Ok I have them setup juggling time with work and parents and preparing to move so this has been difficult to get time in. I'm looking forward to this weekend

The one thing that stands out the most is the size difference the Klipsch are beasts The JBL's are just monsters

I have them setup starting at 5 feet 4 inches. From tweeter to center tweeter on both sides. Will work with adjustments and different toe ins from there.
Going to make sure there level matched and manual eq in I never use room corrections. Just my preference I turn all that off on any system I use.
Run them on low to break in my ears for a couple days I've never been a fan off speaker break in but I do believe in ear break in lol
