Question Vizio 5.1 compatability

[insaniolanio]

I have a set of SB3851-c0 subwoofer with satellite speakers. I was wondering if I had another option of soundbars besides having to buy a whole new sb3851 bar, which is impossible to find a working one online.
I've already tried vizio chat support and they have no official way of knowing if others would pair with the wireless subs. Through research of my own ive vaguely concluded that I would at least need another 5.1 Vizio soundbar. Any new information would help.

Since those things pair wirelessly they would need to be matched unless the sub has a "link" button or something then it may work. I've seen this question before but don't remember anyone ever doing it.

Hey hang-the-9, thanks for replying. So Iv'e done some digging into the FCC ID's of the wireless module on the sb3851 wireless module and discovered that the sb3251 and the s3851x-c4 use the same wLL701 5g module. I have more confidence that I need one of those models to even have the slightest chance of pairing the wireless sub to the soundbar. Also, the sub does have a "pair" button and in the quick guide states you hold that button and the power button on the sounbar to repair the two.
