Hornresp

[grindstone]

If I'm tracking, he just wants a half-wave resonator wtih the slider -- no Vrc no Vtc just dbl-ended open pipe with the driver on the side (not inline). No, we can't do those 🙂 Er, at least we couldn't when I wanted to. I used the Akabak export and edited-in a "mirrored" end and another radiator. If you just do it in math like xrk does everything (positions as functions of L), you can manually "slide" and iterate driver positions. Er, if you just want to find the happy spot, it's half-way. As always, asymmetry and taper will vary results and be touchy beyond comprehension.

what did i create?

Dual or double chamber 8th order BR.

I guess this is a 600cm pipe with two open ends ? I had no idea we could model double open ended pipes .. kinda cool , like that flute in band camp 😝

345.6/6/2 is 28.8hz

How could I convert the Hornresp sim attached that represents the top image to the stubbed horn illustrated in the bottom image?

I'm trying to do so because it doesn't look like Hornresp allows for the simming of a lined or stuffed Vtc. However, if I swap the section S1S2 with Vtc, then I can include the impact of lining or stuffing that section.

How could I convert the Hornresp sim attached

As shown below (the results will be identical if no filling material and chamber resonances not masked):

In the u-frame open baffle simulation can baffle dimensions (width, height, sides' length) be entered ?
How ?
Thanks

Thanks David!

The U-frame baffle is modelled as a cylindrical segment with the driver at one end, and the other end open.

S1 = baffle width x height
L12 (Con) = side length or depth

The example below assumes baffle width = 25 cm, height = 20 cm and depth = 20 cm.

Perfect, thank you very much.

Hi there.

Im getting a run time error - 13 "type mismatch when using the Multiple entry horn simulation. Is it clear form my screen shots why this might be?

Im also having trouble moving back to the ND window after activating ME1.

Could someone explain in a very simple (click by click ) way how to navigate from completing my active me1 record to the ND window and set it to edit mode.

I have a feeling my error is based on this transitional step.

once I have the wizard i'll be all set to complete my sim

all the best

What Operating System are you using?

 

[boscotaylor]

Hi there,

My system is running Windows 11. The version is 24h2 (OS build 261004061)

Thanks David for this excellent program. lots of fun over the years!

Thanks for confirming that you are using Microsoft Windows - that eliminates one possible cause of the problem.

Everything works fine for me however, using the input data from the screen prints you posted.

Q1. Does the error occur when the Edit button is clicked on the Nd record, or afterwards when trying to open the Multiple Entry Horn Wizard?

Q2. Does the Nd record work okay if the ME1 record is not activated?

Q3. Would it be possible to export the ME1 and Nd records and post the files here as attachments, so that I can check to see if the contents are corrupted in any way?

After activating the ME1 record it should only be necessary to click either the Previous or Next button to move to the Nd record, click the Edit button and then select the Tools > Multiple Entry Horn Wizard menu commands.
