I had RF7's and Definitive's back years ago... The 7's are a horribly placement accute, and equipment finicky speaker, and will never ever sound balanced especially with rock music, the mids and Highs are far to hot to ever get the output of those dual 10's that under perform in the firstplace to get enough air moving without cranking and getting a headache from the etched sound they will produce, they are however a great Theater speaker and Movie dialog would never be a problem with them, but not by any means a musical speaker in the end... Definitives will never have the output and dynamic capabilities you will seek in the end, they will sound kinda veiled and boring. I agree pretty strong with Bigjoe and he has you on the right track... By the way I listen to very heavy and midrange strong rock in general, so you need much more finess and control then you would for excellent hi quality Jazz or blues type music, thats just a fact... So the fact is that something like those mcintosh speakers or polks do have more of a design factor, being multidriver and natural material built drivers that you seek.
