I have done a couple of these successfully, and it's really no big deal - it's actually rewarding to do it yourself. So here's my 2 cents:
1. You cannot "just glue on new surrounds". You either have to remove the dustcaps and shim the voice coils OR you have to use a "live" technique of playing a low bass test tone through the woofer as you do the final glue. This technique is very easy and fully explained in the surround kit that I'm recommending next in section 2.
2. You should use a quality replacement surround that has the proper, larger "roll" diameter. The original Advent roll was larger then the typical speakers of it's day.
I STRONGLY recommend buying these from a guy on Ebay whose handle is "looneytune2001". He's got very detailed, practically foolproof instructions AND he also provides very helpful email support if you should need it - which I did. (I have no relationship with him.) His "kit" comes with all you need (except for new silicone caulk to put around the woofer rim when you reseal it to the cabinet). His is slightly more expensive than others, but I initially ordered my first surrounds from elsewhere and it was a disaster. Here's a direct link to them (assuming Audiogon allows links): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=3276&item=5719250021&rd=1&ssPageName=WDVW
3. You SHOULD glue the new surround to the INSIDE of the brown masonite ring. (It's more trouble because you have to remove the woofer from the cabinet.) Any deviation from the original conformation will compromise the quality and longevity. If you glue to the outside you will be starting the "throw" of the woofer in a slightly advanced spot with tension on the spider that is incorrect and it won't sound the same. And if you used any typical small roll surround and glued it outside, Yuckkkkkk.
4. If you do this right, the woofers should be good for another 15 years.
Hope this helps.
