Yes, there is a Radian replacement diaphragm for original JBL phenol ones. It's a 4" voice coil, aluminium alloy dome with mylar suspension. Looks good on paper but I don't know if it is good. The retail is $210, usually goes on Ebay around $160.So y...

[quote user="mats"]Good start Dan!The JBL phenolic 2" driver is 2482.I would lower the crossover point as far as you dare, 300Hz or so.Now the 2226 will do what they are pretty good at.Later you will likely want to filter the 2445 around 2k.A 600Hz h...

ltsv38, it is an interesting solution for lower midrange horn. If I use something like this for Macondo ‘s fundamental channel (but of cause spherical) then I would flip the horn with driver up and run the neck longer to accommodate a slower, expone...

Roman,I don't think I've ever read your explanation why not 2482? We are all on a holy grail path to find a (somehow) available good compression driver that can go down to almost 200hz in domestic conditions and there are not many better candidates. ...

If you are still looking, there are a pair of vintage JBL 2482 Drivers with JBL 2328 horn throat adapters attached currently on Ebay. The guy says he also has another one he could sell as a single if you are still interested. http://cgi.ebay.com/VI...

The picture sure does looks like 2482 and it comes with Phenolic disphram (I have a pair though never used), but it's more like a mid-low driver. JBL's recommendation is 300~6k.http://www.jblpro.com/pub/obsolete/2482.pdfYoshi...

These are clearly JBL pots and back covers (which have been milled flat). The refinishing job is quite nice, but the origins are clear. Also, the phenolic diaphragm is clearly for the 2482/2485 (and looks like a JBL part), which has a slightly wider ...

Kris, I agree with you about the unobtainable 300Hz.Had really hoped for that, but so far no go with my set up:An old Oris-150 with a 4" throat wood adapter/cradle that John Sheerin made for me,with the 2482 playing out the back, so you see the entir...

Pierre, yes, I understand it. It kind or irrelevant what they destined for and yes, in domestic applications in context of low power we can use it lower. What I am saying is that as we do use it at extreme low range we deal with slightly overdamped d...

Romy,I have seen this a few times with JBL and Altec drivers. This phenomena occurs more often in Alnico magnets than any other type of magnet. When a magnet is recharged, it is blasted with a very strong magnetic field. There is really no way to “ha...

@Mats -- Thank you! This has already been the best sounding system I have built and designed, but hearing how good it sounds, lets me know how good it can be in the future. Thank you for the info on the JBL 2482. I've considered swapping the diaphrag...

I wanted to answer some questions posed by interested parties. These speakers are 8 ohm and were both manufactured on the same date in 1998.

My humble guess is that the titanium diaphragm won't ever give you the feeling you seek.JBL 2482 with its phenolic diaphragm may not be the quickest or most detailed, but has a truly wonderful tone that I never tire of....

Can I ask all of you who may have a valid alternative of the WE555 to a 4-way system so composed?High: super tweeterMedium-high: Iwata horn with JBL 2441 or similarMedium-low: WE15A horn with driver ...? (I have the JBL 2482 is ok for a WE15A?)Lo...

A kind chap from the Lansing Heritige forum has identified my new driver as a 2482. Interestingly those good radian people do an replacement aluminium diaphragm for this driver.What remains to be seen is how big the advantage of the original phenolic...

somehow i missed that moment in macondo development when you introduced S3 as a low mid driver so this came as a surprise to me - what i remember is that you didn't write so favourably of S3 back in 2004 due to its ceramic magnet. but it's good t...
