I really appreciate all the options GIK offers...I've been a customer for over ten years, but with Magnepans, you don't really need a lot of treatment. I'm also running ARC room correction, so things were sounding pretty good. But the rear/seating wall was right up against the couch, and I wanted to toss up something to help, while also being somewhat stylish since it's the main room of my house. I think I've accomplished what I was after with these. Center channel dialogue in particular is improved and more intelligible. Wasn't bad before, but now it's crystal clear. Love this company.
