Advent Loud Speaker

Cayuga

I'm going to start a restoration project on my Loudspeakers, I just received two replacement woofers (1975 Advents). I'm looking for products and procedures to seal the woofers. Please give me the what and what not to do. Thanks

There are some serious speaker builders/rebuilders over on the Parts Express forum that've helped me out more than once, you might inquire there also. I love the old "vents", fried eggs anyone?

Thanks for the tip gdb, I'll take a look. I know people in this club have changed out drivers, I'm just looking for the correct materials to use for a good seal.

ahh, to seal the cabinet to be airtight?
PartsExpress sells nice stuff for that (they used to provide a hank of it when you bought a speaker from them; dunno if they still do).

(the 36" length of stuff at the bottom of the short list is what you're most likely looking for).

I initially thought you were asking about sealing/treating the foam surrounds; silly me...

Thanks mhardy6647. I'm sorry if my question was confusing, I just want to replace the woofers and make sure they are tight.

I am listening to a pair of OLA in the bedroom system right now. I found this article by Frank van Alstine where recommends coating the inside and the speaker frames with non-hardening plasticlay.

He suggested using plasticlay as a sealant to decouple the speaker from the front baffle. I am going to try this on a pair of Monitor 5's I am about to recap.
