Polk RM30's

[JunkBoy]

I'm looking to go in another direction for my front speakers but I'm somewhat limited because our HT is built around an already existing bookcase. I'm currently using Bose 901's as my front speakers and the bookcase was built to hold those speakers. I've been searching around looking for similar size bookshelf speakers but there just aren't any out there so I've decided to look at possibly mounting some speakers beside the tv since towers are out of the question for me. I have some space on both sides of my tv where I can mount speakers to the bookcase and in doing my research I came upon these Polk RM30 speakers:

Size wise they can work and mounting them will be no problem. I'm just wondering how good these speakers are? I've found 1 review of them out there but it's on the link provided from Polk's website. I got a chance to hear them over at Frye's and they did sound really nice but I guess I'm looking to get some other opinions on these speakers.

I currently have a mish-mash setup of different speakers for my 7.1 setup:
Infinity center & sub
Bose 901's up front
Bose 301's for the surrounds
and Pro AC speakers for the back surrounds

The center and surrounds are perfectly fine for me but I would like to replace the fronts and just maybe the subwoofer (depending on how good the new fronts sound). Any opinions on these RM30's or other suggestions would be greatly appreciated.
