Hi All,This is Ming Su and I am the US distributor for GOTO and J.C. Verdier. I thought that I will share with you about my new midbass horn. As you know by now, Jeffrey Jackson from http://experiencemusic.net/ help me on this project.&nb...

Ok, I will share with you some ideas that I have in my head how to deal with horn decay asymmetry. They are in a way the further development of the Haralanov’s idea of acoustic diode – the brilliant concept from my point of view.
Before I will...

Active sound cancellation has been used widely in industry as ANC (Active Noise Control)They work best and functional in narrow band bass FRQ. To make it short it is not practical in your case... Bass FRQ have enough power to vibrate horn mouth and c...

Hi Keith,Is there any chance of sharing the measurements? I agree with the your comment regarding the sound of them. Although in saying that, I have managed to only listen to a few other different compression drivers so far. Is there somewhere I...

[quote user="jessie.dazzle"] Regarding the Mid-Bass : If these guys are using the main block as a Mid-Bass horn (as Romy's illustration suggests), then the story is getting interesting, and the plot is definitely thickening... It would however seem i...

Re-reading, I realise you stated your preference for a sealed bass array only in relation to Dreyer's bass horn, not to bass horns in general....

About horn body resonance: I used to doubt the need for mass in horns; after all, how much energy can a flimsy paper cone generate? Still, I went ahead and followed the advice of others when building mine, making them very strong and heavy. With ...

[quote user="Romy the Cat"]audiofilofine, you need to form a question in a format that would indicate you do the your do some homework. To bulb or even to design 20Hz horn is complex task and it usually made to the specifics of the given circumstance...

I would like to expose what my intentions are what I was tiling above about Goto 555 or a similar 200Hz driver. My S2 does not stress the bottom of my 183Hz horn. My multi-cell is expositional and those types of horns do pick honk very aggressively ...

Since I got my stable and good quality electricity back I recalibrated my bass horn. Again, I set it up with very precisely and absolutely without any measurements, juts by ear, to sound exactly how I want it to sound. This is in a way my crown jewel...

I am still here still trying to work it out. Read your mid bass horns article again. Learned a bit more. You right about open baffle I once foolishly sold everything I owned to buy a pair of km30. They never sounded good until one day...

Martinshorn , that for feedback, as I always preach:
the bad result during audio show does not mean anything, only good results
count. You see, there are zillion reason why during the show the sound might be
horrible. The inadequacy of the people ...

Midbass from horn in
small room can be hugely benefited if it bounces but to make the
assembly of horns visually pleasant, time aligned and functional at the
same time is a big question. I do like the notion of Midbass fires t...

Here is the list of the thing to do with Vitavox S2 in order to use it in 4-ways installations. The S2 must not be used in 2, 3 ways systems. It possible to do with S2 whatever you wish but pretty much any other way to utilize them produces some very...

[quote user="noviygera"]
For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

[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...

Yes, this English pace did not give a lot of new information. I know nothing about the AudioTekne Company. I like that they wrote about their bass driver but I do not know how much truth and the actual results behind it. I do think that they wor...

[quote user="skushino"] I think you are saying the effects of my room may be dominating any problems with the Edgarhorn bass, or at least I can't know since I don't have any objective data. Is this correct?
Maybe you're right. But here is wh...

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]

[quote user="homebuilder"]I am new to this interesting site, and am hopeful of getting some assistance with a project. I have purchased a set of TAD 1201 mid-bass drivers to begin a 4-way active system for critical home listening. (in a d...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

I think what I gained from the basshorns were 1. "Speed"or lack of momentum.Specifically deep notes on piano.The sensation of that leftmost keys with the initial impact then followed by the resonance from the instrument as separate entities.I...

A guy read my site and sent me a series of emails complaining that it is too difficult to found Imbedded positioning for his new bass horn as it is too big and too balky. Moving the large and heavy thighs and measuring them is the hard. I agree, but ...

Ok... Assuming the lack of time alignment is compensated for via a DSP:
There are likely large chunks of the frequency spectrum that go un addressed, and equally large chunks that are mall-addressed.
I would say that there are two main ranges ...

Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...
