Well my thing is balancing space, my “theater” room is 10 by 16. My TV is centered at the 10’ portion which maybe obvious.
my TV is 65 inches, my tv stand is 60” so now I got 2.5 feet on each side. The sub decoupler is 24x32”
so I’m losing space quickly.
Your set up looks grand, but I think I can recess the speaker stands under the TV stand. I get safety included for a good price. Plus my ear level is 36”.
Im sure your that stool is equally high. But what I can do now is my tv stand can stabilize the speaker stands. It has 2 inches to interlock under to keep the base pinned to the ground securing the speaker stands.
Those stands can’t tip or fall and the base is a solid size too.
