Thanks for the great program.

I wonder if it is possible to add High Pass Filter.
It would be usefull to control cone displacement in the design.

you could use Akabak for that, model in Hornresp, export an Akabak script, and then modify the script to include whatever filtering you like

Hi FlipC,

There has been a change of plan :-). From the next release of Hornresp it will be possible to temporarily store and recall up to four sets of Loudspeaker Wizard slider control settings.

The next release may be a few weeks away.

Kind regards,

David

David,

I LOVE the changes to the newest version, hornresp keeps getting better and better...

I do have a question, though:

I have modeled a single-segment, conical horn for 80-400Hz, and asked hornresp to give me directivity data, which looks very good.

How does hornresp simulate the directivity data? Does it assume a horn with a square or round mouth and throat?

My main concern is how the angles of the opposite horn walls in a conical horn affect directivity vertically vs horizontally....will I get what I model if I deviate from a perfectly square cross-sectioned horn path and mouth?

Thanks,

JSS

That's good Henkjan.
Thanks

I'll download Akabak and try it.

Best Regards

Has anyone requested the ability to enter mms, or reverse calculate mmd from mms? That particular spec is rarely published. And although I don't have a big problem with it it would be nice to be able to enter Cms in m/newton as it would be easier to read Click the image to open in full size.

I finally got some drivers measured for a line array project and I'm interested in a rear loaded enclosure like this:

How do I go about modeling this in HR? My drivers are all on 6.5" centers.

just enter the specifications for one of the drivers and under the Tools menu goto driver arrangemant and enter the configuration of your drivers and then model the horn segments as they are.

That by itself won't accurately model a line array, especially in a TL, etc, so about the best one can do in HR is to locate the line at wherever driver #5 is and hopefully the different line loading of each driver will average out 'close enough' to the one huge driver in the sim.

Anyone know if AkAbak can accurately sim this?

Hi Neo Dan and GM

What Hornresp does is add all the piston diameter from all the drivers into one. It will give you a green and a red circle for front and back of the same integrated piston. So I guess this works well for computational purposes but not so well for real life multi-driver situations.

I know that it can be done in AkaBak for sure. That is one evil powerful program. I know how to manipulate scripts generated through Hornresp but to go hole hog and do a multi driver model is beyond what I know currently. I have never spent the required time to really work through AkaBak. I'm getting lazy I know. But some guy named David McBean keeps making his program more powerful.

Mark
