[QUOTE="Tzs503gp, post: 1117060, member: 19443"] Watch this video [USER=25509]@Sarel.wagner[/USER] As I understand it, energy beyond 20kHz helps define tone, timbre, location and other physical traits. We do not “hear” those frequencies. One might think of it like a polarised filter. You do not “see” the filter, but it has a remarkable effect. Unfortunately, the equipment before the super tweeter becomes all the more important. Frequencies beyond 20kHz are not the domain of most HiFi gear. The phase relationships of the fundamental to these high harmonics is ultra important. Most amplifiers simply aren’t designed to be phase coherent at such frequencies. Not to mention the myriad other issues along the system chain. As an example, cables: theres a strong argument that LCR effects, when reasonably small, cannot affect what we hear, in the audible frequency range. Meaning: yes there are differences in cables, but at the frequencies we hear, the difference is inaudible. An argument which has merit. Now, model those LCR effects at 60kHz…. Which brings me to my line. The idea of the super tweeter has merit. Good luck finding upstream equipment that can keep up though. [MEDIA=youtube]UrBZsUBibtk[/MEDIA] [/QUOTE]
