Default DDD bending wave driver

Anybody have experience with the German physics DDD bending wave 360 driver? Seems to be similar to the Manger, only that in addition to working down to 80 Hz, it'll also radiate at 360. Their homepage is full of self-hype and a few Japanese awards. Points for one of their finished speakers in German Stereoplay magazine are ok but not spectacular, especially if one considers the outrageous price (1500 Euros for a single driver, about 2500 Euros for the simplest DIY kit).

Heard them at a trade show. Big room, Lux Electronics. Based on that listening they seemed quite good, but the price is very high.

The one mounted on the ceiling was interesting.

Don't those things operate like a Walsh driver without a surrounding box?

Are they anything like the drivers used in the mbl radialstrahlers?

I would be concerned about the lifetime of the rubber strips that connect to the metal strips.

They are Walsh Drivers, with a lot of tweaking between then & now. They will just sell you the driver. You add you own enclosure (small) plus bass driver below 150 Hz.

Forgot to provide the link: http://www.german-physiks.de/index1.html

They will sell lots of finished speaker as well as a kit for the smallest one (Windspiel). And you can get the driver without anything else.

Mark, being familiar with the DDD's, what rubber strips do you refer to?

Jan,

if you are familiar with the DDDs, could you describe your impression?

Thanks,

Eric

Eric,

I don't own them, but at one time had the privelege to listen to them at the designers' place. This is maybe 8 or 10 years ago and I must say we discussed mostly the technical aspects of the driver. For me this was a cut or two above *normal* driver technology.
That said, what I remember from the listening sessions was the absense of any coloration I could detect, plus the incredible resolving power. I remember to literally hear the singer on a CD moving to and from the mike a couple of inches during the performance, something I don't remember having heard since. Being omnidirectional drivers, some care must be taken not to place them too close to the back (and side) walls to avoid too many reflections.


Cheers, Jan Didden
