When first configuring a system that includes 'large' L|R Main speakers, I run a complete setup three different ways: (1) with the L|R Main speakers set to SMALL, (2) with the L|R Main speakers set to LARGE, and (3) with the L|R Main speakers set to LARGE, plus "Extra Bass" ENABLED. Typically, one of the three configurations can be quickly eliminated, because the resulting bass response is either "too boomy" or "too thin" . . . then I pick whichever of the other two I think sounds better.
A good starting point for the AVR crossover setting is what the AVR's auto setup picked . . . based on the capabilities of the C|LS|RS|LR|RR speakers...
