Am i sitting too close to the Center Channel? (around 3 feet)

Center’s placed too low. Center should be identical to fronts.

Disable center channel and just use the 2 Fronts and Surrounds. The phantom center provided by the fronts should be fine for a single listening position such as yours.

Thank you for these suggestions. Especially trying the manual setup. I just assumed i could never do better than professional software. Worth a try..

I would start here instead of using that Ekhorn signature base ottoman. Definitely can’t be doing you any favors.
You have plenty of room for subwoofers. They make some pretty good micro subs these days look at REL acoustics https://rel.net/?gad_source=1&gclid=CjwKCAiA8Lu9BhA8EiwAag16b-0UmMU6_C4w4cqO9pxfo4jHIj3lF5-gPpbeJ6Ce36PPqek1pV2pZxoCjbQQAvD_BwE

also try setting up the speakers manually instead of using the room correction feature.
