Great work and you could not have chosen a more difficult speaker to duplicate

I have heard the MBL speaker a couple of times , the last was more than 10 yrs ago , so I'm not sure of how it compares to there current stuff. What I do remember was that the sound was sweet, gentle and a bit 2 delicate and soft for my taste.

They also did required a ton of power and was always demonstrated with there monster size amplifiers ..

cheers ....

Unfortunately I have to change the coil on the coil capton fabric with aluminum skeleton.
Capton is not quite rigid, as seen in the measurements.

Did a online search for patents related to the radialstrahler but there seem to be none put up by MBL Akusticgerate GmbH for the technology behind the radialstrahler series of speakers. Anyone on the forum had better luck?

I have searched the European patent office database + worldwide search at the same location and MBL Akusticgerate GmbH has no patents.... Link: espacenet — Quick Search

Hope to see more information on this speaker from user areczek. I want to build this speaker!

From internet searching for about 5 minutes only - so I may not have a very good understanding of it - it is simply about making the air compress (or sound propagate, to put it another way) in an almost spherical way.

Instead of the usual forward and back, flat air compression from a conventional driver, these use that motion to in turn compress the "balls" which then compress the air around their spherical surface.

I bet if you could see the compression wave, it would be more toroidal than spherical.

So, for me, that begs the question is the significant thing about these speakers the 360' kind of "dipole" action giving the fantastic sound as opposed to any kind of revolutionary driver? To me, the drivers behave fairly conventionally in terms of speed of movement etc etc.

A simple idea - one of those that you wish you'd thought of yourself!

Has anyone, commercially or at home, ever tried a 360' electrostatic speaker?
