DIY Speaker Project PAD

What criteria should be used on the near wall far wall decision on cross over?
In Jim's write up he states :
All of the Statements series designs are to be listened to off axis and positioned pointing straight ahead with 1 ½" of distance from the back of the speaker to the wall behind them. They will work surprisingly well closer but further out is better. The Monitors have gone a step further. Curt waved his magic wand and created not only a far wall version that is designed to be used out into the room but also a near wall version that can be used as close as 12" from the wall to the back of the cabinet.

The 1 1/2" distance is for Statements and the as close as 12" for Monitors, at what distance should I be looking to change to far wall?

That should have read 1 1/2' or 18" is the design distance for the far wall version. It can be used down to 12" but closer than that and I'd recommend the close wall version. I would not use the close wall version closer than 6" - 8" from the wall behind.

These distances are the design distances to allow proper blending of the bass to the mid/tweeter.

If you want to use the close wall version more than 12" out, I'd suggest using the far wall version.
