Diffuse sound is also why newer/higher end(?) avr's have 2 side surround channels to help spread out the sound when used with direct radiators in slightly larger than average rooms where you can actually get 2 or more sets of side surround speakers installed. With the QS series you can get by with just the one set of side surrounds till the room gets quite large and you have multiple seating arrangments, but even then one pair of QS's seem to work quite well on their own unlike direct radiating speakers.
