Topic: what is the so-called "healy pattern"

ok, i will think about it.  might have to bring ramsden into it, if he can mod gear, im sure he can help me out.

evidently you have not seen me try to build anything physical.  a bond ladder i can build, a portfolio i can construct.... but using saws, levels, is just a disaster waiting to happen.

Have you read the argument against laddering based on investment delay ?  Has anyone quantified it in percentages ?

Oh, wait, that's work....sorry, man. My bad.

The Jecklin disk can be made by ambitious grade-schoolers.
Perhaps you have kids in the family ?

clearly you have never met JBK.

so you could probably still do it, just with more spacing between the caps...if healy is supposed to be 4 or 5 inches separation or so (the width of your head), make the LD's 7 or 8...would that work?

See, I don't think you can run the Healy Method with LD's. It is not really the Healy Method anymore, because you have two diaphragms on the LD capsule. When LD's are run in omni, technically it doesn't matter if they are running 90º to the sound source or aiming directly at it because with two diaphragm's, there is no real "aiming" of an LD when in omni. It's non-directional in that pattern.

When using the SD's though, you eliminate this problem when running them at 90º to the sound source, back to back aiming away from each other due to the lack of the rear diaphragm. This creates the spacing and time difference.

This is just my thoughts on all of this...

interesting Jason.... I have no real idea...

how about healy with a jecklin disc ?  wouldn't that solve the problem for LD folks ?  

even with SD mics (akgs, oktavas), i always noticed a "smushed" middle of the stereo image when running healy method, something that I thaought would be solved by a disc.
