If they're all working, that would be a pretty good deal for $250-300.

The TSi300 is a big box. Compared to ANY bookshelf, you will probably perceive a fairly big difference, especially in bass. However, if you cross them over to a good sub at ~80Hz, I'm pretty confident that the Axiom M3 or M22 would be more accurate. As to whether or not you LIKE that accuracy, that's kind of another matter.
