Largish Subwoofer for Soundbar (Waterloo L22)

Hi. Some of you may have seen my request for a faulty Orbitsound soundbar for parts for one I was working on. Well, I managed to fix the soundbar itself, but I still need a subwoofer speaker to complete the job. So if anyone has one that's taking up space and not being used I'd very much appreciate being considered for it. Many thanks.
