Hi everyone,It is quite ironic that the day I hear from Fane telling me that the Fane 8Ms are finally ready, I should receive this update from my horn maker maestro. Russ Collinson of Layers of Beauty. Russ, if you ever read this here, please take a ...

Give yourself time and let your unconscious work on it; you might have overlooked a cause originating in the electronics.

Paul,
I have been working with trumpets since 1966 and horn speakers since 1975. I have built both and am pretty familiar with what they are, the similarities and the differences.If I had to pick THE major sin when thinking about all of the horns th...

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...

Last couple month when I rebooted my DAW it has difficult time to start up; it looks like motherboard is going and bias sometime during boot does not see hardware. Usually with 30 min and 10-60 automatic recursive attempts the machine boots and t...

Ah, you were asking about the tunning of the uperbass horn?
That is very simple. You need to make the primary resonance to hit exactly at
the horn’s mouth rate. So, it is it 110Hz horn then make the primary impedance
to peak at 110Hz, there are ma...

Thanks guys, I have contacted Peter and the JBLGuy, let see what it would fish. I would need to find the Vitavox Mike from UK, but all his formal contact do not works - it looks he closed down his old shop. If somebody knows his new email/phone t...

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. Let pretend that I went for exponential midbass profi...
|

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

This is terrific information Ulf. Thank you very much. I won't start builing until early december but will post the project here.

[quote user="CO"] I dont need flat to 20K but dropping after 10K necesetates a tweeter. [/quote]
And there is nothing wrong with it. No one 500Hz driver that said is doing to 20K in reality does it. In fact if a driver goes to 20K then the place for...

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...
|
|
Yes, but if you could make it broadband enough, it might function
effectively as a filter. IE, remove a broad notch from 300 to the mass
rolloff of the horn. Just thinking aloud. What about a front
compression chamber? That would seemingly be the ...

[quote user="noviygera"]I am very curious what "properly made" means when perusing the tonal attributes of LF. What properties or specifications other than driver diameter do you evaluate when perusing a better tone?[/quote]

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

With that Moscow guy it is not the question of his reliability but his sanity. I hope you understand
that response he gets is rather a measuring of his horn then measuring his
driver. He unfortunately neither intellectually (audio-wise) not psychol...

Luc,
I am not ‘lucfm’ and I hope he will reply to you but I would like to pass some of my observation that you might find useful.
In my past when I discovered Fane Studio 8M I went over a number of 5-8 inches. At that time I used AG’s Trio upperb...

Paul is correct ; you could make the vertical member from one thick hollow pole or tube and be done... this is by far the most economical route.
But since we like that curve in your latest design... (this could become a very powerful sculpture) :
