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...

Romy---A pal uses JBL 3115s, speakers for small picture theaters that use a similar horn-loaded cones in a narrow range, from 250 or 300hz up to 1600hz.They sound pretty good, better than any high-end type speakers I've heard.Keep in mind though...

the sad truth was the space, the finite funds, and the available bms pucks! the sad truth also, i suppose,the lack of available, and sensitive horn users to bounce off of!i could probably see what your dislike of the bms stems from-- i tried to...

Hey Rom etal.I'm entering into unknown and difficult to intuit territory for me.I aquired a pair of very large constant dirrectivity horns EV hr9040 a, a little while ago and i now have a pair of jbl 2420's to power em. I haven't put them to gether, ...

Ok, I have found a “perfect” configuration for MF driver for my MiniMe: it is linear. I am sure that Silbatone folks and Trojan Condoms will sue me for copyright infringement but I think I will survive. It is sad that such a good dive is such a stupi...

[quote user="op.9"]Anyhow, what are the 2" comp drivers that ARE any good and are available comercially? I didnt go with any JBLs because I had a very bad time with the 2427 1" version, could never get any music out of it. [/quote]
I would be surpri...

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...

Sure, it is fully colored in JBL self-glorifying propaganda and their drivers from the last 20 years do not sound good but it is interesting to read that their objectives are remarkably similar to what I was trying to accomplish by my “Fundamentals C...

I did not see in your post any “sad truth about BMS”I would stick in the JBL 2440. It is relatively inexpensive. Has practically the same performance as the hipped JBL 375 and all together a good performer. It’s diaphragms are wildly available and it...

[quote user="Merlin"] Indeed the linearity of the Berning in comparison with the Lamm is quite remarkable, and indeed could be disconcerting to an inexperienced listener brought up on large increases on 2nd harmonic at the bottom end. [/quote]

Hi Romy,in another thread you recommended the JBL LE8 as a good driver for the 200-1,000 Hz region. Any specific version of that driver? It has been produced in different variants over a rather long time....

What I can say after audition of 2-way system with GPA 288 in 350hz horn and JBL 2453 in 550hz horn is that I like the sound without GPA 288.1-way JBL 2453 sounds terrific and 288 can't match that level.So, driver for 1200hz down is under considerati...

A six year ago or so when I played with different compression drivers I bought a pair of Dukane 5A540 and at that time I was not able to find any information about them. Nowadays I was pointed out that an eBay sealer “ bayleafs” actions a pair of Duk...

A few months ago a reader of my site contacted me and informed about that he found a very interesting driver, that his is using and he is very excited about it. The driver is JBL 2490.

Dominic:Welcome to the army of the "Great White Horn". I have been using these beasts for almost thrity years.The flange on these horns is designed for use with a 1.4" or 1.5" driver. The JBL 2420 is a 1" 3 bolt "JBL pattern" driver.Adapters are avai...

A few things I would like to say in context of Pham’s playback.
I will leave his infatuation with turntables alone – man like to collect turntables and he within his constitutional right to do whatever makes him happy. The problem that I see ...

I am quite fascinated with the result that I might get from MiniME and at the same time I am defensive with the direction it takes. Anyhow, here is how it stands…
The decision to go for MF driver was I think right one. Even the 70-20RX tweeter has s...

I think guessing what the hell they did with tweeters would make since if whatever they did sound right. Since Living Voice’s is not the company that has a lot of exposure in US I do not think I will ever hear those speakers. Even if they have US rep...

Hi,I keep for many years a set of speakers, JBL 2225h, JBL 2105h and JBL 2403h and I'd like to build a reflex compact speaker with a good low response (see the picture 1:10).

[quote user="el`Ol"]Romy, are you going to verify the decision of using fragile vintage drivers?E.g. by trying JBL midbass drivers?They would be closer to the design philosophy of the Fane Studio 8M.http://www.jblpro.com/components/maxout.htm#2020H[/...
