Insulation under speaker?

After test driving my speaker for a few days, I noticed some insulation (about a cupful) under the speaker ports. Anyone else experience this? Is this normal?
I don't seem to have any sound quality problems from it - it still sounds awesome! (My next door neighbors called tonight to ask us to turn Empire Strikes Back down at 9 PM - its in a basement and our houses are separated by almost 50 feet!)
Thanks!

Check out this thread - there's been at least one other case of some of the packing fill escaping due to shipping. If you get any more, you might want to check in with Outlaw, and if it is enough to potentially throw off the tuning they'll fix you up.

Thanks Gonk, I actually looked for inulation in the threads, never even thought that cotton might be the keyword. I will call anyway to let them know about the issue. Will post if it becomes a problem and I will let everyone know the resolution.
