is there any way to freshen up older dry speakercones

leftwinger57

After getting the Bose 601s for $20 w/ the surrounds totally dried out and in need of a refoaming I was wondering if there was process that could bring back the speaker cones themselves.I personally never heard of this but ever since I learn crap here every day I was wondering if this is a practical way of extending the life of the speaker even more than just refoaming.If anybody knows ,pass the info because I could use these for another 20 years if they do respond to whatever treatment if any.I tested all the drivers before ordering the foam kits and they all worked so the off chance that a treatment does exsist would be benificial in so many ways.I was on the web and series 1 601s are regarded as the best in the series even if the other models look better and I think they do but for the price I got them for and the the foam kit and the labor I think I have a winner here.Please guys do some research and see if there is any speaker rejuvination juice to bring them back close to factory specs.Thanks again and whether or not you approve of Bose ,right now is inconsiquential because I have them and they are staying unless the sound is so bad I will dump them back to Goodwill where I'm sure someone would snatch them up toot sweet.....

I dont think you really should worry to much about that... I have seen speakers (Advents for example) that are... jeez 40 years old at this point and the cones are fine.

Have to agree. I have quite a few speakers in that age range. The ones with the rubber or KLH treated fabric surrounds are still fine. Things like my Advents have been refoamed but the cones are mint! And they're certainly 40 years old!

You're good unless that Bose paper is not up to snuff! lol

Heck even my old Dynaco A25s are minty (original surround there).

Didn't you see how they sounded before ordering the foam kits ? Just curious is all, you'd probably do better on craigslist for 50 bucks.

Maybe these for 80 bucks

601's are alright for Bose. They will not have near the highs that any of your current speakers have. They have good mids and decent lows though.

I have never heard of treating the cones on speakers. There is some stuff that the Transmission Line guys do to there speakers, but I don't think it would work for the speaker in the 601.

That said, a good refoam will do a lot to keep them running for many years to come.

I also forgot to add. I have heard but never tried Scotchgard. I believe the idea is to use outdoor grade scotchgard to protect the speaker. It should have very minimal effect to the sound but would make the speaker less susceptible to moisture.

Like I said, I have never tried it.
