Interesting, but as I learn they didn't test dipoles. Damn. Research must go on.

Hi, I didnt try Scilab. In theory both Octave and Scilab are Matlab compatible so I think there should be no big problems as I used only basic functions and nothing Octave specific comes to my mind.

If you are using Scilab, yes please, share with us how it goes if you run the script.

This thread sounds like "I know that dipoles sound best, therefor that technique which supports this conclusion provides the correct metric." That's not science. I know of no data that supports the assumption.
Everybody has his own perception.
To me this thread sounds like "MANY find dipoles sound most natural. Let us find the science /metric to support this". Many theories in science started with an astute subjective observation made just by the sensory organs of humans...that was later supported by the physics and math. Newton "saw" an apple falling. We "hear" a dipole as the better sounding.

I would be very interested in the dipole vs cardioid comparison using Elias's methods by JohnK.

Ok, I will give it a try and post back.

Agreed, as long as the researcher leaves open the possibility that his initial assumption/hypothesis is incorrect - i.e. maybe dipoles are not the best sounding LF source. I, for one, do not believe that they are. I don't believe that anything else is any better either. I believe that it all depends on how the room and subs are setup and that the source type is a distant second in importance.

The source type is just a tool to reach a certain goal. Unfortunately in consumer audio land the tool somehow became the goal.

In all fairness, it is hard to separate the two (goal/tool) in your statement markus. Since acoustic reproduction is taste driven, the goal determines the source type.

Yes, that's true. Things become problematic when the tool characteristics become the basis for supposedly generic metrics used to evaluate performance. The performance metrics have to come from subjective studies, like the one that you asked about - a very good start.

It's very hard sometimes.

If the bottom line is "What sounds good to me.", then what is this thread all about?
