Hey Blobula, where in Iowa do you live? I think we have 5-6 people now in this great state?
The Qs8's are specifically designed for surround purposes. Because they have 2 woofers firing up/down, and 2 tweeters firing left/right, all at the same time, you are totally enveloped in the experience. Direct radiating speakers (bookshelfs) can't provide the same experience. Now some people will use bookshelfs for the rear speakers in a 7.1 setup, however, for the left/right surrounds, you really want Qs4's or Qs8's.
Talk to you later.
