Here's my story...

About seven years ago I discovered that the surrounds on the woofers in my
girlfriend's Cerwin-Vega's were literally rotting away. I did some checking
and learned that this was an all too common problem because virtually all
of the loudspeakers made during a certain period of time had polyurethane
surrounds and the stuff just rots after a while (sort of like that foam
behind the front panel of the MG-1 only not as hideous).  I looked in the
ads in the back of Stereo Review (in those pre-Google days) and there were
a dozen places selling repair kits for $20-25. The actual repair was
straightforward but a somewhat nerve-wracking PITA. I had scrape all the
old glue off with razor knives and the sharp edges of the baskets tore my
hands up in the process, plus I was scared to death of damaging a cone. But
in the end it all went like the instructions said and today they sound
great again.

So the next question is "do they still sell those kits?" because all of
those speakers with rotting surrounds should had died by now. I just
Googled "surround repair" and got lots of hits. The very first place has
the whole kit for $19 and it looks exactly like what I used back then.

I guess people still damage them while moving loudspeakers and whatnot...
