Hi David,
I'm seeing some odd behavior in going between the Wizard and the plot of the resulting saved design, looks like they are not using the same math?

Hi Mark,
There will be yet another minor update in the next few days 🙂.
Kind regards,

Hi Dan,
Could you please post a specific example (with screenprints if possible), to enable me to replicate your results and to then investigate the problem further. Thanks.
Kind regards,

Hi Dan,
Many thanks for the example - the problem was confined to negative flare parabolic horn segments only. The bug has now been fixed - Product Number 2910-120902 refers.
The latest release also includes a change to the schematic diagram horn data export functionality. Previously the width of a rectangular cross-section could only be specified indirectly by entering the height (see attachment 1). Now either the height or width dimension can be entered directly (see attachment 2) .
Kind regards,
David

David,
I appreciate all your hard work in this product.
Obviously your an audio/computer nut!
Keep it going.
Since you give it away what would be an apropriate donation?

That'll do, but if you are going to have the horn on the floor you can use a flat bottom.
Happy SketchUping 😉
Cool, I suppose as long as the expansion is kept the same, it won't affect the response much, especially with a bass-horn.
You could think of the floor as a mirror of your horn. And speaking of response; depending on what your "requirements" are you might want to have a look at the off axis response. From the SPL screen do a [ctrl]+r.
Hi Daniel,
You are correct in your thinking.
Starting with S1 = 49, S2 = 2500 and L12(Exp) = 60 , I get a slightly different result to yours, but nothing to worry about.
Length...Height...Width
0...........70........70
100........67.......142
200........85.......213
300........123.....285
400........189.....357
500........303.....428
600........500.....500

Hi Etocynned,
Thanks for the feedback - knowing that Hornresp is proving to be useful and that my efforts are valued, is all the reward I need 🙂.
Kind regards,
David
I want to use this cabinet to match speaker i have.
I want guidance for hornresp input.
I have done but i think i need some guidance specially for ATC.
Please tell me if my hornresp inputs are correct or not?
So i need master's( David McBean) guidance if possible.

ATC looks good, but VTC appears to have an error... VTC should represent the volume of the cone and the cutout in the baffle, looks like an extra 0 in there.
Thanks Dan,
I calculated the area marked as Vtc.
The calculation is as under
42.07 width till horn starts
10.6 height
57.4 depth of the box.
so it calculated as 42.07 x 10.6 x 57.4 = 25597 + added speaker volume 4403.
So i rounded as 30000.
The triangle volume i adjusted towards round cutout of plywood .
Pl. correct me.

Probably best to define it as a segment to enable Hornresp to more accurately do it's job IMO
The throat chamber is a segment that calculates it's length via the ATC and volume you provide, but as I stated above a more accurately defined model is...
