So I just upgraded my mains to Cambridge SW T200 towers. I had the CSW MC300s across the front. Still using an MC300 for the center. Also have an older CSW PSW1 sub w/ S300s for rears. On the receiver, I had all speakers set to small. Bass out sub only. What's the general consensus when using full range towers? Should I set the fronts to large and bass out to both the sub and mains? I have an older Yamaha 5.1, so there's no auto audio setup, like I've seen on the newer Onkyo receivers. Not much of an audiophile , so I'm trying to find that right balance. I have thought about downgrading to a smaller powered sub, now that I have towers in place.
