I just completed my system. Rti 38's for rears, Rti 70's for main, Csi40 for Center. PSW350 Sub. My question is for the speaker set up. I have to define if my speakers are small or large. Is the Csi 40 considered large or small, and what about the Rti 38's? Large or small? It seems obvious that the floor standing Rti70's are large. What should I set the LFE setting on for my sub I have it a 0 db at this point My receiver is a Denon AVR 3802. Oh and what differences is sound would I hear if I bi-wired my csi40 and RTi 70'? Any help would be appreciated.
