@tomic601 Brian - you speaker is quite unique w only a quarter million sold to music lovers and audiophiles- the acoustic coupler connects principally with the back wall. I setup and tune about 30 Vandy systems a year. Would love to assist with yours.
Thanks Jim. Primarily I use Richards instructions pretty closely, as best I can per the division of the room, tilt, etc. (Being an architectural designer, I’ve drawn-up my room in CAD with the various recommended division lines/points, etc.). But, I’ve done a lot of experimentation within and outside those boundaries, and a know what? Richards instructions seems to be fairly accurate for good sound. But what really made a nice difference was placing some absorption directly behind the 2CE’s (mine are about 2’-9” off the front wall) but also diffusion on the side walls behind the speakers as well, then more diffusion between the speakers covering my fireplace opening. That made a big difference as well.
