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.
But the woofer tech were I think they are almost the same.
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.
