The SVS sub is not available, and probably won't be until later on this year. The sealed 10" Carver will probably not be able to produce any deep bass, so I would look into getting a new sub. Check out the Outlaw Audio LFM-1 Plus, it will have great sound quality, plus it will probably punch a bit harder than the SVS PB10, and it is on sale right now for less. I think the sale only lasts until the 30th though. Another higher value sub would be the Hsu VTF2, also on sale, but not quite as competitively priced as the LFM-1 Plus.
