Soldering in Speaker came loose - Possible scenarios??

[JJ]

Fellas,

I recently opened my box of new Wharfedale surrounds - one of the speakers had a rattle when I took it out of the box, and I feared the worst. Loose crossover part or something. However, when I popped the binding posts open to remove the rattle, what fell out was apparently a bit of tin soldering. My question is - what does this mean?

Something? Anything? Nothing? The speaker, a DFS surround, has dual tweeters and woofers in a bipole configuration. I would never be able to hear if a wire is loose inside a speaker until I tested them, and I haven't yet. What do you guys think it could mean? And if a crossover is disconnected/damaged, how would I be able to tell?

Thanks, guys.
