Hacking a subwoofer that only connects to a soundbar

I recently got an sph4b-w wireless subwoofer from goodwill. my problem is that it can only connect to a soundbar that comes with the package. I wanted to see if anyone here knew how to trick the receiver into thinking that my laptop is the soundbar or if there is something I can do to the hardware in order to make it connect to any other device rather than only the soundbar transmitter.

YO dummyme, Were you ever able to figure this out?

Not within the same hardware. I had to get a separate subwoofer amp since the LG one is locked to a specific frequency which is lower than that of Bluetooth.
