bailecz Posted May 4, 2021 Share Posted May 4, 2021 It seems my Khorn experiences some distortion at certain frequencies / tone while listening to music. Id say the problem area is in the mid range. Very difficult to discern. My problem is Im not sure of its source....mid or hi horn. (I fairly certain its not the low freq woofer.) Even placing my ear close to the horns leaves me uncertain. 1) Any ideas how to find the source? Maybe thru a strategic process of DIY elimination tricks? 2) Could a bad diaphragm cause this? My components are: (Hi-Crites CT125, Mid - Atlas Sound PD5VH, x- B&K Type A/4500) (Parasound A21+ P3 Preamp) Quote Link to comment Share on other sites More sharing options...
Schu Posted May 5, 2021 Share Posted May 5, 2021 You can unplug the drivers and listen to the source material one driver at a time to help nail down the issue, if there is one. Sometimes it's merely the source material as it can be exacerbated by the revealing nature of a klipsch speaker. It could also be a capacitor going bad and leaking.

Frank1938 Posted May 5, 2021 Share Posted May 5, 2021 Are you getting the distortion in both speakers? If so, be assured of a good source by trying a couple of CDs that you know to be of good quality. I would be surprised that it is a crossover if distortion is in both speakers. If it is in one speaker, try what Schu suggested but disconnect one speaker at a time to isolate the sound. 1 Quote Link to comment Share on other sites More sharing options...

boom3 Posted May 9, 2021 Share Posted May 9, 2021 The K401 midrange mouth is too small, that's the root cause, and the topic has been discussed in this forum for years. This is why the Jubilee uses a much larger midrange horn. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted May 9, 2021 Share Posted May 9, 2021 I thought the mouth was okay once mounted on a baffle. I always thought it was the narrow throat. John Warren called it “throat overload compression”. However, I never had a problem with that horn except at very high SPL, and actually preferred it at most listening levels.
