The Multicells HF Horns
I know that tweeters is a “lost subject” and it is hard to talk about tweeters with audio people. Everyone understand tweeters differently, primary in context of this systems or even more correctly – in context of this frustrations with thier current tweeters. I’m not an exception from those rules. I tend to use “talented” midranges and I do not anticipate tweeter to ”do” a lot. It is know that I have a bias to vintage tweeters with plastic diaphragms but here is not a conversation about the tweeters but rather about the tweeter waveguide.
I wrote before in the article “Problems with horns: tweeters” that I like wide dissipation tweeters, and considering that I use them way above 10kHz I would love to have a dissipation pattern as large as possible, 180 degree is better then 120 degree. Despite that I do have a tweeters about which I feel very comfortable but there is one tweeter direction where I would look with qureacity.
I heard a few times large 18 sections multicell midranges and it is not that I liked them but it was kind of fascinating effect, and particularly in far-filed. Altec has a number of 1803 sand-filed versions and I know Vitavox and RCA did the similar. They were huge, heavy…. and sort of mid-rangy… but I wonder what would be if to apply the same concept to a tweeter?
Romy, have you not seen the Duevel horns? 360 dispersion.
It's easier than 48 or 64 tweeters arranged multicells fashion:-O
Sure, I heard, they always sound quite awful and they are an illustration of a wishful but wrong thinking. First of all their tweeter are curved (!!!) into…. something that could be only theoretically called a horn. What was in the mind of a designer who decided to put a 90-degree curve into the tweeter wave path I have no idea!
