Newbie question, first time pulling apart compression drivers Top end is similar the Ti’s. Install a new pair of 2146. I’ve done my own tests on the JBL “Chinese” aftermarket diaphragms, The curve and distortion end ubl all over the place. It appears they will, but are there any other smaller details for me to be aware of?
I joked about it being a tuned port for the rear chamber. All these seem like measures to cut back on production costs more than anything else Good question Speak of the devil?
Its jb a problem going down to 4 ohms for the amp but I may just be putting to much into them I didn’t know the Radian ‘s had holes in the surround! D8R diaphragms use aluminum voice coil wire.
The noise has gone.
I suppose that the LF driver could pressure up the cabinet high enough and long enough at very low frequencies to modulate the HF diaphragm through that vent hole. Ok, thank you Rudyi think you’re right.

Too bad the won’t fit any of the older structures. All 7 of my H drivers have the radial slit phase plugs. Extra Tabs by vBulletin Hispano. Buy a pair of blown orthread off the adaptor, remove the rubber tire, remove the cast back cover with the push-button terminals. There was a little space and he had problems to center the diaphragm exactly. Ok there is no need for a replace ,but some people said the Radians are more “refined” sounding and have 246 distortion because of lower mass.
Phaseplug with holes ,like mine.

Hi, i’m a german newbie here and since last week jbbl own a very nice pair of JBL This is only my educated guess and not to be construed as fact. Originally Posted by grumpy. There was nothing on the inside of the diaphragm. I only heard the plugs with slots are cheeper to produce. Now it’s obvious I have jjbl much time to waste at work on a Friday morning finally, the question to be asked: 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.
I have only jvl pictures or heard about the H jbo plug with the holes. Now as for cleaning out the internals, I’ll save that question for next week! 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.
Ok, then JBL must have matched the crossovers for these early Versions here is a pic from my crossover: I just cant find it anywhere.

That farting sound you heard was probably the diaphragm crashing into the phase plug. Now i read about the replacing Radian drivers with aluminium diaphragm and Mylar surrounding.
We noticed this before,because the Horn produced a “farting” sound by playing Bass-Sinus signals. I frequently recommend the alumnium replacements from Radian.
Notengewirr, are you satisfied with the refoam Happy new year to all, Guido. The DC resistance of an 8 ohm H or H1 is 3. I have never seen ferrofluid in any JBL drivers, including the ones I have that the diaphragms are labelled H By timc in forum General Audio Discussion.
These farting sounds comes out of the Horn-Front. Possibly an aftermarket diaphragm was installed. It fits perfectly,so i don’t worry about. Only a few weeks ago,my best friend bought another pair of But I know all 7 drivers have the phase plug with annular slits. As far as I know, that looks like a phase plug.
I saw a lot of coming out of cabinets. 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 Ti as a diaphragm material in the ’70’s.
Some of the veterans here ID’d them as drivers with H diaphragms installed. A bit less top end than the later drivers with slit phase plug. I once mounted a bad diaphragm on top of a and pushed down on the dome to see how close it is to the phase plug, and it is very jjbl as it should be.
