So you moved the better speakers to the front of the cabinet to avoid reflections?
The new speakers' fronts are slightly in front of the cabinet, and at the outer edge of the wall. They are 10.5" off the back wall, KEF says something like 9" minimum, and recommended I stuff the port with their provided paper muffle (which I did). The new sub is about the same width as the old so should fit i the same spot, but unlike the old which is downfacing will face outward, so won't be in a cave of sorts from the furniture.
The center is right at the front edge of the glass top.
I may try putting the sub outside the towers, which would look better, but the seating in the area is at or somewhat outside where they towers are now, so that would make the sound at the outside seats worse, I think, if they are put in closer. As it is, they are a bit of a road hazard of someone going around those corners.
In this shot the console is probably 4" further forward than I hope to get it, I've got some balled up sub cable (it's like 30' and really heavy) that I need to fix by buying a new coax cable, which this is a good reminder of, thanks.
Advice welcomed.
