I would agree with the above post by pmbuko , this is definitely a room reflection/placement problem. Audyssey would set my QS4's at 60hz and I would raise it up to 80hz. I now use Dirac which does not control the crossover frequency , instead it measures the speaker full range and with my QS8's they extend down past 40hz though I still set my crossover to 80hz since I use 2 subs so no need to stress my surrounds. The room has a significant impact on how a speaker sound and reacts. Audyssey can also be guilt of exaggeration of the upper frequencies which is widely discussed in many forums. Share the layout of your room with a picture or diagram so others can help with placement and possible room treatment options.
