Can somebody tell me what the inside of the M60v2 speaker looks like and what the best method would be to retrieve a small toy my son tossed in through one of the rear ports?

I'm re-building my home theater this weekend (new TV, components, speakers, etc.) and noticed something rattling in my right speaker when I was moving it. I'm pretty sure its a toy that he placed in one of the rear ports - most likely the bottom port on the back.

Any thoughts? Is it safe to leave in there or would I experience some possible resonance? Should I remove one of the drivers? If so, which one? I'm certain that the M60 has multiple internal cabinets isolating the mids from the tweeters and bottom woofers.

Help!
