Anyone familiar with the Manger driver?

Wolf -- what's "hologram profile"

Hi Gregm,

the holoprofiles are a kind of plastic thing which have to be placed on the manger speaker itself. They costs around 400€ per pair.

Advertisment Manger: "Our latest development, the Manger Holoprofile, sets new standards in stereo reproduction. You can finally break free from the limitations of the stereo triangle with our patented sound deflector system."

Here is a link in german, but at least you get an idea and how they look like:

2: Select german
3: Click on "Produkte"
4 :Click on "Holoprofil"

Thanks, W.

Manger is fast driver and needs fast amplifier and wide bandwidth source.

I believe Mangers have been used in PA applications in Germany.
You should find out from your local dealer how Manger has gone about doing this.
