Charles and Fred, I don't mean to say that there's not more to achieve--otherwise they wouldn't be making improvements all the time! But I don't think improvements could be made in the way that 2x6 is suggesting--if they could be, I think Axiom would have. What I'm (and I suspect Peter is) objecting to is the idea that Axiom would be better served by pricing their speakers higher and using esoteric components. Like Peter said, I'm sure they've tried them and found no difference, or none worth speaking of.

I am the Doctor, and THIS... is my SPOON!
