Denon DHT-591BA - removing plastic tabs from speakers

So, recently picked up this system, and each of the speakers has a small clear plastic tab, about 2 inches long, thin material, that comes out from behind the grilles in the lower right corner. I'm not sure how to best remove these without damaging the speakers or grilles. It's not obvious to me what the best method for removing the grilles is, and I can't find any information about this in the manual or through numerous google searches about these speakers.

Anyone know?

Thanks.

Exactly, this was the only bit of information I found relating to it, and like I said, I don't know the correct way to remove the grilles. I'm at work right now, when I get home I'll take a picture and post it. I'm surprised more people haven't asked about this. When a speaker grille is inset flush with the speaker box, how would one normally go about removing it?

I just want to remove these strange little plastic tabs that are protruding from the bottom front of the speakers, they seem to be attached to something beneath the grille. I have no idea what their purpose is.

So, the solution is, pull forward on the tabs, fairly hard, so that it pops off that corner of the grill, the tab is secured around the little rod that holds that corner of the grill attached, when it pops off, just remove the tab from the rod, and reattach the grill.

Just pull firmly back on the tab, towards you, dislodging the bottom of the grill, then remove the tab.
