Stevizzy,
I had the Sopra's "dialed in" to the room, then later, when I added a pair of sub woofers and was dealing with the "boominess" in the room, adding bass trap after bass trap, the soundstage that the Sopra's were really great with suddenly disappeared. No problem, just scooted them forward an inch or two and "boom" that great depth and soundstage returned.
