"Snap of the E-145's.." - I think you nailed it. The E-145 is rather magical to me and "snap" is a great term to describe them. Although the 813's use lowly 2215's. I have kicked around the idea of swapping 2235's in, but was told to keep the 2215's and enjoy the 813's as they are.
Agreed. As much as I'd love to have 813's downstairs where the TV is, I don't have the space. So 811C's stacked on top of subwoofers it is.
