Here is a picture from a show at the Rams Head in Annapolis, MD
My ADK's are spaced approx 26 inches apart and wrap around the column... serves as a psuedo Jeklin Disk. Tape came out great. The schoeps in the middle served as a baseline for comparison.
If you have something in the middle the spacing is fine. Also, remember the middle peg could be used to mount a Jeklin Disk/Baffle on it.
