1ajs,
We were discussing this set of speakers in another thread. The solution is to use Methylene Chloride if you can get your hands on it. It is the only real solvent for polyurethane foam, I was a molder so I know that for a fact. The problem is that it can and will attack the glue joint between the surround and the cone. What I remember from the other thread is that this one particular speaker has something wrong with the voicecoil and you are more than likely going to have to rebuild the speaker and replace not only the surround but the voicecoil assembly. If you are real careful you will be able to save the cone and use it with a reconing kit. There are a number of companies selling the components that you need to do this or if that isn't something that you are comfortable with there are a bunch of companies that will do it for you. Those are the 604E Altec's I am looking at right. You are the one that got handed the problem but you should be able to salvage the pair and make yourself a nice set of monitors.

It looks like they could still save the cone if you can carefully remove the urethane from the back side of the cone. Did you get the pair. I sure hope so. If you got the pair I would think you would want to save the cone, otherwise you would want to recone both devices at the same time or they will sound very different. They will still sound different for quit some time until you break in the spider and the surround as new they will be very stiff.
