I didn't see a thread here on refoaming tips and tricks so here goes. Please add on any methods that you use.

You can pick up foam surrounds from a number of sources. I use eBay.

You will need to remove all of the old foam from the cone (it should just rub off with your fingers-- don't use a knife.). Also, the old glue will need to be removed from the basket. I use a Stanley Utility knife to scrape it off.

Aleen's tacky glue works pretty good for installing the new surrounds. (Available at a fabric store.)

Keep your fingers clean. Use a wet cloth/paper towel to wipe off any glue.

Test fit the surround before gluing and just make sure it will work with your speaker.

Put a small bead of glue on the front outer edge of the cone and the back side of the inner ring of the surround. A bead 1/16 inch wide should be enough. It's better to use less than more, you can always add a little where needed. Use a Q-Tip to smooth the glue out so it covers the outer edge of the cone (generally about 3/16 inch) and the back side of the inner edge of the foam surround. Let sit for a few minutes.

Place the surround on the cone and position it so it is centered. You will be able to move it around until you get it correct. (I try to use the area where the old glue was as a guide.) Then apply pressure by using your thumb on the front of the cone and middle finger on the back of the cone (I reach around the basket to get to the back side of the cone.) Check the outer edge of the surround to make sure it is centered as possible using the outer edge of the basket as a guide. Work all the way around until the glue sets. I use a Q-tip with a little water to wipe off any excess glue that squeezes out. Leave this to dry overnight.

Apply a bead of glue to the basket and the back of the outer edge of the surround and use a Q-Tip to smooth it out. Then start working the outer edge until it sets up-- apply pressure again along the surround and outer edge of the basket until the glue sets.

While doing this, make sure the voice coil former does not rub. Gently move the cone up and down and listen carefully for any scratching noise. Rotate the speaker when doing this so you check multiple points. If you hear a scratchy sound, reposition the outer edge of the surround one direction or the other until the noise stops.

Once the glue sets up, I then give the speaker a -*test*-('") with a low level bass signal (Use a CD with some good bass) to make sure it sounds right.

Let the speaker sit overnight and then reinstall.

not all surrounds are created equal. some speakers require specific non-generic surrounds, and even a generic surround of the right size may not have the correct thickness or pliability. a great resource for surrounds is our own Reedger. if he has the correct surrounds (and he usually will) you wont find a better price anywhere.

I´m sure someone posted a link to a great video with a guy carrying out a full refoam job.
