[Cloth surround sealant]

Hi, they are little Goodmans Maxim 1 speakers from the 1960s. I've been in contact with all of the major refoam kit sellers I can find without any luck. The surround measures something around:

4.25"/ 110mm full outside diameter

3.75" / 94mm diameter of outside edge of half-round profiling

2.75" / 70mm diameter of driver cone

2.25" / 58mm inside edge

0.5" / 13mm half-round profiling width

Roy,

I'm going to have to feel my way on that. I'm going to try linen pressed over a mold and a lot of steam, as Tom describes, and also polyester and a heat gun. I've been browsing "permanent creases" and PVA and resins are suggested but would be a last resort.

The surrounds on the drivers I'm trying to fix look synthetic. They are awkward in having a wide half-round profile versus their diameter, I presume because they have very long throw magnets and so a lot of movement. The one has the original surround that has gone completely slack and the other has been replaced with foam which is stiff and doesn't let the cone to move much. I've had no luck finding foam surrounds that come anywhere near the dimensions and profile so am trying to get close to the original design and materials.

Great information, many thanks. I've ordered the Vintage-AR sealant so will give that a go and will start playing around with some fabric to see if I can get it to hold the required shape.

Thanks, I'll give it a try, just the mental barrier of paying more for the postage than the item.

Any thoughts on the type of cloth to use? Polyester was my guess so that it doesn't age too quickly.

Thanks!!! I was minutes away from buying the Permatex. I'll have a look at the Vintage-AR sealant but unfortunately I'm in Europe so the shipping is bound to be painful.

Hi, old topic I know, but new for me. I see that Permatex High Tack Gasket sealant was recommended after much careful testing a few years back. Is that still the suggested stuff to use?

I'm going to need to make new cloth surround from scratch, so suggestions for the fabric would also be welcome.

Thanks
