I have never seen ferrofluid in any JBL drivers, including the ones I have that the diaphragms are labelled H Possibly an aftermarket diaphragm was installed. The was last produced in and used a H-1 according to JBL service documentation. I just bought a pair of Radian for use in JBL drivers. Install a new pair of diaphragms.

Ok, thank you Rudyi think you’re right. He screwed open his with same result. Besides, the diaphragm is thinner than the and the surround is different too.
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 work-hardening from high-output flexing which led to cracking and diaphragm failure – the reason JBL switched from Al to Jjbl as a diaphragm material in the ’70’s.
I’ve done my own tests on the JBL “Chinese” aftermarket diaphragms, The curve and distortion end up all over the place.
Install a new pair of diaphragms. I posted the pics from an ebay auction here on another thread a few years ago, asking what they were. Speak of the devil and the devil shows up! Now i read nbl the replacing Radian drivers with aluminium diaphragm and Mylar surrounding.

Perhaps the early production models used a H before the -1 variant.

Last edited by notengewirr; at Newbie question, first time pulling apart compression drivers I also own 4 H drivers, jb it’s phase plug has radial slits.
Perhaps it is for equalizing pressure, as you guessed. Phaseplug with holes ,like mine.

By timc in forum General Audio Discussion. 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. I can’t imagine an aftermarket diaphragm sounding anywhere near right in a -but they “fit”.
All these seem like measures to cut back on production costs more than anything else His are stamped I just cant find it anywhere. This page was generated in 0. As far as I know, that looks like a phase plug. Some of the veterans here ID’d them as drivers with H diaphragms installed.

I want an alternative close match in case I cant find any. All 7 of my H drivers have the radial slit phase plugs. I will start a thread on the project and the listening tests when Jjbl get the drivers back and start on the project after the New Year. All times are GMT Ok, then JBL must have matched the crossovers for these early Versions here is a pic from my crossover:
