Solved! I want to connect a sub-woofer to my PC as a standalone.

I have a pair of amazing speakers i am using for my PC (JBL Control Xstream) but they are lacking in bass. If possible i want to connect a separate standalone sub-woofer to my PC to help this issue but have no idea how to go about this, preferably id like a high end brand name if possible.

Since the speakers are wireless you would have to get your PC to send audio to the speakers via BT and to the sub with the analog audio or subwoofer output of the PC at the same time.
I suspect that might not work.
If you could pair a BT subwoofer and the JBLs to the PC at the same time that would work but I suspect you won't be able to do that.
