As most of us keep posting, YOUR ROOM is the most important variable in any sound system. Otherwise, why would builders hire expensive experts when they build a concert hall? Just go with the lowest bid and get on with it, right?
I have installed the best speakers (Maggies) in some rooms that will NEVER work for them for a number of reasons that most of you probably have run into over the years--size, shape, placement, furniture, etc. When that happens, either fix the room, IF YOU CAN, move the speakers (DUH!), or buy other speakers.
Like drag racing, once you plug in the numbers, that's the best you are going to do since you can't "beat" physics. Same with audio. Once you have done everything possible to fix the issues, you have to move on. Physics is physics, sorry to say, even in today's "science ain't never done nuttin' for me" world.
Cheers!
