Post Subject: What is sound of Twitters?Posted by Romy the Cat on: 7/29/2011

Actually Jorge brought a valid perspective: the HF that are crossed at 5K are not the same as HF that are crossed at 10K. The point is that in a playback that crossed at 5K one can’t talk about HF as a self contained expressive tool as in that type configuration a person has no control over HF. In my definition HF is the frequency without which playback can play perfectly fine. Jorge crosses at 10K, I at 12.5K… there is no magic number and it all depends from many things like room, topology, drive, loading etc… Still, the main frame of sound shall not be formed by tweeter and this why I feel that haralanov’s illustration above regarding the changing of the presentation window shall not be affected by tweeter alone, at least not as much as haralanov depicted.

BTW, in the subject of integration of tweeters it is VERY important to have the TTH characteristic match between MF and tweeter, this is my few is super important and it very seldom paid attention to. People like to talk about good quality of tweeters but they never understand that it is not about the quality of tweeter itself but about the match the specific tweeter to the specific MF driver. I have written about it many times but I did not see it got any traction among audio people. I quest they need time to ripe…

It is certainly very very important, but how many systems you have listened where you can not be able to recognize the HFs as disconnected part of the sound? I just wanted to ask if you have ever heard a system, where the sound of the tweeter is COMPLETELY part of the midrange. I know there are a lot of people who insist they integrated their tweeters perfectly, but when I visit those people, I can always identify the sound of their tweeters.

…it would be interesting to let you Haralanov to hear my installation as it is today and to hear your opinion about HF integration in today’s Macondo. I do not insist that it is good or bad but I can assure you that it is a bit different then what you might accustomed. I can’t not explain what the difference is (you need to hear it) but I do have option to change the integration schema literally on fly. If you find yourself in Boston then I can try a few integration schemas and if you tell me whish one you like I think I will be able to tell you precisely what specifically annoys you in sound of tweeters.
