A:Answer No. Unfortunately, Vizio designed their soundbar systems to not allow "pairing" with more than one subwoofer. Worse yet, they usually will not pair with a subwoofer that didn't come with the soundbar from the factory. I have two SB3651-F6's and either one will not pair with the other's subwoofer. So, If you have a good bar and the sub stops working, you can't just simply buy another SB3651-F6 sub and expect it to mate with your bar. That's just a huge wrong, imo.
