Really big improvement, openness, refinement, clarity, tonal specificity.
As I said the inside panels got covered in No-Rez.
Removed the binding posts and filled the holes with small rubber grommets and ran the wires through to the crossovers.
Placement is six feet out from the front wall, about 22 inches from the side walls, and sharp toe-in, so they cross a couple of feet in front of listening position. So, around 15 degrees off-axis.
