This is probably the reason I can listen to EV Patrician IV in relatively small space and close to the speaker without much of fatigue.  The other factor must be that it's 4- way design with narrow band-pass for each horn. EV T25 2" phenolic compression driver (alnico) is still cheap on Ebay although JamminJersey list it for $400 a pair, seems like it's gaining popularity. I have infamous JBL2470 1" big magnet alnico with phenolic diaphragm and was thinking about fundamental channel design around phenolic driver >500Hz -1000Hz counting on dia ability to play lower into LF without breakdown. The thing is I don't know if there would be any advantage over cone midbass streching up to 1000Hz without buying big expensive 250-300Hz horn .

You are very much might be correct. Electro-voice and Klipsh used phenolic driver quite aggressively and some of their their speakers had some send of softness and non aggressiveness. I certainly not willing to admit that all phenolic are soft but it would be just a general tendency that metal cones are more … “momentary”.  Another example is Cogent that use phenolic – thy too soft and do not go transiently where I would like them to go. In case of Cogent the softened is also come for the electromagnet that makes then overly polite…

I think a cool direction to go might be to use a naked fibers or soaked cloth, I never tried but I would it I were in driver making business, The best metal cones do fine as they damped with soft suspension, with loading and in some cases with proper coating (like JBL uses aquaplass). I also do not feel that the driver’s resonances is necessarily are bad things, the main question to me is what kind of resonances they are. In the end if one know the driver well and the driver has right characteristics then it is always possible to deal with the specific driver imperfections.

Using horn drivers is in a way like dressing an ugly woman. The woman know what she need to do with herself in order to hide what is not necessary to expose and what to highlight as the most tradable commodity. The drivers are the same… They are all upon our will…
