Check out partsexpress.com – I ended up replacing the woofers from my mom’s really nice speakers with some from there. I’ve heard it’s not too bad to replace the foam, either. I think they sell kits for that, too.

You could always just spray some Silly String in there. Just make sure you use the hot pink color – smells better!

I’d be happy to laser cut you a set if you have the foam and dimensions. Not sure if they’re exactly flat, probably has some kinda molded shape. Anyway, just let me know.

Replacing the surrounds is incredibly easy.

Ironically I just reformed mine. It’s not time consuming (well, only slightly). and you defiantly have the skill. Your work speaks for itself.

You’ll only need the new foam surrounds (I purchased a set on ebay). Make sure you get the set of 18. I only paid 10 dollars. for the foams, and about 3 to ship.

-AND-

A bottle of you general crazy glue. Plus some q-tips to smear it with, or a paintbrush.

The front cover will need to be pried away gently until the staples detached from the plastic. There is exactly 9 drivers per speaker.

I took my crazy glue and mixed it with 2 parts glue, one part water, in order for it to be smooth enough to spread with a paintbrush.

First, line up the foam with the inner cone. Then paint inside the cone and inside the surround in the center. Once it is painted with enough glue you can see some white, just push it over the edge of the cone until it begins to hold. Make sure it is centered.

When it dries in about an hour you’ll lift the edge of the foam and paint under it until it’s white enough. Press the edge firmly down. Use a cup to make sure the edges are firmly attached.

Test the cone while the glue is still wet. Press it in and out on the dome. If you hear a rubbing, adjust the outside edge of the foam until it goes away.

If you let it dry with coil rub, it will destroy the driver with regular use, and will sound horrible.

I put all the screens back on with double-sided 3M foam tape.

If you want to see mine, I’ll post them on flickr tomorrow.

I hope this helps you. I’m really happy to see someone who keeps some of the best speakers ever made around. I do have to ask, do you still have the stands and the EQ for them?

If they’re awesome speakers, I know exactly what I would do in this situation.

Not. Try. Fix. Them. Myself.

Same thing happened to my 901’s. They sell kits to replace the foam and is very easy to do. Maybe a couple hours per speaker to clean up the old foam and re-glue.

I bought a pair of the latest 901s about 5 years ago. I seldom use them, maybe once every week or two. Lately, I’ve been hearing scratchy sounds from them and my son said that he read something about the foam inside deteriorating after 3 years. These speakers were very expensive and are very precious to me. Any leads as to how I can get them repaired would be much appreciated. Or should I contact the company instead ?

yeah I have done hundreds of these, dont replace the drivers it will change the nature of its sound, thats my 2cents worth

they made these speakers in house. contact them, they have thousands there
