#1 - Search this topic in the forum. There are dozens of lengthy threads about it already.
# 2 There is truth to what Sharka says.
#3, The CLR's are popular here, and it's for a good reason. They are not the only solution, but they are a good solution.
I have 2 CLR wedges. I have used them as monitors, as PA tops, and as a backline for about the last year. They are pretty darned good. I've personally never really heard a more clear and articulate monitor. There is not much low end in them, and they will not give you a real (4x12) amp in the room. They are loud and can compete though. There is no thump, no real air moving at you if you care about that sort of thing. The reproduction of the tone is accurate, but they do not sound the same as my tone coming out of our PA mains (QSC KW 153's) Mainly, the tone in the 153's is fatter, fuller, and awesome.
But, for monitors in front of me, they do a great job of letting me hear what I need. I often use IEM's now, but I still always have my CLR's there so I can feel something, and so I can get feedback etc.
