Hi:
I agree that your weak point in your home theater is you subs as well as wall treatment. I have an all Wilson Audio home theater probably similar quality your system. I have 2 JL Audio E110 subs and to be honest I only need one. When I shut of the second sub and close my eyes I can't tell the difference. Will probably sell the second one if you interested. But buy one first. I made the mistake thinking I needed 2. My room is about the same size as yours and I can feel the sofa vibrate during deep base levels.
Good luck you have a great home theater.
