John passed away a few weeks ago. Today I have contacted Kiat Low (Duntech Australia owner, see above) again and now and I'm very sad and sorry that I have to tell you that John Dunlavy passed away in January 2007. John was without any doubt one of the greatest people in the audio industry! We will never forget him.
The good news is that Duntech continues the development of loudspeakers based on John's remarkable designs and Kiat is currently working on an update of the SC-IV/A, called "Princess". Duntech's new smaller model is already better than the Wilson W/P 8 by the way.
