Thanks i find this link, but i see this 4inc speaker, in google i see JVC PC-5 speakers is 4,5 inc?Scroll to the bottom of this old PC5 refoam tutorial, the link for buying foams still works.
Google says PC-5 4.5 inc not 4inc..4 in. Speaker FOAM SURROUNDS , fits a 3 1/16" cone diameter, small roll, mid | eBay
Remove the gasket and rub off old foam, apply glue to cone. center the surround evenly as you place it on cone.www.ebay.com

ThanksI mean narrowing these down just takes measurements so it's work so now you know what to do measure your speakers. I'm pretty sure these are 4-in woofers I haven't seen any 4.5 inch woofers on a JVC it's either 4 inch or 5 in. and I know they're not 5-in because the pc5 has smaller speakers than the pc55 and the PC 55 has 5-in speakers.
