Okay, I don't know if this is a "deal" or not, but I wanted to post it.
Right now, there's an
SVS 16-46PC on eBay, 1 day left on the auction, seller has 100% positive feedback, and the current winning bid is $180. It's roughly a 2003 model, so it doesn't have one of the latest drivers or amps. To get that sub for about $200 would be a great price, though, IMO.
Shipping would be quite a bit, but the seller is in Phoenix, so if you live near there and want a good sub - you might want to think about it.
