Roy Delgado, the fellow who worked along side PWK, and the guy now running things engineering wise over at Klipsch, has stated many times in articles, that he would keep the original Heritage designs intact, as they are wonderful designs, and still, as jsautter has stated above, successful sellers after all of this time. Also, to keep the legacy of PWK going. I never found any 2-3 wpc amp, to drive any of these models, properly. Definitely got volume out of them, but nothing to write home about. I know George is not a fan of Klipsch, nor horns for that matter, but I think that is fine, because variety, and individuality, is what this hobby is all about. Have a great day, everyone, and, Enjoy ! MrD.
