You will likely get a lot of responses to your questions, but for the question of “which ones” I would advise you to call Axiom. They will recommend the best option to you (not try to up sell you). Several people have commented they were told to get the next speaker down (in price not quality) as they would better fit their needs.
Concerning the QS8 speakers. I have them right behind my listening area about 3 feet above ear level. They are, in a word Fantastic. They are most likely the most forgiving surrounds you can find.
There are several folks who have ordered from the factory seconds and been very very happy with their speakers. Most have found no flaws in their 2nds.
