Dali Speakers in their kore speakers technology like Epikore/Rubikore should have what purifi want to achieve. I think they use same tech for the woofer and they use hybrid tweeter to achieve wide desperation with over size dome.
It's easy to not get things quite right, because the history can be complicated.kore speakers technology like Epikore/Rubikore should have what purifi want to achieve. I think they use same tech for the woofer and they use hybrid tweeter to achieve wide desperation with over size dome.
I read purifi tweeter P1 & 2 and they emphisys about achiving very wide despertion which also I think will be good. This were I see Dali also want to achive but each is taking his own path.It's easy to not get things quite right, because the history can be complicated.
If you are talking about the hybrid tweeter module, the goal is extension down to lower than what a typical 25mm dome can do eg. enable lower crossover point to the midrange. But a very large soft dome won't play past 20KHz, so a ribbon tweeter is used in the top octave. The upside is constant directivity/ dispersion once the ribbon takes over.
This hybrid tweeter strategy is not new. In fact it has been used by DALI for over 20 years.
If you are talking about the new 35mm soft dome tweeter manufactured in house by DALI, and used in the KORE speaker, one of the goals was for a linear frequency response at 25° to 15KHz. A ribbon tweeter comes in above 12K5Hz.
The Epikore 11 and other Epikore/Rubikore came later, with thanks to transducer veteran Claus Futtrup.
Lars' and Carsten's goals for what "purifi want to achieve" with their tweeter is different.
Yes it is larger dome, but there end the similarity. It's easy to be drawn into the size- but that is only one dimension-
all the other dimensions are equally important, and have been meticulously optimized by Purifi.
It has a wide and constant directivity from 1K5 to 20KHz and ultra low distortion.
In my analysis, this tweeter is comfortable with their 6.5" but also 8", and 10" PTT woofers, when matched with the appropriate waveguide/faceplate/cabinet shape (IMHO)
But we don't have to assume what their goals were- here they are:

No. The Purifi woofers are much more advanced than any Dali wooferI read purifi tweeter P1 & 2 and they emphisys about achiving very wide despertion which also I think will be good. This were I see Dali also want to achive but each is taking his own path.
But the woofer tech were I think they are almost the same.
here are measurements of a Dali Rubicore 6. It shows drastically narrowing dispersion above 7k. BTW why do you find that our woofers are similar?I read purifi tweeter P1 & 2 and they emphisys about achiving very wide despertion which also I think will be good.

They're probably referring to the part of the motor system with the soft magnetic compound.here are measurements of a Dali Rubicore 6. It shows drastically narrowing dispersion above 7k. BTW why do you find that our woofers are similar?

Having a raised border around the edges can affect the response, but it depends on the driver shape, directivity and frequency range used. (And of course the height and shape of border) The midrange may be the most likely to be affected in this case. However, there may also be a benefit if it reduces outer baffle edge diffraction.Not according to my findings. Perhaps you can elaborate why it should?

I wonder how much it'll be? I like the floating baffle look.
Then you have to diy it yourselve ;-)12-18k, “made in Denmark” is worth 5k at least.
I want to have custom built surround speakers based on all Purifi drivers and 1+4+8 looks around 8k for one pair.
Then you have to diy it yourselve ;-)
So a day's work for you to cover the cost of "made in Denmark" ;-)Actually I will rather charge 500 eur per hour for things I am really good at and let people that are much smarter than me build the speakers for me![]()

I think the real question will be: are the tweeters OEM only or not?I wonder how much it'll be? I like the floating baffle look.
