Well I don't know a better place to post it, and I do not feel it is enough information to justify a new topic.IIRC the ALE 160 driver is reported here (goodsoundclub) as having a 4" throat diameter but I found out it may be indeed 5" but with a "SUP...

The picture shows a JBL 2446. It shows where one attaches a horn. The exit hole in the center of the driver is about 2 inches deep and 2 inches in diameter. Is that hole part of the throat chamber or does it count towards the first 2 inches of ...

I'd guess that the only difference compared to the modern version of the K-Horn is a throat plate size of 6"x13" like in EV Georgian and use of ticker 3/4" plywood for enclosure. Myself, I settled on Klipschorn as a midbass solution 40hz to 100-150...

be careful here as mouth size is defined not by what you input, so much as the acoustic space and performance you want. The throat size can be fiddled with if you're careful but there's not much one can do to shrink the mouth. On a 'bass' horn you ca...

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...

its still expensive, but birch-plywood is not that much cheaper. its around 30-40 €/sqm. the only experience i have with a carbon-foam composite is from making a skateboard for my gf´s son. looks very good, but whats more important, ab...

KeithGoto's recommendation is to buy the throat piece of a S150 horn(It comes in 2 pieces).Then have the horn cut to the exact diameter of your tractrix and have a flange welded on.They made a special adapter for my mid horn,but recommended the above...

Ming,
I was thinking about this SG146LD4 driver again. They say: 106 dB/ 20 - 500 Hz, 19,000. Well, let look at this a little bit further as I feel that might be very interesting driver.
I admit I never heard about this driver. All that I know abo...

Hello,This is my first post to this site, which I have been absorbing for over a year.A horn project that I have been considering would include either a 1 inch or 1.5 inch throat compression driver into a Tractrix profile horn of which I have not yet...

But efficient (in terms of space usage) and radical.put woofers in the sides of flare of your attic horns, sort of like Danley Synergy horn, not near the throat but towards the mouth area, using the attic as the infinite baffle.But will the pressuriz...

I wish I could stop the US government from selling AK47s in any corner shop in the US. If you give a monkey a gun, most probably he will shoot himself. If you give a monkey an AK47, well that is different. He will take anything he wants and few thi...

This is terrific information Ulf. Thank you very much. I won't start builing until early december but will post the project here.
Plan to form my horns from microcrystaline wax first, so i can experiment with throat termination. I have a background...

Romy - forget pulling the throat protectors out... just blast them out with a cheesy 1812 and have the canon shots modulate the lights... Solves the issue of the ceremonial initiation too in secular fashion...Seriously though, I can't wait to hear (v...

So they will need some "teaching".The most difficult students are often the most promising.Are you able to say whether the problem is due to the horn position relative to the room, or to throat diameter relative to the driver diameter?jd*...

I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, and no crossover ...

Great answer, thanks, I get it, although the embedded logic is hardly limited to horns.But I still want to know whether - and if so, then how - people are dealing with throat sizes and horn profiles during development, since no one mentions it spec...

[quote user="cv"]Regarding what effects the larger horn will have: my gut feeling is that the larger air mass will provide more damping anyway. It may be that there's an optimal bug screen "density" that varies with the air loading?[/quote]This is ve...

Johan, I understand what you are saying. This is kind of James’ barn thread and if you do not mind can you share with him one thing, I think that many others, including me, would be interested to learn the answer to this question: What did you gain g...

Well on the upside, I suppose midbass woofer cost is reduced by Half..Seriously though, I'm curious what shape throat and woofer (or driver) Jeffrey used in the ~50Hz bass/midbass horns.Neil...

It looks promising JD. What ratio of diaphragm area to throat area did you arrive at (for the large horn) & how did you choose it?...
|
|
I am not sure what you are asking. If you willing to get 400Hz horn into 1” tractrix then it might not be any controversy about the horn’s length, it is already given and the folks from lab.de will know it and will do the right length. If they have m...

just got it that you meant the diameters,of course its around 65%. i always calculated the throat-size with the area....i really would like to get a second pair of s2´s but i think right now it would be difficult even if i had the money;-(((if i go f...

[quote user="Wojtek"]I use regular Lowther DX4 (ENABLED) . I don't think the 250-400 is stellar and I'm still waiting for the extension to try small throat for lower midrange (2,75") (B&C 8P21E driver) for 200-1000Hz .[/quote]Look...

Romy,
I can't find a/the post(s) where you describe the advantages of using a 4 inch throat. Stereo-lab makes both 4 and 8 inch throat 140Hz horns but I don't think they could make an 8 to 4 inch adapter...
Also, would it be advisable to have t...

I picked recently a pair of S3 drivers. Not that I need them but it was good deal – perhaps someone in UK have demolished an old movie theater and a large school of S3 drivers with original diaphragms hit the maket recently. Also, I always meant to t...

The first and the bigger thing that I like about them is that Anima is trying to use the vertical-horizontal configuration where the bell of the vertical horn serves as frame for horizontal channels. I love this idea and had a number of my own th...
