Interesting article, but of course it is marketing and not sure I'm buying the value of the pitch completely. THere is no distinction between the hearing of young and old, which is generally considered to not be the same in regards to hearing high frequencies. I suppose the target demographic ain't the young folk. :^) |
It is not difficult to overlook the few paragraphs donated to what this man's company produces and how there, they all like the results of engineering and design that far exceed the 20kHz bandwidth. He presents the findings of many other scientists of why extra-wide bandwidth and low phase-shift reproduction are important. These are facts and science evidence of which any advanced audiophile should at least be made aware. Such as the concept of a coherent cylinder of radiation from original OHM speakers is a useful concept to know and more fun to hear. Definitely no BS in this article. Best, Roy The link I posted above once again failed to function just now as I tried it. However, I did finally find the issue with my typing, so once again: Enjoy the Music Article -OR- http://www.enjoythemusic.com/magazine/manufacture/0114/the_world_beyond_20khz.htm |
In previous forums I've commented on my hearing issues and questioned whether a good equalizer would help with my sensitivity to upper frequencies. Although I didn't comment on it, though, I've always felt that frequencies beyond audible range added, through some mechanics of harmonics I guess, to what I believe is referred to as timbre. I still think that to be the case so using an equalizer to merely minimize the offending frequencies would also diminish overall sound quality through elimination of frequencies beyond audible limits. For that reason I've abandoned this approach. The article referred to by Royj, (the world above 20kHz) even though I had difficulty understanding much of it, seems to address what I'm referring to. All of that being said, although I will look into issues that relate to my CD player and DAC as suggested by Mapman, I'm still concentrating on tweeter choices as at least one element toward potential improvement. I didn't have the problems I've discussed when I was using Magnepan or Focal speakers but, then, that was when my hearing was 15+ years younger. BTW, I borrowed a pair of small inexpensive floor standing Infinity speakers for temporary use while my Odysseys are out of commission. Although overall sound quality is only O.K., they are quite easy to listen to with very little high frequency harshness, and the reproduction of violin and cello is quite realistic and pleasing. My current thinking, based on my internet research, is that most quality tweeters are capable well above 20kHz regardless of design so there remains the question of why some speakers (and maybe it's not the tweeters at all) sound harsh in the upper frequencies. |
