Single driver vs traditional 3 way loudspeakers

Super tweeters make sound more refined, more air, detailed… But harsh in upper midrange, more fatigue, more smearing.


~~~~~~~~~~~~~~~~~
Yep I could not live witha  super horn tweet, Not my cup of tea.
I recall the old rat Shak super's,, just aweful,. Sure they are superior now, 
But I;'m going to try a  Scan Clone Be/Nd tweeter vs my 3 inch paper cone double magnet tweeter. 
My guess is the Be/Nd will annihilate my fav paper tweet.
Will run a single 2.2uf Mundorf SESGO cap.
Think this will kick in at 10khz ish..range

Hi @mozartfan ,
High-Pass filter and crossover are the same thing!
You didn't read my message. I told that 4th order crossover (HF filter) fixes most issues with super tweeter.
I have to add that in case of forward-firing super tweeter placement should be aligned with the speakers. It is true for any kind and order of crossover (HF filter).

The comment about all 3 way speakers being fatiguing in the long run is an incorrect generalization. I have lived with 3 ways that did betray their crossover points in use, but I also owned the Spendor SP100, and it was not the case with that speaker.

Hello @alexberger , also is very hard to add super tweeter to whizzer cone wide band drives, ih this case we have two tweeters - one mechanical -whizzer and other one electrical, we have to say by by one’
i say by by to whizzer tweeter and cut it down, I know some guys do it same and say whizzerectomia , may be wrong spelling

Hi @bache ,

Thank you for explanation.
I understand if you use full range driver you don't want to use it thought LPF.
With most of compression driver - midrange horn combinations high frequency response drops relatively fast and without significant peaks. So it is possible to separate frequency ranges between midrange driver and super tweeter if using 3-4th order HPF for super tweeter and don't need LPF for midrange.
     
I have a friend who is DIY speakers builder with many years of experience. When he built a number of JBL 4344 clones he always use 3-4th order HPF for super tweeter.
He told me to use 3-4th order when I bought Fostex T90a. But I didn't listen him in beginning.
And I now understand how right he was.

Regards,
Alex
