Jerry, beautiful cinema. I cannot believe I had to coerce you into using HD in that room! laugh

re: boundary settings - I don't see what they can offer which cannot be achieved with MRC. Both can be used to change the output curve to remove room reinforcement in the bass regions. My speakers are right against the boundaries, but baffled on all sides by bass traps and foam to cut reflections and reinforcements, and then MRC'd to add that final adjustment which wasn't possible with physical treatment.
