Took me about two years, main problem being bass cancellation from the front wall. Speakers have down firing subs, active and the distance from the front wall and side walls needed slight adjustments. The one note bass finally disappeared when traps on the rear wall and distances from the front and side were tweaked.
Also the tweeters needed taming, but I was relentless with tube rolling as the system is all tube components. It has all paid off and it’s been months since any changes were made. Honestly, the speakers were moved, sometimes fractions of an inch, at least a hundred times. Moved the listening position many times as well.
One thing I learned is that the sweet spot is the sweet spot. You can’t fool physics. Now, two people can sit on the couch and the effect off center is very tolerable, but no denying the sweet spot.
