The Multifaceted Random Dipoles – what the hell is it?

Well, this is what Eugenie’s uses, perhaps without realizing it. I do not know how Eugenie came to it. I presume that he was buying over the years the drivers on eBay and now he decided instead of trashing them to put them in use. Still, behind of what Eugenie did there is some interesting educational rational.

I call this eject “Multifaceted Random Dipoles” – which is purely pulled out of my ass name. A few years back I was visited a local friend of mine who just bought a bid Wilson. Walking across his room while his playback was playing I suddenly got flabbergasted. The sound in one specific point on the side of the room was nothing short of stunning, if not stunning but positively- different.  Upon further investigation I figured out that it for a first direct reflection from the left Wilson and a large glass window on the side of the room created combined with direct Wilson sound some kind of new “balanced” soundfield. 

Later on I did pick up the same effect a few times mode. It was always a specific balance of direct and first short-reflected sound at very specific mix. I was trying to mimic the effect using multiple drivers in free air configuration, turning the drivers and modifying bandwidth and volume. It was very difficult to get right configuration but sometimes I was able to catch “special” effect. The culmination of everything was when I was driving w divers and let them freely spin. I mean: to hand the drivers in the long wire, to twist the wire up and then let to wire to untwist, spinning the drivers with different speed. Using 4 wide band drivers and turning the volume and speed the effect was very interesting. I called it the “Multifaceted Random Dipoles” at that time and put the observation to back burners.

A couple years back ad guy from Switzerland contacted me and told about his idea of using directional reflectors that focus reflected sound back to ears. It was interesting and I supplemented his idea with a few rotatable reflecting reflectors. Eventually it has no practical use and end up to be at the same back burner.

Reading about Eugenie payback with 200 accidental drivers my old feeling about the “Multifaceted Random Dipoles” came back to me. I do feel that  partially the effect that  Eugenie get has the similar nature that I had with my above-described experiments.
