If your considering new surrounds, I would also highly recommend the Qs4's or Qs8's. I've yet not heard a better surround speaker. BOSE was good in their day, I also had some 901's in my college days, but I don't feel the current BOSE cubes are in the same league as Axiom's quadpolar design. In fact, I don't think any bookshelf or di-pole bi-pole brand of speakers can match the quality. Below is some results from my Axiom speaker polls on my website for the surround category. The polls have been running for 3-4 weeks, so I'm sure not all the Axiom owners have voted yet, but you can see the pattern...
QS2 (disc.) 1% (1 votes)
QS4 16% (27 votes)
QS8 82% (139 votes)
Non-Axiom Surround used with other Axioms 2% (3 votes)
Good Luck on your decision.
