I had a pair of 1090s, I do miss not having the dome mid in my 570s. The 570s are not as smooth as the 1090s and do not image as well as the 1090s or 1290s, but they punch a little better in the low mid. I bet those sound good being a little 3 way. I would not gut them, they look really nice and bet sound great! If you moved them away from the back wall into the room a little more for critical listening it would probably smooth that hump in the low end and sound nicer away from the glass.
