North D28-06S

[Jonasz]

Have anyone used or seen any measurements of this tweeter? Sure looks interesting to me with generous xmax 1 mm p-p, faraday sleeve and high sensitivity. They come in matched pairs for $159.

According to the informative pdf below it's made to be crossed down to 1,5khz.

I was going to ask the same question a few days ago. I just wondered if anyone had ever tested one of these?

I've got a pair, and it's scheduled for the great tweeter shoot out coming up.

The motor system is quite similar to the RS28a. The dome, obviously, isn't.

Jon,

will you throw in an oldie but goody like the D25AG35 (which I imagine you still have around) in the shootout for a that was then and this is now type reference? Looking forward to it no matter what ;x( .

Cheers,

AJ

Ya know, I never used that Vifa, though I'm familiar with it. Similar drivers I have are early MB Quart Titanium dome tweeters with diffusers, both dual and single magnet ones; I may even have some left built to the Avalon spec without a diffuser and with a different faceplate.

The test lineup I have right now includes


Hales Transcendence tweeter (made by Vifa, with a Faraday shielded motor)
Focal TC120dx2
MB dual magnet titanium tweeter
Millenium Excel
RS28a
H1212 Seas
H1283 Seas
NorthCreek D28
Seas 27TDFC (forgot the H number)
Modified LPG 26T
Scanspeak D2904-6000

I hope to get a set of Accuton C13 in a couple of weeks, also.

There may be something else I'm forgetting. I don't have any Seas H400, which was the "cheap" tweeter I used to use in the 90s (the MB titanium being the "expensive" one).
