Ananth,

If I understand what I think you are trying to say. The 3805 is a 7.1 channel receiver. For the rears and surrounds, which speakers are best for the surrounds and rears (Qs8s, M2, M3). Should they rears and/or surrounds be radiating or direct speakers.

I'm not trying to offend you, but I was confused and I think this is what you might have asked. If not, I apologize.
