ES channels...how close/how far ?

[kgveteran]

My upgrades to new surround speakers (RS28a/RS225) courtesy HT Guide, leave me wondering how far apart to put the ES (back) surrounds.

The sides will be (of course) to the sides of my couch, the tweeters will be 57" above the floor.All (surround) speakers will be wall mounted.

The back wall is 14' wide.The sofa is 5' from the back wall.Murphies law put a door on that 14' wall also.

So, close together or farther apart. I may just leave them unmounted and run some demo's also, just to see.

This will be my first experience with 7.1, wondering how different from 6.1 ?

Thanx guys

kg, I also have a 14' wide room. I read more than one recommendation or calculation while I was designing my theater that the rear 2 speakers be put close together. I spread them just a bit, and now I think they're about 4.5 feet apart, if I remember right. Works great--I wanted more separation between those two channels when they're playing discrete information.
