This can be a maddening process. I researched many online demos and used various calculators showing where to place the speakers based on room dimensions. Most would put my speakers way too far into the room in both distance from back and side walls. Cardas method 1/3 or 1/5 Golden Ratio....etc.
So, I am still moving and trying. What I am having the most trouble is with the center image. Sometimes it seems to shift a little to the right. Do I move the speaker out/back, sideways...uggh! I have also noticed that not all recordings are centered.
I suppose mono recordings is the best to use.
BTW, even though the Townshends podiums under the speakers makes moving them around very difficult, I would not want to be without them. They are that important.
