 12th May 2014, 10:00 AM #1 LTD Co   Banned   Join Date: May 2014 Location: California Oris 150 horn? I'm looking for exact dimension of Oris 150 horn. I want to build them myself. if anyone has any information please let me know and receive the first pair for free as an appreciation.
 12th May 2014, 10:53 AM #2 CLS   diyAudio Member   Join Date: Jun 2005 Location: Taiwan You can figure out the dimensions by tractrix formula or hornresp. In hornresp, a tractix horn with 150Hz cutoff is: mouth: 4185 cm^2 (or 73 cm in diameter) throat: 250.62 cm^2 (or 17.86 cm in diameter) - for 8" Lowther or other 7~10" drivers length: 40.7 cm The Oris 150 has roundover at the mouth, so the overall diameter is strecthed a bit to 76 cm or so. Formula here: Tractrix - Wikipedia, the free encyclopedia ps. I don't need another pair. Thank you.

Thanks for the input
I have Tractrix calculator but Oris 150 is different. it's not a pure Tractrix. it's a bit different. I know the basic info about them but I want the ark curve

thanks anyway,

And, don't forget all the 'imperfections' on the big throat and the driver itself, which is the starting point of the whole thing. In addition, such big throat mid horn is not very effective above 1-2k Hz, effort (and obsession) on the minor detail of horn contour won't give you much reward.

I bought mine from Doppenberg in Holland about ten years ago but I never had a chance to finish the project I had in mind. My horns are still unused, they are painted in high gloss red. Please let me know if you are interested.

Now can you tell us what is the difference between a conventional tractrix and the Oris horn's curve?
