BlieSMa 7" midrange Domes

[Penelinfi]

I don't think I've ever seen dome midranges this big. Good with the sensitivity, IMD and nicer dispersion than large cone, but still with big peak to filter. Needs to be put inside a rear chamber with stuffing or you come up with some way to filter the cavity resonance for dipole use.

Interesting midrange driver from a technical point of view. But at a price of around 2100 Euro for a matched pair? There are other midrange drivers out there from Scan Speak, SB acoustics etc., which are available with excellent measurements for far less money.

It's been reported as "end of life" product in couple of shops I checked,why is that?

At SoundImports, you can find the acclaimed BlieSMa tweeters. BlieSMa built its reputation by building tweeter designs that are at the top of the driver design

IIRC Bliesma is shifting to a B2B model only.

Maybe I'm missing something but a midrange that breaks up at 1-6khz is not ideal. Impressive motor of course.
