You need to angle them, also, position them using the equilateral triangle setup. Angle is super important. Try aim it and you, aim it before you, aim it after you.
Audyssey will help a lot, REW too. These are not the easiest speaker to position.
Also, turn off any "enhancer" function in your receiver.
Plus, I think you are sitting too close to these speakers. Your room may not be big enough for them.
