Heath, if budget is a factor, here is another sub you might consider. It is very new, so there isn't much feedback on it yet, but av123 makes good products, and the customer service is on a par with Axiom's. Both are excellent. It's only an 8" sub so it won't reach quite as deep as the the JBL, and BIC, but it comes close.

It's available in white shadow maple as well as in black.
