John Dunlavy may not be with us much longer.

As far as we know, he's not dead, Tony.

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.

John will surely be missed. Below is an article than ran in Stereophile back in August, 1996.

That's a great interview. I may start looking for a pair of Dunlavys.

I met John at his factory several years ago when I was considering new speakers. He took virtually an entire afternoon to give me a tour, demo his speakers, etc.--a very gracious,intelligent and fascinating man.

He pointed out that all his speakers sound the same except for differences in bass response. I ended up buying the Cantatas and still have no interest in changing. I've heard many others, but the Dunlavys just seem to get things right to my ears in a way that I have not heard bettered.

I am greatly saddened by his passing
