I have had 6 pair of speakers In this room. The problem had nothing to do with speakers but was created by a room designer who didn't pay attention to the details and then refused to own the problem. With help from people I have communicated with on various internet forums and GIK Acoustics, the problem is 85% resolved and I'm still working on the other 15%.
As for the Maggie recommendation, the 20.1's were one of my two primary possibilities when i was doing my speaker search but the local dealer apparently had them set up poorly because there was NONE of the Maggie magic so I went elsewhere
