Technics SB-K20
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 - but I would say that - no really, I tested these in the anechoic chamber side by side with some of our best models including the SB-G700 cousin to the SB-X500A also in stock and the top of the line SB-10 honeycomb which of course won. 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.
