Just received another defective um18-22

DIY Speakers and Subs - www.avsforum.com
I just received my second um18-22 ultimate and this one is also defective. When I put it in my box and tried to test it, it made a weird noise. Removed the driver and tried to shake it and I heard a something rolling in the middle, like a debris or something in the middle of the driver moving all around. This is why the subwoofer was making a weird noise at extremely low level. Is there a way to fix it or should I just return it for a new one? My luck is terrible. The first defective one didn't even make it back to parts-express and now this. Really hope I don't have to send it back again.
