Kwk, if you go to this page, you can find a list - by region - of Axiom speaker owners who are willing to let you hear their systems:
http://www.axiomaudio.com/boards/ubbthreads.php?ubb=showflat&Number=184230#Post184230

you can get in contact with someone on the list by sending a PM or email, or by getting in contact with Amie for help.
some of those people in the list may not be available anymore.

those who have answered you are right; the only times my tweeters are harsh is when the recording itself IS harsh.
Axiom speakers are very revealing of everything, and when a recording is first class, then you have a hell of an experience, with pinpoint placement and imaging and realistic stage, even sometimes in the third dimension: not only width and depth, but also up-down.
