You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

When you get a horn that will work i will trade for a couple weeks!I don't think wide band drivers are the ideal way to do things but the most cost effective way to injoy good sound i would like to make another pair to crossover from 3k to 10k.some...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

Jorge, if you have 120hz horn with a 4" throat and 10" driver then Fane 8M would be a good candidate in my view. If I were you then I would try. The SG146LG is you had would be very interesting to try as well. Not to try it stupidly as most of Go...

[quote user="horny"] Those used to vintage gear might find it laughable…[/quote]
Well, do not be under impression that vintage drivers are an assurance of some kind of quality. They are not; in fact in most of the case the opposite is true. I always...

Very interesting. I appreciate that you have exposed more of your listening sensations - that give more objective information, letting to propose more accurately what might took place. In regard to what you say it might not be the “phase ...

It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE builds, but of the owner's design...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

[quote user="jessie.dazzle"]Have you ever tried the Community M4? I'd still like to try this driver.[/quote]Yes, I think we had a convesation about in the “The Macondo’s Upper Bass Channel: what is next? “ thread, I have linked it to current thread. ...

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...

Hm, this is what I am playing how: the new 18-cell and S3. I run it from a full time Milq and use it with no filter of any kid. Rony is right the depth effect is there, it is not even depth but rather multi-dimensionality. Indeed very pleasant feelin...

Anthony, it is not the subject of this thread but I am replying you since you raised a question. Is there are a lot of conspiracies about Tannoy vintage crossovers. They did many different versions and all of them well known. If somebody need I can h...

I’m glad you talk about geometry, but to respond to this I have to refer to other brands. I will only talk about facts and hope it’s not offending anybody.My basic point is: the flare rate has to be coherent right from the entrance of phase plugs. In...

[quote user="Romy the Cat"]I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you.

Of cause it shall be mentioned in the context of thin there that there is always the ALE Acoustic solution. The Japanese ALE Acoustic make two midbass drivers: P1260 and P160.

[quote user="be"]Both the Fane and the Goto where used as compression drivers, so there where no principal differences of use. [/quote]

Somebody "KCCT82" from Devil Audio site posted information about own installation.

TAD ET-703 compression driver <12k-20k> (107db 8 ohms)TAD TD-4002 compression driver on 400hz tractrix <1.9k-12k> (110db 16 ohms)GOTO...

[quote user="rdrysdale"]….as of now I'm convinced that a compression driver is the best way to go for fast, detailed and dynamic bass. The compression ratio needs to be just right, and the horn needs to be right, when these two are working together p...

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.

[quote user="Romy the Cat"]So, if the Ultimate MF Compression Driver is used from 1000-1500Hz then why shall it be able to play 500Hz? The answer is: he harmonic reserve – the driver that will be suited for 500Hz will have larger cone and softer sust...

Hello again, Romy.. let me see if I can clear some of this up....
first, you are indeed correct on your horn thoughts.. but some clarification is in order...
Ming Su is the importer of GOTO to the USA... Goto Japan only ships horns from flar...

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...

[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...

It is good that Cessaro come up with own driver. I wish they come with own driver a few years back. Use TADs for year and did not express criticisms to many TAD qualities was kind of “blind” and a bit devaluate the entire statement that they were try...

Thanks, El, an interesting driver indeed. It would be interesting to listen the thing though I have personally no use from that type of driver. Purely on the specs there are some moments that I would like to see different. The 250Hz resonance freque...

[quote user="rowuk"]Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the a...

YL 75000 has heavy phase plug indeed , rca style (see sketch) while 1250 ( I never had one) gets a fixed metal dome equivalent to spherical piece on 75000 and rca plugs without conical shape pointing the exit of throat. Ironi...
