In Reply to: RE: you've never heard of "cupped hands" distortion? posted by Inmate51 on February 24, 2017 at 21:37:01
My point is / was that the normal operation corrects the magnitude response which IS what gives the horn a "cupped hands" sound.
Yes there are other kinds of distortion too but they are all related to alterations of the input signal which can't be corrected while the mag response is easily corrected as it is mostly minimum phase and like i said the magnitude response is a product of the drivers power response and the horns directivity.

My view of a horn system's strengths and weaknesses has not changed much since the Trio Compact days. Oh, I've certainly heard great-sounding horn systems at various trade shows, including several in Munich just a few months ago. (And once again I'm not denying the unique virtues of horn-loaded drivers.) But I've also invariably heard traces of the "cupped hands" colorations and driver-to-driver incoherence that eventually wore me down and out when I owned the original Avantgardes. (I guess I should also note that because of the various phase, time, and frequency-response issues I've already mentioned and the sheer aggregate size of their wavelaunch, horn loudspeakers don't image with great precision— nor, since they don't disperse their sound hemispherically the way point-source direct-radiators do, do they typically soundstage "outside the box." Although the severity of these problems depends on the design of the horn and the level it is played at, certain horns can be as much the poster children for "six-foot-wide" voices and violins and guitars as vintage planars were.

again... i still don't see how this ENTIRE effing thread has been HIJACKED with talk about horns when i asked about RIBBON TWEETERS! (which, BTW, at 95dB or more also happen to be HIGH EFFICIENCY, and this isn't the "if you don't like horn tweeters, you suck STFU forum, is it?)
