This is what I have in mind.

S1 and S2 will have the same value
S3 and S4 will have the same value
Make L12 the depth of the chamber
Make L23 .01
Make L34 the port/line length

Thanks. That looks good.

I know that I once saw a DIY done like this for sofa side but I can't seem to find it now. Anyone seen such lately?

Hornresp Update 4600-180705

Hi Everyone,

CHANGE 1

The loudspeaker and filter wizard group delay chart limit guidelines are now removed by pressing the Esc key rather than by double-clicking on the Y-axis vertical scale. This makes removal of chart guidelines and markers consistent across the program.

CHANGE 2

Double-clicking on the Cir or Fta label in edit mode now specifies a closed mouth horn. Attached are three examples of closed mouth horn systems.

Kind regards,

David

David, could you add "Acoustic path length between outputs" parameter to "Loudspeaker wizard" mode? Thank you.

Thanks Mark! I take it that we can't control the rotation of our phone pics.

I haven't found a way to do it. But a little diggin goes a long way.
Great to see David get the honor he deserves.

It's easy to do, the problem is remembering to do it. You need to watch for and control the orientation of the camera while taking the picture. Open the camera app, rotate the phone to landscape, and then rotate downward to take the photo. Watch the little camera icon in the display to make sure it's in the orientation you want. If you sync the photo's to a Windows 10 machine you can right click on a photo and the rotate option is in the popup menu.

Hi Orion33,

It's already there 🙂.

Display the Path slider by selecting the Chamber input option.
Enable the Path slider by selecting the Power and Combined output options.

Kind regards,

David

Hi BP1Fanatic and Mark,

Many thanks for posting the Live Sound International / ProSoundWeb information. Chris Grimshaw advised me some time ago that he was considering producing an article, or possibly even a series of articles, on loudspeaker design and simulation. It is nice to see that his proposed project has come to fruition.

Kind regards,

David

Thank you, David. I did not guess how to activate it 🙄

The pic is fine in my phone. The site changed the orientation when I uploaded the pic from my phone.
