Giving old spreakers some TLC

[TIMBO]

Hi guys, The Fi Sonic amp came with a 2x12 speaker cab (approx. 48years old) which is getting a much needed face lift and now I need to tidy up the speakers. They look in good condition except the gaskets(cork) and I don't think that I would like to try and replace them. I there any thing that can be done to fix them up a bit or will they mount ok as they are.
The cones look to be in good shape, one has a small tare, can this be easily fixed. Other than that is there anything I need to do before I subject then to some horrific guitar playing.

we would use finger nail polish on small tears in woofer cones back in the day.seemed to work fine but i bet there are plenty of better ways.i've seen vids where a small patch is glued over the hole.any method you use though i think it needs to be applied to both sides.and if most of the cork is there i would let em ride that way.as old as they are the more you mess with them the greater the chance is of worsening the condition.also the older a speaker is the less power it can use.i read that some where on the web more than once so it has to be true lol.

Wow!  A whizzer cone in a guitar amp speaker?!?!  Never seen that outside of a stereo speaker.  I always used rubber cement for tears.  But like Slimtim said, I'm sure there are better products out there!  You just need to quit sticking broken guitar necks through it during your performances!  Seriously, I have some radio hack guitar speakers from the 60's that are still thumping.  Of course it certainly depends on storage conditions during its down time.  Just don't do 20 minute feedback sessions through them with your Marshall Super Lead!

Yeah they are pretty cool, although there is no recordings of what they sound like 

I ended up patching it with a piece of paper hand towel and PVA wood glue as it was only a small tear about 1/2" long and wasn't really torn right through more like a dent.

I used a fine metal file to dress up the cork gaskets that flattened out some of the bumps and looks better and will seat the speaker better, should I seal the cork before I bolt them in??? Thanks
