7p62mm, I don't believe there is an Avantgarde dealer within 200 miles of me in any direction, but I'll check. I would say that if you are seriously considering horn speakers, these are very likely some of the best (the Trios were a couple of the heavy weight reviewers "reference", at least until they heard the Pipedreams speakers). I don't care for horn speakers as much as some do on here, but I do like speakers that are dynamic. IMHO, dynamic range and dynamic contrast (with low distortion) are the main aspects that still separate the best loudspeakers from true "realistic reproduction". Try this test sometime: Take a spoon and a wine glass, and have someone stand between the speakers and clang the spoon against the glass HARD (just shy of breaking the glass). Record this with a DAT and quality microphone, and then play the recording back. Then you'll see what I mean. Even if you can't record it, do something similar with some other percussive instrument, and just try to imagine your system reproducing it. Seems like everyone feels that the recording medium would be the primary limiting factor, but I feel that it is secondary to the limiting factor of the speaker system (and the room set up philosophy, to a lesser degree). Speakers must transduce electrical to mechanical energy at a high energy level, so the losses are terribly difficult to overcome.
