On room tuning.
You don't need to turn your room into an anechoic chamber. It's about first reflections. With time patience and an assistant it's easy to find those points. On each wall, ceiling, and floor there will be one point for each tweeter. Sit in your primo listening position, have some body run a mirror along the walls, ceiling (a little tricky but can be done with a rube goldberg'd mirror on a long handle at 90 degrees), and the floor. When you see each tweeter centered on the mirror from your listening position on the walls and ceiling those will be the point of first reflection in a typical room and where I would place some absorbent acoustic treatment. If the floor is bare wood those points could go with a throw rug. Depending on how close to the rear wall the speakers sit you may want something on the wall behind them. I went with something like this between the speakers on my rear wall, seemed to enhance the centerfill of the image.
Dipoles are a bit trickier because of the rear wave, but are usually out from the wall anyway so that rear wave will take a longer route around and treatment may or may not be wanted.
Bass traps helped me with issues that can develop at corners when wave cancellations and wave reinforcements (eigentones) making the sound thin or thick or lead to dead spots depending on where you sit in a room.
That's the way I set up various speakers I owned over the years when I had a home with a dedicated listening room. I found getting those first reflections under control makes for sharper imaging and better depth of the sound field. Especially in smaller rooms where the reflected 1st waves can cause a blur with the direct wave from the tweeters as the two signals arrive very close together time wise at your ears.
There is also a rule of thirds which says you divide the width of the room by 3 and that's typically the best place to position the speakers. Avoid placement numbers divisible by 2 if possible.
That's the sum total of my experience in room tuning.
