I have a Yamaha RXV 995 and I recently read a post that indicated that it was best to set the center and main speakers on the "small" setting and the subwoofer setting on "both". I have some decent size Klipsch speakers that do a good job of passing a decent LFE signal. I also have a Klipsch subwoofer. Does it make sense to set the Mains to "small" and not "large". Apparently if you set the Main's to "small" and the sub to "both" the LFE signal still gets passed through the mains in addition to the Subwoofer. Any thoughts on this? Thanks.
