What you are looking at getting is actually what I have, but the OWM3's and 5.1. The whole system bumps and sounds very good. My room is about 20X15 with vaulted ceilings and it makes me not want to leave my living room, ever. I see a lot of people hate on Polks for some reason, but it can't be their sound quality. I haven't heard every speaker, but from what I have heard, Polk makes a great speaker. I bought my whole speaker set up for about $1400. And the Polk sub I have is very powerful for being so small. It hits very tight and accurate.
Although we all don't agree on speaker brand, I think we all agree that you should NOT buy Bose, ever ever ever!!!
Good luck with whatever you choose!
