Does anyone have info on Innotech D-24 loudspeakers designed by Shahinian?

Hi all

i have just bought my second pair of Innotech D-24 loudspeakers.  Dick Shahinian design transmission line speakers with two Kef  B-110s, a 1-1/2” mylar dome midrange and a 1” dome tweeter. My last set I sold over ten years ago and I have been looking for another ever since.  Beautiful cabinets and great for low volume casual listening.  This second pair has different tweeters from my first pair and everything looks original.  They even have an original badge.  Does anyone have any original specifications or info on these?  I need to build grills and my first pair were missing these as well.  Period photos or brochures would be great to see.  
Have you contacted Vasken Shahinian at Shahinian Acoustics in NY? Great company to work with and Vasken is very responsive, in my experience.

I'd love to know more about the Innotechs.  My father got a little magazine, which may have been put out by the Musical Heritage Society, which reviewed the Innotechs very positively.  Since I was interested in transmission lines at the time, I was excited to hear them, but they disappeared from the market before I ever came across a pair.
