Hi Marcel,
Thank you for the reply.
Kindest regards,

Thank you for the reply.
I had never had a good experience with importing *.stl files, although following the help (Solidworks).I think there's no reason why you couldn't simply trace the contours of the STLs, as most CAD products probably have an STL import function.
That may be a good option, but this is even more unrealistic, because I would need to be able to edit the imported *.stl file, and as noted above, I had not had much luck with the imports.My recommendation would be to start with a suitable existing adapter and only modify the mounting, preserving the air path, if possible.
Kindest regards,
M
Hi MarcelNone of this is conical. The whole adapter, connecting the driver and the main waveguide body (which is a truncated R-OSSE), is in fact a "free hand" curve (a Bezier cubic). That's the convenient way of doing it.
would you mind to explain it
You can see the inner shapes of the adapters here: https://at-horns.eu/gen2.htmlHi Marcel

Those are Bezier splines, simple as that. Of course always optimized via BEM, including the whole waveguide.
There's not a straight cone anywhere (anymore). As a result, the acoustic impedances seem more "polished", probably a good sign.
The "ROSSO adapter", right from the printers
(two different printers used, 0.6mm nozzle for the adapter, 0.25mm for the ring) -
I still only need to check it fits as it should, some adjustment still may be needed.

BTW, these are not supposed to be glued together. The ring should be inserted into a driver firmly (with a bit of a removable glue?) and then the rest of the adapter tightened to the driver with screws, over the ring (again, with some thin bonding/filling layer between the two).
So you dont have R-OSSE parameters for ATH A250G2?You can see the inner shapes of the adapters here: https://at-horns.eu/gen2.html

The common part (the main body) in combination with the standard 1.4" adapter make one pure R-OSSE profile - that's also how the basic performance is set. All the other adapters are then created differently - by connecting a spline to the common part, which gives a lot of flexibility. For those, there's no single R-OSSE curve.

Thank you Marcel for answer.
I thought that it is simple as you explained, just wanted to be sure.
I assume that we can make a drawing in ABEC, add it to ATH designed horn and simulate all together.
I never did it before, but remember that you couple of time advise similar.
Am I right?

BTW, the effective throat diameter this way is 26.9 mm.
Hello happy builders. I'm testing Chinese DSP car amp that has 6 or 8 channels 150W with PEQ/GEQ and crossover/delay - total price shipped 269$ with measurement mic, BT and remote. I took my STH280 monitor and corrected passive crossover. Next I will remove passive and reprogramm again. You can store as many "scenes" (configs) you like. Phone app is nice. Optical input and BT. Thorugh USB you can use autotune but it has only 2 target curves and it doesn't correct as good as manual way.
Black is with HF lift made of 3x GEQ with Q=0.5

It's a good question. How long (roughly) is the exit conical section in that driver? The angle is specified as 21° conical, which is relatively wide and brings some possibilities. As a first step, I can easily simulate an adapter including the original exit section to see what happens and what it needs.for Faital HF10AK, what extension do you recommend?
Hi Marcel
I saw all your adapters on your web page and shaping them is clear. That can be whatever somebody want and think is better.
I know those are noob questions for some people here, but what is not clear is procedure. Which software to use to draw connectors, how to connect them to R-OSSE horn and how to import them and analyze in ABEC and VACS?
If explanation is to long and you are to busy do not bother. You gave us more than enough so far.

How do one remove the bug screen form the CD?

You mean how would people design their own adapters to my waveguides, like the A520G2?Which software to use to draw connectors, how to connect them to R-OSSE horn and how to import them and analyze in ABEC and VACS?
Of course I do everything with Ath (it's still expanding), and a little bit of Desmos, but that hasn't been published. But I can imagine adding the original Ath script into the STL package(s), so that it would be more convenient for people to design different adapters using a BEM simulation of the whole, as you may already be used to. This would also show how to do it, so anyone could proceed with their own. I only stopped giving all completely for free, as the experience was not only positive.
Is this what there would be an interest in doing?
