The B2 was designed to be a sort of stand-alone Bluetooth speaker and is able to receive Bluetooth data and also has a mini-stereo input; because of this, it doesn't have any outputs to connect to the S8. Since the B2 does have an analog input, if the subwoofer has both inputs and outputs you could connect your source to the Subwoofer's input, and then use a cable to connect it's output to the mini-stereo input of the B2. It's important to note that doing so would only work for the wired input going to the subwoofer, and not for Bluetooth audio streamed directly to the B2.
Can I use a subwoofer with the B2?
