Explanitory

The old Kharma filosophy "Reality as a Reference" requires no-compromise products, including only no-compromise components. This means that when silver-gold wires sound best; we use them. Also it means that if they sound even better after a time-temperature controled process whereby the structure of the material is altered, we will use this process. It means that if we cannot find binding-posts that don't live up to our standards, we will devlop them ourselves.

When a diamond cone for a tweeter has got the best specs of all materials on earth and really nothing sounds better: we use them. The so called underhung system turned out to be a way of creating a way higher efficiency. And so we combined this with these diamond cones.
High Pressure Laminate because of the weigth and other properties is best fit for creating a loudspeaker cabinet we don't mind using it specialy not in combination with several types of massive woods.

But; all this not for it's own sake, but only to serve the purpose of re-creating reality, right in your own home.
