The QS8s are preffered because in our smallish rooms, compared to real movie theaters, it is hard to get direct radiating speakers to spread the sound out and surround you. The QS series have no drivers aimed at the listening position so the sound is more diffuse/spread out and envelops you, it doesn't hit you like direct radiating speakers do. Some people do not like the diffuse sound of the QS series but most appear to feel the design works, it sounds more like the big surround arrays they have in theaters all the while only using 2 speakers.
