Spider removal... any tips?

[wwenze]

So I need to take out the cone of this pair of speakers so that I can vacuum the dust out of the space between the voice coil and the magnet, maybe smooth up some rough edges (long story...)

So far I'm managed to do everything but the last step, which is seperating the spider from the frame, after which i can remove the cone together with the spider to access the magnet.

It seems easier said than done; there is like more than ~5mm worth of the spider's outer edge attached to the frame using brown glue, I can't find any place to poke my knife in to cut the spider off the frame.

And tips?

Or would it be possible to remove the cone from the spider instead?

Spider removal... any tips?

Raid?


If you remove the cone from the surround, maybe you can go in that way?


Cheers!

K I'll try lol, scared maybe later cannot glue back.

Maybe Rogers Studio 3 isn't the best speaker to try out reconing first hand.

You need to soften the glue holding the spider to the frame and then the cone assembly can be removed. I have used acetone or paint thinners brushed on but you need to be careful. You will also have to desolder the leadout wires.

ACETONE AND THINNERS ARE HIGHLY FLAMMABLE AND DESTRUCTIVE TO MANY MATERIALS.

And then there is reassembly and alignment.........

Maybe you should find a speaker repairer who could do it for you.

When I reconed speakers, I would pull off the cone (or cut through the surround), cut the tinsel wires, then poke an exacto knife through the spider at the inside edge of where it was glued to the frame. Then run the knife round the inside edge and you can lift out the cone, coil, and spider assembly. Then I'd use acetone or similar nasty stuff to soften up the glue before scraping off the remains of the spider and cone. I'd also cover the voice coil gap in tape before doing the scraping to prevent more junk from getting in there. How much of a pain all of that is depends on what glues were used to assemble the speaker. With some glues, heating the speaker to ~120 degrees F will help soften the glues so you can peel things off, but other glues will be completely unfazed by this.
