Everyone's definition of bright is different. To me, bright means the high end is uncomfortable on the ears, not just an extended range. I'm finding my M22 Axiom system to currently be in the bright category, but am awaiting the delivery of a Pioneer AVR to see if I can tame what I hear with MCACC. Audyssey just puts them in the bright mode and leaves them there.
Good point, they definitely didn't sound uncomfortable to my ears at all, the high frequency sounds were just more noticeable at first. The reason I think I noticed is because my previous speakers just weren't doing a good job with the highs. I am using an Elite SC-67 which I love.
