I have a barely used SVS SB12-NSD. It was purchased in July along with a PC12-NSD which was kept. I never got around to returning the SB12-NSD so it has been boxed and collecting dust since this summer. It’s an A-stock item and it was hooked up so I know it’s working with no issues. As much as I like this sub, I have no use for it myself. Price includes shipping and PayPal fees.
$529 shipped is as low as I'm willing to go folks so please do not PM with with ridiculous offers. SVS sells the B Stock of this sub for $599 shipped which typically include cosmetic defects. This is an A stock item that's barely used with more than 4 years left on the warranty.
