                 Technics  SB-K20 speakers, 1st pair - rosewood :
A wolf in sheep's clothing - this SB-K20 model was made and tested by me back in the early 80s at Fisher & Paykel. The light but powerful two-way ported bass-reflex K20 has nominal power handling of 60W but it took our 110W test amplifier turned up to 7.5 at about 70W - 90W to blow the red cutout button.

Simply reset the button and the speakers are ready to go - I never once blew up a K20 tweeter in the soak test, ever !

The sound quality is incredible, in terms of tone, musicality and good design - these K-20s are fantastic bargains. In common with the AR94s, simple design and good matching of components sometimes adds up to exceptional performance.

Specifications :
  -:®:-   Frequency response of 45Hz - 22kHz   -:®:-   Overload protection reset button
  -:®:-   A nominal impedance of 8ohms for 60W - 70W RMS power handling
  -:®:-   Bass reflex ported 2-way gives a measured efficiency of 91dB at 1Watt @ 1m
  -:®:-   Dimensions [H x W x D]: 650 x 350 x 253mm 
  -:®:-   Weight : ~ 10kg each packed
