Beovox CX100 front fabric frames

Started to renovate a couple of old Bang & Olufsen Beovox CX100's, but did not want to discard the old fronts in case something went wrong or looked weird.

I replaced the original fronts with these I printed and fitted to the speakers wrapped with flexible jersey material bought at a local fabric shop.
