Hey Everyone

I'm in the process of buying a house that feature a humongous bonus room. It sits over the two car garage.
I'm going for it! I'm going to put in an 11.1 system, and will be looking for an AVR that enables me to have height and wide speakers simultaneously.

I have a 5.0 set currently - the rt5000. I was going to put that downstairs in the living room, and was thinking to get a full set of matching KEF Q Series speakers for the Home theater.

Now I'm thinking...What if I just fill in around the rt5000 with additional Polks to achieve 11.1 in the HT?

Any thoughts? Recommendations on speakers to add to the Polks?

Just weighing options until I get into the house.

Thanks!
