Not sure if this is where to post. I just got a new onkyo 3007 and there are a ton of sound settings. I used to use ultra 2 select on my pioneer elite. The 3007 has Ultra plus but the THX website recommends this for a 3000 cu ft room. My room is a dedicated theater with traps, false wall treated floor to ceiling and the first two feet floor to ceiling as well as some diffusion in the rear. The theater is 22 long by 12 wide by 8 high. Any insight would be great.
