Speaker Width?

Too wide should be at least 6-8ft apart 
and 8ft. where you sit.
when your speakers are too far apart you are decoupling the speakers from each other-mid bass,when you don’t have midbass you don’t have rhythm.
speakers should be slightly toed in 
unless you are using your speakers as headphones.

Speakers are too wide apart, 6-8ft
from midrange/woofer and 4-6 ft. backwall
8 ft.listening position 
slightly toed in.
keep it simple 

I don't think anyone is reading any of the previous posts.

It’s hard to generalize because different speakers produce different radiation patterns, the same speakers generate different acoustic patterns in different rooms, the listener position is variable and rooms without quite so many acoustic anomalies have a better chance of finding ideal locations. Rooms with no acoustic treatment have almost no chance, forget about it. But for those in a hurry try 5 feet apart. That should get you pretty darn close. No toe-in.
