I wouldn't sleep on the CMX265's. It uses the Cal25 metal dome that was on the previous generation Profi Vanadium- its a great value on a set that likes to play loud and 'crisp' (thats why its in the PowerLine) like some fellas around here like to say. For the money, like every other Rainbow line- its very competetive and hard to be for quality, proven speakers. I say proven because the tweets were in a $700-900 set , and because of Rainbows constant R&D and new line releases- they can afford to give you that performance at a fraction of that in a new line.
