Finding Rms rating??
Im not sure where to find or calculate the Rms field, mechanical resistance.
Could someone explain how to calculate it?
Also is there a table somewhere that lists the different names that some parameters are named. I vaguely remember that there were at least two parameters that different manufacturers use different names for.
Cheers

Hornresp will calculate it for you. Double click the Rms input box and a wizard will help you, allowing you to enter Fa and Qms instead of Rms and Hornresp will sort out the rest.
Most of the input boxes have wizards to help you and there's always handy info about the input box at the bottom of the Hornresp window if you hover your mouse over the box.
Alternatively, double-click on the Sd input box in Edit mode to enter all the driver parameters in the one operation, using Thiele-Small values.

Hi freddi,
In edit mode, with the Ctrl key pressed, double-click on the Nd label to step through the ME1, ME2, BP6, BP8, ABC driver arrangement options. Alternatively, select the Tools > Driver Arrangement menu and choose Aperiodic Bi-Chamber ABC from the drop down Arrangement list.
It's all in the Hornresp Help file - simply use the File > Find menu (in the Help file) to search for ABC.
Many thanks for this feedback. The second and fourth order active filters appear to be working okay in the filter tool charts themselves, but not in the main charts. I will investigate.
Kind regards,
David

I should have also mentioned that another way to specify an ABC system is simply to create a new record using the Input Wizard tool, located under the Help menu.

Hi bfmv,
That's an easy one to answer - sorry, it's not going to happen

Feature requests...
1. Change the frequency graph horizontal scale options to 10-20KHz, 10-2KHz, and 1-200Hz. The 1-2kHz option IMO isn't all that useful for analyzing bass horns.
2. In Loudspeaker Wizard, allow the user to change the horizontal axis on the frequency response graph by double-clicking on or below the horizontal axis.
3. Include "cone volume" as one of the storable driver parameters, and add it to Vtc in Hornresp's calculations. This will allow various drivers to be swapped in to a particular horn alignment without having to adjust Vtc every time to reflect the change in cone volume.

Hi Brian,
Changing the existing 1 - 2000 Hz and 10 - 20000 Hz frequency range options to those requested would be a massive exercise. It has implications all across the program. It's not going to happen.
Similarly, changing the frequency range from within the Loudspeaker Wizard would cause all sorts of problems, particularly when trying to compare results generated using different scales. It is difficult enough now. It's not going to happen.
Sorry, this one misses out also. You are just going to have to learn to live with adjusting Vtc manually.
If you are saving drivers to the driver database you could perhaps include the cone volume in the driver description, for ready reference.
Kind regards,
David

The best you can probably hope for with this is to use Akabak instead of Hornresp (or use the Export to Akabak feature in Hornresp). Akabak uses a script anyway, so all you need to do is write a script (small program) to change the Akabak script into something that Matlab will accept as an input. Or vice versa if you are using Matlab for calculations and importing a Matlab script into Hornresp.

Hi Everyone,
BUG FIX
When simulating a direct radiator in a closed-box enclosure with the 'resonances not masked' option selected, the fundamental resonance frequency marker line in the Loudspeaker Wizard was not being shown in the correct position (see Attachment 1).
This has now been fixed (see Attachment 2).
Kind regards,
David
