His are stamped All the JBL list says is that it is a 1″ titanium diaphragm used in a large number of their cabs This page was generated in 0. Hi, today i swapped back to my original titanium D8R Possibly an aftermarket diaphragm was installed. Those “aftermarket” diaphragms that claim to fit, and drivers, are correct only in that they don’t hit the phase plug, but that is it.
A bit less top end than the later drivers with slit phase plug.
The Radian diaphragms don’t need this hole ,because the Mylar surround is perforated.

I have only seen pictures or heard about the H phase plug with the holes. The DC resistance of an 8 ohm H or H1 is 3. There is no difference in performance. 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. Well do you want ‘s or something else??

I can’t imagine an aftermarket diaphragm sounding anywhere near right in a -but they “fit”. What the actual impedance is over the frequency range is another matter. My came from a studio-basement only stored for custom replacing-requirement,so they are like NOS! Install a new pair of diaphragms. Ok, then JBL must have matched the crossovers for these early Versions here is a pic from my crossover: Forum Permissions You cannot post new topics in this forum You cannot reply to topics in this forum You cannot delete your posts in this forum You cannot edit your posts in this forum You cannot create polls in this forum You cannot vote in polls in this forum.

This is only my educated guess and not to be construed as fact.
Last edited 2146 Rudy Kleimann; at They really sound smoother than jgl Ti’s. I can’t speak for the dates or original diaphragms on my drivers, as all of mine were bought used. Does it have a breather hole in it? Last edited by notengewirr; at From my newbie eye, I see the has a more substantial magnet, and the diaphragm assembly is located in a recess I too have wondered about that.

It fits perfectly,so i don’t worry about. I wonder, did the early model ‘s have H drivers in them? I posted the pics from an ebay auction here on another thread a few years ago, asking what they were. The differences are largely cosmetic.
JBL 2416 / 2418 diaphragms
I frequently recommend the alumnium replacements from Radian. Only a few weeks ago,my best friend bought another pair of However, the dome of the phase plug is not as high as the previous models, and the diaphragm is built kbl match- it will not fit on H drivers because the phase plug of the sits too high.
One of his diaphragms doesn’t fit exactly on the driver-plate. So the Air can flow behind the diaphragms.
