Hi folks, I currently am running dual SVS 20-39CS subs with Samson S700. I have a friend who wants to buy them from me. If I sell them I will have to fork out another $500 Canadian to upgrade to the dual 20-39CS+ series with Samson S1000. The day after my subs shipped SVS announced the CS+ series and I didn't want to go through the trouble to send back my cs subs when they arrived but I would have ordered the + series had I known. What would you folks do ?
