prototypes.The filter network used in the Model 101 is very complex and is manufactured to close tolerances in electrically matched pairFinal testing of Model 101 loudspeakers using the KEF digital impulse technique. Frequency response and other data are stored in digital form for every pair produced. Important FeatureThe Model 101 has been fitted with a novel electronic protection circuit — S-STOP (steady state and transient overload protection). You can see the S-STOP Module on the board photograph in the gallery.S-STOP: STEADY STATE AND TRANSIENT OVERLOAD PROTECTION S-STOP is a self-powered electronic circuit containing sensors which monitor the input to each drive unit and whenever the safe operating level of either of the drive units is reached, the relay operated attenuator reduces the input to the system to a safe level. A red warning light on the front of the cabinet comes on whenever the system is overloaded, and S-STOP is in operation. S-STOP continues to monitor the amplifier output during overload and automatically restores the full input signal to the loudspeaker when it is safe to do so. SpecificationsSee Photo Gallery for Original Detailed Specifications Notable Excerpts from Original Design Specs Model 101 has a reasonable bandwidth (±2dB from 90-30000Hz and still only -10dB at 47Hz).The Model 101 may be used with amplifiers up to 100 Watts to provide peak listening levels of up to 100dB spl.Every pair of Model 101s has frequency responses matched within 0.5dB.
