I re-rolled my magnat main floor speakers years ago. Looks like the place I got the kits from are no longer in business. Just get the dimensions that you need and you should find a kit that fits or is close. Quite and easy job especially since it is only one speaker. Did find this place in my quick search: https://qsr.net.au/product-category/adhesives-glue-packs/ The other thread I talked about it last time: https://forums.overclockers.com.au/threads/speaker-repair-in-brisbane.588182/ That was a while ago now and my speakers are still going great!!!
