Imo it is a mistake to assume that there is a good match between exit angle and entry angle just because the same manufacturer makes both. It seems like the compression driver department and the horn department often don’t see the need to collaborate.@audiokinesis Thanks- IMO this might explain why there are so many different reactions to horns. When I bought my speakers, I listened to both the TAD machined horn (at the time- this was 1998) and the JBL tractrix horn, both with the same compression driver. I preferred the JBL at the time. Later (about 10 years later) John told me that he had found and corrected a flaw in the throat design of the TAD, which is why he makes his own machined wood horns now instead of buying them from TAD. And in listening it did seem that he had made a very significant step forward in the sound of the speaker- it was noticeably **smoother**, easier to listen to at high volumes, even better than the JBL tractrix horn. In my old listening room I was able to easily play my speakers at 105dB and they sounded completely relaxed; if not for the sound pressure meter you would have no way of knowing they were that loud (which to me is an important hallmark of a good stereo).
Thanks again for your comments!
