Fellow NM here(Rio Rancho) and have Vandersteen Quatros in an ASC treated room. I started with the existing traps in place from the previous speakers that were in the same spots(Nola Viper 1AX). 1 half round behind and a bit to the outside of each speaker, 1 quarter round in rear corner, other rear corner is semi-open, and ASC panels center front wall, on the left wall, right wall and rear up by the ceilings. Speakers are 9" from the rear wall and slightly toed in to the listening seat producing a very pronounced holographic soundfield.
Dialing in the equalizers, bass levels and damping levels took no more than a day as the room response is pretty even and damped but not too much. I would start with a similar setup with your acoustic treatments and go from there. Feel free to PM me if you want, more than happy to help.
