Default Refoam Kit Needed, where?

I badly need a refoam kit for my Sony APM 500 speakers... I've tried EBAY, some companies from the US and no one seem to have then, only 1 seller based in the Ukraine of all places has a kit and that kit only uses poor materials for like 50

Does anyone know of a place to order some from? I need both drivers reworked.

good luck with 30yr old proprietary shapes and sizes - your choices may be limited to what's offered, making your own (no doubt someone will have advice on that) , or retirement.

ask these people, perhaps they can custom make something

Good Hifi's speaker rings - foam, rubber and fabric for more than 3000 speakers.

In absence of a commercial solution and only choice is to toss drivers you might want to craft your own surrounds from thin EVA craft foam sheets. You can mold a half roll shape into them with a cylindrical shaped square donut made of metal. Warm up foam and form with heat gun. I have not done this myself but may try soon as I have old speaker a or worth the $40 price of new surrounds.

Fostex used rubber impregnated silk. Silk is available and you can buy liquid latex. Should be possbile to make a decent quality surround - just time consuming.

Sounds like a racing bike inner tube might work.

The corners might be an issue

I'm pretty sure you can vacuum form EVA foam also. It should be doable with some pretty basic home brewed equipment and a home oven, but it would need some carved molds and a bit of dedication.
