Hi, this speaker worked the last time it was used but I no longer have the rest of the system so I am unable to show you it working but I do stand behind my Craigslist sales and I am not here trying to take advantage of anyone. I am not interested in offers but you are welcome to bring whatever you want to test it before paying. I can probably come up with a power cord but I am assuming you are replacing a broken unit with this one and already have a power cord. Most Bose home theater speakers require special connection cables in order to set them up.
