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 "Live Long and Prosper!" Michael N.
