Front wide right and front wide left is specific to the 6800? would this be for main speakers that can have a large distance between them i.e. 10'? I've never heard of that. I've only heard of the typical left and right channels..... Wides were offered on some older pre-Atmos avrs (like my Denon 4520), but not as widely (pun intended) used in later models. FWIW I tried and my room I just felt wasn't wide enough for both L/R and wides.
