Query: No good for sub-woofer

I purchased this to connect a sub-woofer wirelessly to a A/V receiver. There was an article on the Buttkicker site indicating this would work. However, it did not work at all. I contacted Buttkicker directly & talked with their technicians and they indicated it should not be used for that purpose. Therefore, I returned the item.
