I now think I am having an issue with my crossover settings. When playing 7CH stereo with all speakers set to large I am still getting bass from my sub. I can change the amount of bass by changing the crossover setting on my mains. As I raise the point above my base setting of 60 I get more and more bass from the sub. I thought with speakers set large you would not get double bass unless you use the bypass settings. Plus, how can the crossover be affecting the bass when all speakers are on large.

Also, with all speakers on large when I change my mains to small, the bass from the sub does not change but my surrounds decrease their output by 6db without touching any setting pertaining to the rears (size, crossover). I don't understand how changing the mains from large to small can affect the output of the rear speakers.

Any help is appreciated,
Scott
