Supertweeter for DTQWTII, yes or not ?

[academia50]

What do you think of this supertweeter?
Do you consider it a clearly noticeable improvement above the Audax TW034 with waveguide?
The report of the DTWTII builder says yes, but I don't know if he is a young person ...... gg, do you understand ?
On the other hand, I remember reading an article by Tannoy (when he launched the supertweeter for his classic line of coaxial speakers) where they showed (with measurements) that harmonic frequencies above 20 Khz favorably changed the tone of the frequencies that yes we can hear the common of mortals ......

Super tweeter? Have you seen GTR145 response? Especially if you listen it off vertical axis. RT850 would be a better choice if you want to go that route.

No, I have not seen it, should I consider the one you say as far superior?

You don't answer my question anyway, is it justified?

Here is a review that seems to be very complete ..... but I can't know what it says, I don't understand spoken English .... maybe someone could give me a little summary .....

We all value different things in music reproduction. A proper super tweet may add more air, space and maybe even dynamics, but how much it will depend on a particular speaker and implementation and of course how much you care for that . Yes RT850 would be a much better in reproducing the top end. So would many 3/4 inch (19mm) dome tweeters.

Oh and I have GTR145 so I do not need a review . It is a great tweeter if you like ribbons and it is more of a stand alone tweeter.

HiFiCompass is the best thing happened to our speaker DIY community.

HUmmm, both on the vertical axis and on the horizontal axis, begins to roll at 10 KHZ, it seems that it is as you say, it does not reach the category of "super"

But my original question still stands .....

Reading carefully, thanks !

I found the article and added another very interesting link, with measurements

" Despite claims over the decades, I have yet to see super tweeters considered "must have" features of most speaker designs. "


This seems to be the definitive conclusion ........

Point ?
