I have read all of the info on this site and you say to set all speakers to small and let the sub do the work. My manual for my LSI 25's say "set to Large" because they have their own sub. What to do? Audyssey sets them to Large (I have an Onkyo tx-806) when I run it. The LSi 25's have two hookups in the back. the top for the speakers and the bottom for the subwoofer in them. What to you think is best? By the way, I have a powerful sub in the Polk PSW650.
