Am interested in buying a pair of older Heresys (they sure hold their value judging from the prices on ebay). Did the drivers change over the years? If so, does anyone know the nature of the change, the year(s) of the change(s), and the serial number at the changover point? Thanks, Brian P.S. Doe anyone know a Klipsch dealer in Canada who might have older Heresy's as trade-ins?

William asked about my situation and expectations: I have been an audio enthusiast and DIY tinkerer since my teens (30 years ago). A recent interest in horn speakers (why now after all these years...?) sent me to this forum as well as Audio Asylum's high effieciency BBS & forum. After some research, the purchase of a pair of Heresys or Cornwalls seemed like a good place to start. I live in Toronto, Canada and Heresys on ebay would cost almost $1000 CDN given currency conversion and shipping costs. The DIY route suddenly became more attractive. Understanding that Klipsch will sell parts, I am trying to identify a cost-effective Klipsch midrange tractrix horn that could become the foundation of a mordernized DIY Heresy. The interest in tractrix came from reviewing my stash of old magazines and periodical clippings such as Bruce Edgar's Speaker Builder articles, and the Audio Magazine article on Tractrix by Klipsch researchers. What intrigues me about these older speakers is the wide frequency range covered by the midrange driver coupled with the low crossover frequency. I would like my DIY speakers to have the same characteristics. I am hoping to get some suggestions about cost-effective drivers, either from Klipsch or other vendors, that I could use to build a DIY speaker with superior performance to the Heresy or Cornwall. Any help would be appreciated. Brian This message has been edited by BrianG on 12-08-2001 at 12:28 PM

For and old Heresy, is it possible to replace both the squawker & tweeter with a tractrix horn that will cover the range from 700 hz to 17 Khz? Is it worth doing? thanks, Brian
