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.
