I have had expeirence with the James products. They are a pretty unheard of brand name around these circles but they do make a nice speaker. In the showroom where I used to work we installed the grand concerto's for front L&R and had either the baby grands or the 83sdx i cant remember...for the rest of the speakers in a 9.4 setup. (with 4 EMB1200 subs)
The one product of theirs I really disliked was the powerpipe subwoofer. That thing is terribly boomy. That setup was really nice but its also very expensive. I think the Grand concerto's run 7k each. They did not sound 7K each good to me.
Axiom is also coming out with what appear to be nearly flush mounted in-wall speakers with a sealed back box compared to their onwall/inwall speakers. And from what I believe they will be eventually adding in even the M80 into that lineup.
