Sure sounds like your center speaker, either is faulty or your setting it to large is the cause with the low frequency capability.
As was suggested, try resetting to small.
Better yet, since you didn't mention problems with the front left or right speakers, why not just unhook one and substitute it tot he center position and see what happens, before you change setting of the processor, unless they are so different that they have no problem with the lower frequencies.
