Phil Jones' AAD 2003; any information?

Hi. I am a recent purchaser of a MINTY :) pair of AAD 2003 tower loudspeakers. I heard them at a friend's house & just had to have them. I traded my trusty pair of Von Schweikert VR4 (only a tad bit of trader's regret) plus a little cash. Overall I love these speakers. Part of the allure is the sonic "trick" they perform; impressive bass response from just two 5-1/4" mid/bass drivers. I actually get slightly more bass from them than I did from my VR4s in my particular listening room. Anyone have any info on these speakers? I have learned from snippets online that they were designed by bassist/speaker genius Phil Jones and that they retailed for around $4,800.00. I know AAD was located in Raleigh, NC, and I think it may have been related to Soliloquy (also now defunct). They are impressively constructed, and weigh in at a hefty 140 lbs each, despite being only a mid-size 2-1/2 way floorstander. I don't know anything about the maker of the drive units, although visually they appear to be of very high quality. Also no info on whether these use a transmission-line design or just how they produce such impressive bass. They are ported in the rear via two smallish ports located on the brass connection plate. Any info on these speakers would be greatly appreciated!
