"That is "subjectivist" nonsense. State your technical and scientific reason for 1) and 2)."
Well the technical reason for 1 is totally obvious because the same panels reproduce the whole frequency range so by definition the same material is used. This means that the coloration would be the same over all frequency ranges would it not?
Point 2 is also obvious what is there to state? It is a full-range single driver speaker so there where a simple RC filter is used to narrow the radiating pattern with increasing frequency to thus retain a wide even dispersion but there are no abrupt transitions. Got it?
"Hint: Your ES's are anything but "coherent" as acoustically large line sources. Got any polar data Chemist?"
How do you figure? Got any data to the contrary?? Seems like you are trying to "slow play" me (to steal a poker phrase. Don't be coy, if you got something to prove then prove it. It is not easy to find data on 20 year old speakers you know but I can direct you to information about Acoustat Spectras and you can see for yourself. I can only assume that you are referring to beaming? But Spectras correct for that electrically so there is some phase shift but it is minimal compared to a speaker with steep filters that garbble the hell out of the signal like yours do.
It is sadly ironic that you have dipole speakers and yet can't understand the benefit of having the whole range covered by a single type of driver, especially when issues like beaming have been addressed.
"Got any polar data Chemist?"
Coherence has more to do with impulse response than polar data and in that regard my speakers are far more coherent than your garbbled up mess for speakers. I have in-room FR data and the speakers are +-2db from 200Hz to 12Khz or so with no correction. As this measurement is in-room then I consider this a reasonable proxy for a polar response as off-axis is included in such a measurement.
Another thing it is silly for you to try to use my educational background in a derrogatory manner. It clearly demonstrates your ignorance that says you believe a person can be an expert at only one thing, when nothing can be further from the truth. If you must use a title I would prefer Dr. Chemist. Or better Dr. Analytical Scientist because I spent more time researching and developing analytical hardware than just about anything else during my Ph.D studies. If you wish to see the fruit of my labors then please visit the TSI inc. website (www.tsi.com) and look at the mass spectrometer in the products section. Click on the brochure and look at the references at the bottom and there you will find BD Morrical (that's me) in several references. I know a lot about engineering, mechanical and electrical as well as systems integration. This knowledge carries over just fine into audio, I assure you.
