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).
- 40 Hz - 1000/1200 Hz: JBL 2225h in vented box

If you ask me the compression drivers is like the jbl 2420/2470 design only with an other back chamber. And the low freq driver really makes me think of an old alnico driver of jbl 2220A http://www.lansingheritage.org/images/jbl/specs/pro-comp/2420/p...

It looks like JBL Jumped into the beryllium wagon with their new DD66000. It is $60K it is sexy look but frankly speaking I do not see anything stimulating/interesting in them beside a nice industrial design.
Here is also a link that “try” ...

I heard the Array 1400 at a show: https://www.neomax.ro/produs.php?id=P:5737-S:336It has the aluminum diaphragm rather than beryllium.The demo music sounded very nice. Effortless and beautiful.The midrange tended to spit and shout a bit though, like ...

A visitor of my site pointed out that the guys at AudioHeritage site have heard this new DD66000 speaker.

Romy,Since you have had experience with this particular driver, I wondered about your opinion of the sound. In my system I have the Edgarhorn Titans which use the JBL 2441 as the midrange horn driver. While I am generally quite happy with...

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...

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, ...

I never heard Everests and I hardly feel that I ever will hear them in a reasonable installation as the people who would use Everests most likely will be the people of “different type”. Still, I wonder if the Everests are the JBL’s 21st century glori...

[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]

Op, I clearly have no idea as I never have seen/heard about the 2440 with phenolic diaphragm. Who know perhaps they did it. The phenolic diaphragms were the invention in late 60-70s and a remedy against the nastiness of the first SS amplificatio...

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 have found the T90A to be reasonably in-offensive with JBL 2435 Neo/Be compression drivers.
I use them with relatively small caps, currently 0,3uF.
The effect is a welcoming of a higher frequency palette that to my ears does
not seem incongruous...

Yes, Jonathan,
I have seen this resemblance with JBL in the shape of the back plate but it does not mean anything. The curved back magnetic path make a lot of sense, so he might adopt it from JBL. There is nothing wrong with it.
I do not k...

[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....

Marchand doe crossovers not EQ and his crossovers are not so good sonically BTW, but I do not like even the idea of active crossovers anyhow. It is obvious that 2105/LE5 is not so simple driver to begin with but searching for “straighter” driver is e...

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...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

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...

Today LeCleach 550hz arrived together with another round horn - Jabo KH-53 (350hz).I've measured 3 drivers in 550hz horn: GPA 288, JBL 2453 and JBL D2430K D2.JBL 2453 really impressed me. This is definitely best driver I ever had!Tone is perfect and ...
