Thanks for your reply dtel. I'll tried the large setting last night for the first time with a 4K sic-fi movie with lots of low end. I could hear the silverware rattling in my kitchen. Regarding your center selection, for a while I was using a Quartet on it's side. I had it in use for a few months before I decided it was just way too big (my HT is in my living room). I switched back to the Academy center and dont really notice the difference. In my next life I'll use it again in a room where the aesthetics dont matter. My wife would be happy if I got rid of the Forte's all together because of their size. I have them on stands that put the mid horn at ear level and it makes a difference. Unfortunately, it also makes them appear huge. Not sure I'll win that battle in the long run.
