since i don't own any yet, i can't give you that "real world experience" (which i would think would be a little different for everyone) but the manual says

"Placement / Positionnement
Quadpolar surround speakers in a 5.1 system will sound their best and produce the greatest sense of envelopment in the surround soundfield if they are to each side of the listening area (see diagram) rather than on the rear walls, and from 1 to 5 feet above the level of seated listener’s ears."

I do plan on getting a pair of these great surrounds for side surrounds and i plan on putting mine 3' to the bottom of the spaker from my ear level. hope tht maybe something here helped. of course i wouldn't mind hearing from other on this either.

good luck with the "real world"
