Professional vs. Consumer speakers

I had another question I hope people here can shed some light on. Why don't more people buy professional studio monitors for home use? I have read some more reviews on pro speakers and most of those mfgr's say that audiophiles will not like their speakers. Because they are flat response, clear and accurate.
Isn't hi-fi supposed to be just those qualities? Also, ATC for example, uses soft dome tweeters which seem more like DynAudio's than metallic B&W etc. So I don't really see them as being harsh or bright.
Has anyone here tried or owned some of these "pro" speakers? Are we better off with the consumer models currently available?
