Nee your help folks.

I just setup a 5.1 system and hanged the surround speakers on the back wall since side wall placement is not wife acceptable.

Question is:

1. Should they be placed at least one or two foot away from wall like the front speakers?
2. Should they just be placed forward or could I toe in and tilt them slightly toward the listening position?

Also base on your experience, is EQ important or just distance/sound level would be enough for calibration?

Thanks for your response.
