Bose sucks. Visit any audiophile forum; as I used to, and they trash on Bose almost as much as we trash on JU.
Bose is a poseur speaker. They have awesome marketing skills and a refined image, but their sound reproduction has alot to be desired. I'm not saying the factory Bose sound systems don't sound good, cause they do, but they are way overpriced for what they are.
Infinite, JBL, Polk, Alpine, etc. have so much more going for them. I know for a fact that most of Infinite and JBL speakers come from the same manufacturer; Vifa: a very high quality company that makes no compromises in accurate sound reproduction.
I don't believe that Bose sells their individual drivers independant of the enclosure anyway.
If you really need some good info, go to
www.partsexpress.com and speak to a customer service rep. They have god-like knowledge.
