I pulled the trigger and bought them. I will pick them up tonight. As mentioned FS has an excellent return policy so i will basically have 30 days to try them out.

I read reviews and they are pretty solid for the RC-70's but the center channel and surround speakers that match with it aren't as well reviewed.

I know it's bad to mix/match different brands of speakers but I'm considering it. I know the SUB is usually the one speaker that is not always matching the others but what if my Center/Surrounds are from Axiom or Monitor Audio or another reputable brand? I know the only way to find out is to listen to them but I wouldnt mind some honest opinions on if i should even try that or just stick to the same brand for all 5 speakers.

The reason I didnt go for the M80 immediately is because of how picky it is with many receivers. I dont want to cancel out Onkyo or other brands based on the 4 ohms.
