pgaron Posted February 6, 2007 Report Share Posted February 6, 2007 On the rec.audio.high-end Google discussion group, the following exchange took place in response to a question about the possible use of asbestos in vintage loudspeakers, particularly the AR-2AX:On Sun, 04 Feb 2007 16:20:12 +0000, zibbit wrote: >"I have been told and have been reading about asbestos used in AR speakers > (maybe others).

"Fiberglass does not contain asbestos, the two materials are completely different. In the US bans of asbestos started going into effect around 1973. Speakers made prior to that date could potentially contain asbestos. "This would only be a concern if you plan to open up the speaker and work on it. If left undisturbed and in a sealed box (AR speakers were acoustic suspension) it is not likely that the asbestos would be a hazard. It is when the asbestos becomes airborne that is becomes a problem." (***End of quoted material***)I was wondering (somewhat uneasily) if anyone on this forum knows whether asbestos was used in any of the early model Advent loudspeakers. I own a couple of the original, or near-to-original, Large Advents, and, like many of you, replaced the foam surrounds as a do-it-yourself project, so I'm curious what I might have been exposed to!pgaron Link to comment Share on other sites More sharing options...
jackfish Posted February 6, 2007 Report Share Posted February 6, 2007 The worst thing you were exposed to in your DIY refoam were the vapors from the adhesive. Link to comment Share on other sites More sharing options...
Doug G. Posted February 7, 2007 Report Share Posted February 7, 2007 This is a perfect illustration of why the "newsgroups" enjoy the reputation that they do.All it takes is one yahoo (and there are plenty out there) to pipe up and declare something and it ends up becoming "fact."Doug Link to comment Share on other sites More sharing options...
Guest wbz Posted February 8, 2007 Report Share Posted February 8, 2007 I havent seen any asbestos in my Large Advents, New Large Advents, or Advent/1s. Fiberglass, yes, but no asbestos. Link to comment Share on other sites More sharing options...
Guest 2Ear Posted February 14, 2007 Report Share Posted February 14, 2007 I think I spotted some plutonium in my LAs during a recent re-foam! Link to comment Share on other sites More sharing options...
