Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

The exceptional 15-inchers would be two fitted in two categories: the bass 15-inchers and wide-range 15-inchers. It is imposable to think about the exceptional and wide -range 15-inchers and do not mention the 1946 -1973 production of the Tannoy Dual...

[quote user="Romy the Cat"]Sand damping it beautiful, it is well-recognized, but you do pay cost for it, in your case the cost is space. [/quote]I know that Romy… but without the massive amounts of sand, there are always some vibrations felt when I t...

Thanks for the tech info, Merlin; it helps a lot, especially combined with the preferred music revelation, up the thread.I agree that the OPT figures in to the sound, all right, for better or for worse, and there is no mistaking the OTL "clarity" by ...

Last week I have written an article: “Upperbass preoccupation and Vitavox S2 driver” where I ran over some my thoughts how the specific sonic virtues of Vitavox S2 driver allow to get an “interesting” upper bass from an upper bass channel, even thoug...

[quote user="guy sergeant"]If you use the plastic surround S2's from 500-5KHz won't you still have the bulge that concerned you at around 1.2K? I thought you suggested that the metal suspension units didn't have this bulge.Otherwise it seems a nice i...

Although all of it has no relation to digital crossovers but still:

[quote user="rdrysdale"]Our bass driver has a 12v field coil motor, it developes just over 20 kilogauss flux density using a low carbon steel pole piece. The exit diameter is 4 inches at the moment. The diaphragm is 6 inches in diameter and made of a...

Thinking about my Vitavox S2 “fundamentals channel” I can’t stop think about my hypostatic view about the horns. Year after year I was mucking what GOTO does when they introduces a horn for a couple octaves. Ironical now I am truing to do the same fo...

[quote user="Jorge"]I guess you cannot say you listened to a horn system if you dont have an upper bass horn. [/quote]Yes, I can very much concur with it. The upperbass and MF horns set the frame of the sound, sort of sonic skeleton upon which everyt...

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...

Get your Upper bass horn sounding properly first, this should be a lot of fun,
Play it by itself untill you get the perfect sound out of it
adjusting the back chamber volumen changes the sound a lot.
Why use a different driver form 2400hz? Do...

[quote user="Rewind"]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. [/quote] OK, but it is not how I feel about the service of injection...

[quote user="Romy the Cat"] 4" throat into 1x1m mouth…hmmm, you hardly
will be able to get from it 50Hz. Even if you go for ¼ size and 2 drivers then I think it is a bit too
small. Also, looking at the picture it looks like your horn open up too s...

[quote user="Romy the Cat"]Oh, God, what the measurement microphone does at the mouth
of the horn? Is it where you measure your responses? I hope not. Also, even over the bad sound of YouTube
video it is very clear at the example you provided us t...

Andrew you got to read the site, get into it, there is a lot of useful information regarding excactly the project you are going into, is there any difference if the threads are addressed to you or someone else? Most of them are Romys own learning ex...

Novigera, let's ignore any issues of sound quality first. A horn loads its drivers and increases efficiency only at certain frequencies. The frequencies that are more efficient are based on length, taper and size of the mouth. That means that it does...

...this interesting point has no practical answer. First of all in the case of Rakesh horn what N-Set proposed is not necessary. Those 115Hz Hasqiun-style horns that Rakesh emulates are well dumped with own mass and own ...

[quote user="Romy the Cat"]...to hear it from a person who advocates a single driver approach :-)[/quote]
Hahhaha, if
you call the combination of 4x23” + 4x15” + 12”+ 8” +2” a single driver
approach, then the people who really use single driver sp...

Here is an interesting setup. It is nowhere in Moscow Russia. I did not hear it but it does not mean that we can’t analyze what the authored was trying to accomplish.
It is 3-way installation. Bass looks like dual G...

I would like to suggest an alternative factor or explanation to your recent ULF/midbass findings.When you were chronicling the design and implementation of your midbass horns I was curious as to the effect of the very close placement of the two h...

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]

I changed the new flash at my site to “Ok, the midbass horn project is successfully over. Over 3 months, over 400 posts, over 180 pictures… all publicly available…” The project started physically on July 16, 2010, ended on October 28, 2010. The prepa...

There is a new company out there that makes horn-loaded acoustic system. I know a guy who is involved, I presume he is the owner or one of the owners, but I know very little about the design and the sound of the Sadurni Acoustics. So, let see wha...

[quote user="jessie.dazzle"]Is this because of the way you are driving them?When testing my one completed mid-bass horn (AK151 into 40Hz Exponential with 8" throat), and powering it from an amp that drives everything from upper bass to HF, the output...

To save people from researching the differences between Romy's and my systems, I'll note the principal differences here, ignoring our ongoing mid-bass projects, which will be different, but both are incomplete, so not yet in the picture.As concerns t...
