For sale. SVS 20-39CS+ sub, serial number 52. I purchased the dual 20-39cs+ package with the Samson 1000 amp from SVS. The subs arrived in February and I’m very happy with the set up. However, two subs are just too much for my 12x11 room (in both size and output). One 20-39cs+ is more than enough. So, I’d like to sell the second sub for $525 that's below B-stock prices. Buyer pays shipping from zip code 87111. The sub is in MINT condition and will be shipped in the original box with owners manual and port plug. The cs+ is an amazing sub and the guys at SVS can't be beaten when it comes to producing a great product and providing unsurpassed customer support. Don’t miss this chance to buy a GREAT sub at below B-stock prices. Please email me with any questions.
