Hey Chris, so you may have been around here a while?? I have not a digital camera or handy photos of the living room gear to scan, so you get a description...
My tower prototypes have two 8 inch drivers pretty far apart, flanking a dome tweeter. The distance apart was the critical factor in their mathematical modeling IIRC. Above the top woofer is a 5" or so cone mid and a 1" or so cone tweeter. The whole thing is 47 inches tall because that was the width of his Studebaker Lark back seat. About 12 inches square. I don't know how closely the commercial versions followed these dimensions or layout, I only saw it once at his factory in Placentia it might have been.
The more popular model was the TAD, which had two 5" mid/woofs flanking the tweeter. Now I don't know if he used a cone or dome for it. Several of the guys at school (Harvey Mudd College) had them. The grille was a wrap of open cell foam on three sides with end caps of finished wood top and bottom. Total size was at most two feet tall, maybe less.
I also have a pair of micro-TADs that follow the same design but with really small drivers and the whole thing is about a foot tall. They are at my folks house in the den. I used to have them in the back window of my car but that got to be a hassle (could not leave them there) so I kept them in the family. I wish I had gotten a pair of TADs long ago to complete the collection....

One cool thing about Vintage Audio is that we can now mostly afford to have the TOTL gear we could never afford at the time it came out. Love my recently acquired Yamaha and Luxman stuff. But I have had the Qysonics since about 1975 or '76 when I chose them over the Dahlquist DQ-10s I had planned on.
