owlsplace Posted June 4, 2015 Report Share Posted June 4, 2015 I saw a pair of LST's in original boxes on the auction site yesterday complete with refoamed woofers and a demo video. They disappeared very quickly -- must have got an offer he couldn't refuse.Anyway, since there seems to be so much, or considerable interest in these rare birds I am wondering if doing a reproduction is feasible.It looks like someone may have made a "one-off" cabinet in the past unless AR offered "unfinished pine" (added: but those don't look like AR woofers).The only possible drawback I can see other than finding suitable drivers would be hand-winding the auto-transformer.Any opinions? Waste of time? Time to move on, etc. Klaus, Carl, Roy?Roger Link to comment Share on other sites More sharing options...
Carnivore Posted June 4, 2015 Report Share Posted June 4, 2015 Yeah, somebody snapped up those fantastic AR-LSTs in original condition fast, for $2,200 + shipping, using Buy It Now. I suspect that seller could have done a lot better with an auction. You can only judge so much from a YouTube video of speakers playing music, but it sounded like those tweeters were working well. Nice score for whoever grabbed them.Where did you see those pine cabinets by the way? Link to comment Share on other sites More sharing options...

owlsplace Posted June 5, 2015 Author Report Share Posted June 5, 2015 Looks like RoyA mentioned tri-amping to eliminate the autotransformer here: http://www.classicspeakerpages.net/IP.Board/index.php?showtopic=4198Probably not alot of people would be interested in doing that.Also, it is obvious from this thread that a few people seem to have unresolved issues centered around the Acoustic Research Laboratory Standard Transducers (AR-LST): http://www.classicspeakerpages.net/IP.Board/index.php?showtopic=2002Might be worth doing a repo for that reason alone Roger Link to comment Share on other sites More sharing options...

The LST remains an anachronism in the history of audio reproduction."I am selling my AR-3a's and LST's to buy Allisons" from a review that appeared when my audiophile days were at an end due to the natural progression of life events.The review is at the end of this document: http://www.bostonaudiosociety.org/pdf/bass/BASS-03-10-7507b.pdfRoger Link to comment Share on other sites More sharing options...
