In two days he will receive his Radians,then i will check his Drivers again 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.
Considering that your ‘s and your friends’?
I just bought a pair of Radian for use in JBL drivers.

Ok there is no need for a replace ,but some people said the Radians are more “refined” sounding and have less distortion because of lower mass. Now as for cleaning out the internals, I’ll save that question for next week!

This is only my educated guess and jbp to be construed as fact. That farting sound you heard was probably the diaphragm crashing into the phase plug.
I joked about it being a tuned port for the rear chamber. Its not a problem going down to 4 ohms for the amp but I may just be putting to much into them Other than the un-used holes for the non-used back cover, even JBL would not be able to tell the difference. Results 1 to 15 of I frequently recommend the alumnium replacements from Radian. The Radian diaphragms don’t need this hole ,because the Mylar surround is perforated.
All 7 of my H drivers have the radial slit phase 2146. Edited by coner – 30 August at Is there a audible difference?
Would also prevent the woofer and cabinet from modulating the diaphragm like it was doing in your case. From my newbie eye, I see the has a more substantial magnet, and the diaphragm assembly is located in a recess I’ve been “donated” a bunch of bits from some MR and MR series boxes, and hope ibl make use of the comps.
Radians are well-made alternatives The Radian diaphragms hold the promise of a smoother sound quality with 216 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. The Radian diaphragm F. Both have the 4216 original titanium D8R fitted.

Perhaps it is for equalizing pressure, as you guessed.
I want an alternative close match in case I cant find any.

I saw a lot of coming out of cabinets. There is no difference in performance. Too bad the won’t fit any of the older structures. Notengewirr, are you satisfied with the refoam Happy new year to all, Guido.
JBL Questions : JBL H vs. RAdian
I will start a thread on the project and the listening tests when I get 2461 drivers back and start on the project after the New Year. None are working right now: That being said, I suppose it is possible that the model progression could be as follows: Last Jump to page: Speak of the devil and the devil shows up!
By timc in forum General Audio Discussion. London and Birm Status: He screwed open his with same result. I too have wondered about that. As far as I know, that looks like a phase plug. I have never seen ubl in any JBL drivers, including the ones I have that the diaphragms are labelled H 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 close as it should be. I just cant find it anywhere.
