Recently I contacted SVS customer service by phone to inquire about the "Trade-Up" policy advertised on their website as item #6 in their so-called "Bill of Rights": PROMISE #6... 1-YEAR TRADE-UP POLICY You may trade in any product purchased from SVS within 1 year of your purchase, and receive full credit toward the purchase of a more expensive like product. We ask that the product be in like new condition with original box and packing. We ask our customers to pay any freight charges associated with the return and new purchase. Well, as it turns out the policy is only valid for purchases made since they started advertising this program, which I believe the representative said was on or about November 29, 2011. I had originally intended to inquire about trading in my two SB12-NSDs towards one of the new SB13-PLUS models, but although mine were purchased within the last year, they did not qualify because both were purchased prior to the commencement of this program. So, for those of you who have considered trading in your recently purchased SVS subwoofer, please keep the above in mind. This is not intended as a jab at SVS, because I do feel they make great products, but I definitely DO feel as though the above should be posted (at a minimum) as fine print below their "Bill of Rights."
