Ralph, way wrong. There were great horns when Harry hated them.....Tannoys have been great for a long time, various JBLs were, horns were all over in recording studios sounding great.
Kiddman, I think you may have misunderstood my post. I happen to agree there were great horns when hp made that statement and one of my early customers was making Hartsfield reproductions which sounded great at the audio shows in the late 80s and early 90s. I was running Altecs with dual 15" woofers back in the 1970s... Anyway my point was with my last post that hp would certainly not say that today.
As far as contributions- hp created most of the vernacular we audiophiles use to describe the sound of our stereos- 'soundstage', the use of color descriptions to describe tonality ('bright', 'dark', etc.). He was one of the very first to describe the sound of equipment based on listening. Stereo Review and other magazines around at the time simply did not do that. Nowadays we take that sort of thing for granted. So his contributions should not be ignored even if you don't agree with his reviews. He had a serious influence on high end audio.
