I like it moderately loud(to many SPL contests in my life haha)Normal listinig levels, I would not go more than 3/4 way up on the reciever with my klipsch 8.5, that brings me to another question. Can i use the Klipsch 8.5 as a rear and my qs8 as R surround for a 7.1 or will that horn tweet totally distort the SQ of the axioms?
