Yes, this is the woofer in the G2 version I purchased for a bedroom system for my daughter. When I was testing them out, I noticed the woofers became loose when playing deep bass. I didn't want to go through the hassle of returning them only to possibly receive another set with the same issue. You can see that the MDF or pressboard they use does not hold the screws well. I just filled all the holes with wood filler and a small piece of a wooden toothpick and let it dry and then re-secured the woofers. So far it seems to have solved the problem.May have missed something here, but is this your Micca?
I had happened to take the picture when I took the woofer out so I though it would at least give you one view of the magnet which seems to be bigger than what is in the Gen 1 version of this speaker (at least based on the manufacturers picture below). In my picture you can also see that there is some insulation inside and the internal wiring is also in a sheath.
