I have a setup with the R10's as my fronts in a small room with the CS1 as the center with a Yamaha rx-v659. Would it be worth it to be step up to the Monitor 30's for the sole purpose of voice/timbre matching? As far as i can tell the R10s and the Monitor 30's have similar specs with only the tweeter being 1/4 of an inch bigger in the 30's. The lower and upper -3dB limit is also slightly different. Thanks.
