JBL L110 Grills

All, need to replace the fabric on my JBL L110 speaker grills. Anyone have any idea how to disassemble these grills? or can they be disassembled without damaging them?

Thanks,
Dave

I have been able to get the frame apart using a utility knife with no damage to the parts. It is not easy. There is much prying, pushing, slicing and cursing. I pressed it back together after installing new black cloth.
