[quote user="cv"]This is but one reason why I'm asking Martin Seddon to make me a pair of 160Hz horns...[/quote]Another problem….
Chris, be carefully with those large 160Hz horn and S2. The guys who make then have no instruments to center the mounti...

[quote user="decoud"]Regarding centering: how about making the bolt holes on the ring oversize relative the bolt diameter so that there is some play in the position until the nuts are tightened? Obviously, one would have to have oversize spacers too....

The surface of my fiberglass horns is quite rough. The mould was sprayed from a distance with some water based paint - so it all landed in fine globules. Maybe this is too fine a rough texture though. I like the idea of thick artists oil paint…

decoud ,
If you wish you might use my method that I “invented” or my Fundamental Chanel. My MF Chanel horn uses a sophisticated harness with centering functionality but in but Fundamental Chanel uses a very simple “extended ring” method. It us chip...

And here is an image showing the driver in the mounting plate (still unable to upload the images; can only include them as attachments. Also, I have to do this one image per post).
Threading on the S2 does not go all the way to the tip of the driv...

Wow, it took 3 hours to take it apart. As I always told those vintage driver made horrible. The do sound Ok but precession-wise and technology wise they were very pure. They really were the low teach devised made for popping up the sound pressure but...

Yesterday I spoke with a guy at a Russian audio forum who reported that he played with addressing many problems of compression driver by pumping ferrofluid in the gap. I am not a big fun of ferrofluiding generally and in case of compression drivers i...

Nice work; bravo Mike! With regard to improvements to the S2: Apparently Romy's prayer, one of them anyway, has been heard and would seem to have been answered; a diaphragm-centering guide has at last been added. As for the rest (other improveme...

Another particle of a good Horn Propaganda. It was published in Sound Practices in 1994 and written by Joe Roberts. I disagree with quite many of the author’s statements but his strategic view that the majority of the horns and the horn installations...

From Email that I got today:
“….. I see that you are considering trying the metal diaphragm again in your S2s. I am using the metal diaphram for the moment (it is all that i have), but have the terrible ringing problem, especially on female vocals. ...

[quote user="jessie.dazzle"] What really surprised me was how good everything sounded with no filter on the upper-bass horns, and all drivers connected to the same (8 Ohm) tap; sure I'm getting too much mid-range from the upper-bass horn, but its...

I made today some interesting experiment and for the first time during my “fundamentals channel saga” I get some stimulating and very result. I find a way to mount the “low frequencied S2 driver” on the speaker’s axe way above the Macondo’s tweeter. ...

Jessie,
I was about to replay to your post and suddenly John Hasquin posted his reply that said exactly what I meant to say. In fact he has much more credential to assess the validity of you attempts then me as he actually build the horns. In additi...

Very good point - I will direct Martin's attention to this. Visually, it looks like he did an excellent job on the 340 Hz horns, and the 160Hz horns will be rolled off at 1k anyway but nonetheless, will see what he reckons. Actually, no need - I just...

Ah, your horn this way does not have own axis and the axis of the back plate become actually the axis of the horn? This way you get rid the ugliest element of co-axising – the integration of the axis of horn and the back plate. Very-very cool indeed!...

For centering :
The thickness of the ring that clamps the "bug screens" is around 3mm; in other words, there is a very short (+-3mm deep) "horn" in front of the screen. This allows one to center the driver using a metal (or hard material) tube or...
