I suggest you get a dvd calibration disc like Avia or Discwasher (which is cheap and easy to use) and recalibrate. That way the levels are matched from the player to the speakers/sub. Something is off somewhere or you need work on sub placement.

Also suggest you set the crossover at 60 with those speakers. Then experiment up or down 10hz at the crossover to see what sounds better and has less flucuation on the RS metre. Also flip the phase switch between 0 and 180 to see where its louder. And test the trim on the 600 from flat to half to see which setting has less needle flucuation on the RS metre. Finally a small movement in where the sub is located may make a big difference.
