I don't have Electro Voice speakers, but I too have an acoustic suspension
speaker that the surround suspension had died.  I tried to repair it,  but
it just kept tearing.  Finally, I just pulled off all  of  the  suspension
foam.  It plays, but not very well.  

My speaker is an Advent circa 1974.  It too has a 10" woofer, but is built
on a 12" frame, so this woofer may not fit your E-V's.  Anyway, I wrote to
Advent.  They will sell me a woofer to replace my old one.  Seems a  shame
since my woofer cone seems fine.  It would be simple just to  replace  the
foam, but there wouldn't be any MONEY in doing that.  At any rate, I  will
order the woofer and replace it.   Meanwhile,  I  have  a  perfectly  good
speaker without the foam surround, doing nothing.

You may wish to check with Advent to see if they would sell you  a  woofer
if it will fit your enclosure.  They are in Illinois and are  a  subsidary
of Jensen International.  Address:

   Advent Division of Jensen
   4138 North United Parkway
   Schiller Park, Illinois  60176
