JBL 2416 DRIVER

His are stamped Perhaps it is for equalizing pressure, as you guessed. Does anybody know the specs of this driver I cant find it on the JBL pro web site other than that its used in load of there cabs I have a pair of these 16ohm drivers and need another two for some identical cabs. So how do I check its resistance if its not clearly listed? Extra Tabs by vBulletin Hispano. Hi, i’m a german newbie here and since last week i own a very nice pair of JBL There was nothing on the inside of the diaphragm.

JBL H-1 High Frequency Driver – Speaker Exchange

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. I just bought a pair of Radian for use in JBL drivers. There was nothing on the inside of the diaphragm. Would also prevent the woofer and cabinet from modulating the diaphragm like it was doing in your case.

I wonder, did the early model ‘s have H drivers in them?

I want an alternative close match in case I cant find any. This weekend i will measure the DC of my friend Driver too. I too have wondered about that. Radians are well-made alternatives The Radian diaphragms hold the promise of a smoother sound quality with the inherently better resonance-damping qualities of aluminum as compared to Ti, and the Mylar surrounds on the Radian avoids aluminum surrounds’ inherent weakness of ubl from high-output flexing which led to cracking and diaphragm failure – the reason JBL switched from Al to Ti as a diaphragm material in the ’70’s.

Ok, then JBL must have matched the crossovers for these early Versions here is a pic from my crossover: Ok, thank you Rudyi think you’re right. That being said, I suppose it is possible that the model progression could be as follows: I have never seen ferrofluid in any JBL drivers, including the ones I have that the diaphragms are labelled H Didnt expect the crossover jbk be so low My came from a studio-basement only stored for custom replacing-requirement,so they are like NOS!

Perhaps it is for equalizing pressure, as you guessed. Perhaps the early production models used a H before the -1 variant. 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.

I recall noticing the different DCR on my diaphragm compared to Now i read about the replacing Radian drivers with aluminium diaphragm and Mylar surrounding. Does anybody know the specs of this driver I cant find it on the JBL pro web site other than that its used in load of there cabs I have a pair of these 16ohm drivers and need another two for some 246 cabs.

What the actual impedance is over the 216 range is another matter. The speakers are in very good condition and the woofers are refoamed and measured with data sheet by a german professional: London and Birm Status: Hi, today i swapped back to my original titanium D8R When I mounted the bad diaphragm to the H and pushed on it, the space between the diaphragm and phase plug was MUCH greater, perhaps times as much as on the definitely not right.
