Thanks Bjørn, now I understand :-).

Kind regards,

The spreadsheet doesn't have any calculation of the basic areas, it just takes in distance, radius and area. So I guess you could take the exported distance and radius values from Hornresp, and put them into the spreadsheet to get the radial horn dimensions.

Noticed they lacked but you can take the data either from Hornresp or use the original equations(as I do for Exp, Kw(S) or Tx. Haven´t tried to export the text-files from Hornresp. LC must be taken from Hornresp.

Just for fun, this an (not so typical) example that I still haven´t finished: An Altec 511 Exp rebuilt for taking a 2" driver with help of a JBL 2328 adapter.

Hy everyone. I am having a hard time fiddling out some correct Driver paramaters of "typical" PA-High Frequency drivers in order to simulate some horns from 1-20kHz. Simply measuring the TSP gives strange results...
Does anyone have some reliable real-world driver-parameters as a starting point for one of "the usual" 1", 1.4" or 1.5" drivers (B&C, BMS, 18S... not really important, it´s more an academic issue - we want give the CNC something "meaningful" to do and thought of starting building hornflares...)

Hello,

For a design not intended to be adapted to a special loudspeaker, you can set Eg = 0.

Doing this you'll have a constant velocity source replacing the loudspeaker.
No more need to introduce T&S parameters for the driver...

Best regards from Paris, France

Hi everybody!
Have downloaded hornresp zip file, but I'm unsure something is wrong.
Zip have GOM player file I can not initiate 'cause of missing codec - but can not find codec on the link provided. Saiz the file is corrupted.

Lars (Revintage) has give me notepad, but seems to be I'm unable to paste it into hornresp.
Would someone be so kind to tell me what I am doing wrong way?

Thank's!

I am not sure if I understand correctly, but it seems you are trying to open a ZIP File with a media player?
Take Winrar (or 7Zip or Winzip or something else that´s capable of handling a ZIP File).

You need no codec. Codecs belong to the video/audio domain and are used to play music or films oder videoclips...

Understand why you think so - my silly english , but not.
When I unzip hornresp there is also GOM file among hornrespons files. That file can not open.
I can open hornrespons and seems to me like it is working. But I can not (or don't know how!) paste notepad that i got into hornresp.

You have GOM player as default videoplayer and files with extension .dat setted to be opened with this soft. This .dat file is not to be managed outside of hornresp and is not a video data, is the database of your projects.
To use the notepad file save it into Import folder in the honrnresp directory. Run hornresp and use the option File -> Import -> Hornresp Record.
