I found this on eBay tonight. If you're on a slim budget and you need a small sub (or two), these little 8 inch guys are pretty good. In fact, for the price, they're amazing. Shipping is $19.95 for one...an additional $8.95 for a second one, if you desire. Two subs delivered for under a hundred bucks.
One day is left, and 14 are remaining, as of 3:15 a.m. Pacific time, Friday morning.
(The usual disclaimer here....I have no connection with the seller or equipment manufacturer. You're on your own with any purchase of these.)
