This is something I really don't agree with, or better yet don't understand. Does Audyssey, YPAO and or Pio configuration programs all say regardless of what it comes up with set speakers to small and a specific crossover - IE basically ignore what the program is/are sensing/reading? One would come to the conclusion that with all the advancements and refinements within these configuration programs if you were meant to set speakers to small regardless, it would recognize the sub and just default to all speakers being set to small... This is honestly a question I have had..?
"Headroom" is one thing but most don't listen that loud to worry about it. The reason I bring this up is I just recently added two DIY Rythmik 1510 kits to my HT. Basically two beefed up F15HPs. My mains and surrounds are all identical large powered towers that YPAO sets to large and 40Hz. Prior to having the subs I ran all four of the large drivers as independent subs via RCA and set the towers as Small and 60Hz. Basically would perform a 5 or so position YPAO run and then tweak the "size" and crossovers etc. With the towers now speaker wire only and the sub-out RCA runs going to the Rythmiks, I let YPAO do its thing as well as experimented and played around with my own ideas - meter and all.... The best overall soundstage came from the 100% YPAO config - of which had the four towers set to "large" and 40Hz. I would not have thought this would be the case yet came to the same conclussion as JT78681 above - I'm just going to leave it as configured by YPAO and listen for a bit...
