Thanks for all the info guys, I am sure I will get used to the full sound of the components over the full range Polks I had. I was hoping on maybe some breaking in time to balance out or something, I think I'll take the advice and back off the gain some cause that is where it seems to sound the best. I guess I expected a lot more outta the MM6501's they don't keep up with the two 12" I have at all.
