I have a pair of RC Mini's and they're very similar to your V-mini's.
17 x 16 is a good sized room but the Mini's might be okay. Did you get a great deal on them or something? The reason I ask is because the V5.1 is only $30 more right now at Vanns and would be a much better choice.
I have RC Mini and RC-10's and the difference is pretty significant, more bass and room filling sound from the larger speakers. It would be the same between the V Mini and V5.1. I would at least want the larger V5.1 as my front speakers instead of the V Mini.
As far as subwoofers, the guys in the subforum would probably recommend one the following speakers.
I love the V-minis, and ironically also have mine hooked up to a a Denon 2112ci in a slightly smaller room. I suspect Pipa is as happy with his, as I am with mine. IMO they are superior to the RC-mini.
