It is nice to see someone who has played around with this stuff as much as I have. In the end, despite all, I think going back several years ago when THX was more in vogue, I believe their concept still applies today that in listening to both music and movies in a multi-channel format, the optimum way of hearing the sound as intended was to have identical speakers in their appropriate position for ALL channels. Of course, in the vast majority of home theater set-ups, this is just not possible,hence, the development of horizontal center channels and to a less extent multi-driver surrounds like the QWS4s/QS8s which, in the end, are still compromises and more affected by room acoustics and positioning. The QS series and speakers of their type, of course, are designed to replicate the multi-speaker surround set-up in theaters that is just not possible in the vast majority of homes.
