Frzninvt Posted February 15, 2020 Share Posted February 15, 2020 Louis Erath was a seismologist and had a very thorough understanding of low frequencies. The LWE-I's when mated to an amplifier with a Klip Kit were capable of a flat 20Hz to 20Khz. To find a pair with the custom LWE amplifier that was designed for increased negative feedback is like finding chicken teeth. Louis and Paul Klipsch were friends and he had a small speaker company in Houston I think it caught fire and he eventually sold it off to Acoustron. CM Labs developed the 911 that was also custom designed to run the LWE-I's. His circuit was so secretive that he placed it in a metal can and filled it with epoxy so that it could not be copied. The plant stain on the one looks like it can be removed with a moderate amount of effort. He did use real wood veneers as well and the equivalent woofer to the K-33 with custom parameters. He also was good friends with the creator of Parasound if I remember correctly. Either way imagine better than Cornwall and Klipschorn performance out of speaker just a bit bigger than a Heresy. They connect via Cinch-Jones connectors because of the negative feedback loop to the amplifier. I sold a pair to Gary (I forget his user handle) on this forum years ago and I pointed him to a CM Labs 911 version of the amplifier and was thrilled with it's performance. There is much more to the LWE story and the price is certainly comensurate and I am sure someone could possibly talk him down some. Very worthwhile checking this set out as you will never see another LWE amp that I can assure you. https://www.ebay.com/itm/Vintage-Acoustron-LWE-LoudSpeakers-and-Amplifier/333497889448?hash=item4da605f2a8:g:ZNUAAOSwHU9eMJmR 2 Quote Link to comment Share on other sites More sharing options...
avguytx Posted February 19, 2020 Share Posted February 19, 2020 I had a chance to buy a pair of these before I moved from Texas in 2009. I wish I would have gotten them but I was at a downsizing point and going back to college at 43 to start over. 1 Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted February 19, 2020 Share Posted February 19, 2020 Looks like a Heresy tweeter in there. Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted February 19, 2020 Author Share Posted February 19, 2020 Yes that is an EV T-35/Klipsch K-77 in there. The woofer was made by CTS and has a square magnet like the K-33 from the same era. The cone midrange has excellent vocal output and has a sealed back if I remember correctly. Lots of adjustment on the back. Quote Link to comment Share on other sites More sharing options...
