With my modest Denon AVR, I listen to music Videos/SACDs/CDs in my medium size room at about -20 DB. Over than & it just gets too loud - over 90 DBs at my MLP.

For movies I run it at -15 to -10 DBs because that is all that my hearing & my house can stand.

Something doesn't seem right with your gear, room or perhaps the source material. It is doubtful that it is the speakers alone that are the culprit.

Again, you should try to measure your SPL at your MPL to see exactly how much you are achieving. If you don't have a dedicated SPL Meter, there are apps for cell phones that will give you a good approximation of your SPLs. I've used both types & they work pretty well...
