Years ago, the two different systems in which I heard RCA 1428s - in a fairly big warehouse and crammed into a basement listening room - used giant RCA multi-cell horns in combination with giant Ubangi bass bins, passive crossovers and vintage WE or ...

Hi,Finally, I have time to build some horn speakers and learn what is it, bought JBL 2440 drivers and before my frame will by finish (next week) and horns will arrive I want to renovate those drivers. My question is:Can I take off that "grainy" topc...

Probably the s4600 . They are replaced by the s4700, around 20k $ if those are the ones. There are very few models of the ultra high-end jbl here in france, but they are very well respected. I have never heard....

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...

Interesting. The manufacturer published specs I had observed for the 2206H are different from what I remembered, for one obvious reason: I was remembering the specs for a 15" driver, and not the JBL 2206H. No matter, since manufactu...

I also am selling my JBL 2490 mid-range drivers and perhaps a collection of my original Aura 1808 drivers. The 2490 drivers are new and Auras are some old and some new. I just do not see myself to develop any inspiration to use them......
|
|
Paul,at least from my moronic standpoint, using a couple of closed boxes with wide band drivers (I have some JBL LE-8T2 without the aluminum domes) in a L-R/R-L connection, should give me the power to widen the stereo basis. Adjustable level could ma...

Hi all!I have build few horn projects. And i can't figure out how i can get rid off back chamber nasty sound (resonances) (300-500hz region).Horn is 150Hz conical with JBL 2020H driver in 14L cilinder....

If you look around the site, there isn't much DIY effort to just build "anything" here.You could probably get exactly what you are looking for by googling "Econowave" or SEOS though.On the other hand, you could just build what you drew and then tell ...

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on thi...

2011 will be a busy audio year for me. I will have a nice large space 28 feet x 20 feet x 11 feet which I am free to modify for audio. The walls are 150 years old irregular stone the floor is cement and the ceiling is composed of structural...

If you are happy and enjoy the sound, that is all that matters!Do you have pics of your system?What drivers are you using? JBL 2441? Tweeters?What version of UBH do you have?I have a very close friend with a wonderful Edgarhorn system, I understand t...
|
|
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...

[quote user="jweiss"] It was good to finally meet you at CES at the Cogent Room. I guess that you really found Steve and Rich's drivers pretty interesting (you initially wanted to buy a pair of the midrange drivers, remember?) [/quote]
Hi, Jonathan....
|
|
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="Markus"]Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that.
I would love to use ho...

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

[quote user="zako"]I did not like the two slit configuration of the phase plug..but the five to one compression ratio produced low distortion,,,but i was not impressed with its bandwidth,,,JBL also used a eight inch speaker assembled to a special...

Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...

Romy,I took your advice and now have a single 2440 driver. At least i THINK its a 2440. On opening it i find that it has a phenolic diaphragm! Have I been sold something else? I was not aware that there were ever any phenolics for the 2440 family. Wa...

The room is beautiful, and I love the tree stump "rack" with the amps, it is clearly a work in progress, but they already put in the "Western Electric" badges on! It talks a lot about their priorities I guess!They have what seems to be a midrange ...

some months ago. It was posted at AA about a year ago or so. I keep the "solutions" if someone interested wants to know his scoring and how much of a "fundamentalist" or "overtonist" is.The only interesting thing about it is how being one or the othe...

Romy, thanks for your prompt response. I find your response a bit appalling since I seriously hope I can get away by achieving a similar sound by not paying the full price. What did click about the Olympian? Might be easier to do comparison. Say ...

Well, I'm still waiting for 2m 40Hz horn, 200Hz and 270Hz LeCleach. But can't wait to try something!But I'm very eager to experiment with drivers I have, so this is what I got today!If someone has expirience in judging recorded sound, welcome to comm...

Romy, hiDid you get the chance to listen ? I did listen for some time Kevins development pair in 2008 and they were superb (Using very large subs). I have a pair, in fact the first pair of tone scouts Kevin made. Interesting no one talks that much ab...

[quote user="martinshorn"]The bass horn for the ak151 is housing a rear chamber slightly open, giving the injector channel - that creates a lot charme, flavor and „heart“ but also 3 dimensional projection. [/quote]I need to say that that very muc...

The other possibility is that the MF issues can be the problem with the JBL 2441 rather than the amplifier, and it would behoove me to explore the Vitavox driver.

[quote user="cv"] That said, I do have is a single 160Hz/1.5" finally up and running on a compression driver, and it's a different world - stunning. Actually the results are exactly as JJ described. [/quote] The JJ, is it Jeffrey Jackson? I have no i...
