I will start a thread on the project and the listening tests when I get the drivers back and start on the project after the New Year. The Radian diaphragms don’t need this hole ,because the Mylar surround is perforated.
JBL / diaphragms – Forums
The speakers are in very good condition and the woofers are refoamed and measured with data sheet by a german professional: I once mounted a bad diaphragm on jbo of a and pushed down on the dome to see how close it is to the phase plug, and it is very close as it should be. I just cant find it anywhere. I posted the pics from an ebay auction here on another thread a few years ago, asking what they were.

JBL H-1 High Frequency Driver – Speaker Exchange
His are stamped I joked about it being a tuned port for the rear chamber. The differences are largely cosmetic.
Edited by coner – 30 August at JBL made a H with that phase plug. I wonder, did the early model ‘s have H drivers in them? If you want people to feel the bass then a reflex design is probably best as you get the most air movement per decibel from those.
Speak of the devil and the devil shows up! I didn’t know the Radian ‘s had holes in the surround!
All the JBL list says is that it is a 1″ titanium diaphragm used in bjl large number of their cabs Besides, the diaphragm is thinner than the and the surround is different too. There was a little space and he had problems to center the diaphragm exactly.
Didnt expect the crossover to be so low Ok, thank you Rudyi think you’re right. This page was generated in 0.
JBL 2416H 1 JBL HF Driver
The was last produced in and used a H-1 according to JBL service documentation. What the actual impedance is over the frequency range is another matter.
This weekend i will measure the DC of my friend Driver too. Other than the un-used holes for the non-used back cover, even JBL would not be able to tell the difference. I also own 4 H drivers, and it’s phase plug has radial slits. It appears they will, but are there any other smaller details for me to be aware of? So the Air can flow behind the diaphragms. Now it’s obvious I have too much time to waste at work on a Friday morning finally, the question to be asked: Perhaps it is for equalizing pressure, as you guessed.
Its not a problem going down to 4 ohms for the amp but I may just be putting to much into them Last edited by Rudy Kleimann; at As the pair of these are wired in parrallel on my latest test project I want to make sure I have it right Is there a audible difference?
