So how do I check its resistance if its not clearly listed? Well someday we will have Beryllium replacements I have only seen pictures or heard about the H phase plug with the holes.
Now it’s obvious I have too much time to waste at work on a Friday morning finally, the question to be asked: I haven’t actually seen my pair of Radians ‘s yet, as they are with a fellow LHS member who received, installed, and ran F. His are stamped I joked about it being a tuned port for the rear chamber. The differences are largely cosmetic. It is virtually identical to the Restructured post for clarity.
The was last produced in and used a H-1 according to JBL service documentation. JBL made a H with that phase plug. This page was generated in 0. I also own 4 H drivers, and it’s phase plug has radial slits. I wonder, did the early model ‘s have H drivers in them? Both have the same original titanium D8R fitted.

JBL 2416H-1 High Frequency Driver
Phaseplug with holes ,like mine. I didn’t know the Radian ‘s had holes in the surround! Perhaps the early production models used a H 4216 the -1 variant.
I will jb a thread on the project and the listening tests when I get the drivers back and start on the project after the New Year. Thinking about it, I need to clarify that the drivers I saw on ebay a few years ago were listed as H, but as we all know, the driver itself isn’t marked -only the diaphragm. Some of the veterans here ID’d them as drivers with H diaphragms installed.
There was nothing on the inside of the diaphragm. He screwed open his with same result.

Buy a pair of blown orthread off the adaptor, remove the rubber tire, remove the cast back cover with the push-button terminals. We noticed this before,because the Horn produced a “farting” sound by playing Bass-Sinus signals. It fits perfectly,so i don’t worry about. In two days he will receive his Radians,then i will check his Drivers again 4216 done my own tests on the 216 “Chinese” aftermarket diaphragms, The curve and distortion end up all over the place.

I too have wondered about that. Well do you want ‘s or something else??
