How is your website coming along? I can't see much of it yet.

The best of the waveguides so far are on there. I'm going to put some wavelet plots up when I get a chance.

BTW I also have a couple designs for the Bleisma T25B on tap.

Do you have to remove the grill, or does that remain fixed in place? I'm very curious about these drivers.

Yes grill removed. It's pretty easy to do

A beryllium dome without a grille is not a great idea in terms of safety if you ask me. The beryllium dome tends to break if you touch it, and the stuff seems to be toxic. Maybe you could integrate a grille or similar protection like with the SB beryllium domes into the waveguide?

Imgur just shows a black screen. Any other way to show & share your findings here?

The images are visible to me on Firefox and on Chrome Android. Imgur might be blocked by a plugin in your browser.



I don't know why, but when I try to post the images here directly they can't be loaded or something. I don't know why my pictures don't show directly... Could it be relatied with my permissions?

Did you try to embed the pictures in the text? That does not work well for many users here. Just attach the images using the "paperclip" icon in the toolbar.

Linking to external graphics is not a great idea, because the links may (will) change at some point, or the files may disappear, and then the thread breaks because the information is not accessible anymore.

Alright, I think I got it!


Once again. Simulation using Vituixcad:
- Of-axis response via the Diffraction tool with SB17NBAC-4
- SPL traced SB26ADC in 5" WG

Versus a simulation of SB26ADC traced from manufacturer, thus without WG:

Big improvement over no waveguide! If you are bored, try pushing that crossover point up until that DI curve is smooth as can be. I'm curious if you have to all the way to 2.5khz, or if a lower frequency can work as well.

Are you guys posting the stl files for people to print them? If so, where?

augerpro 17th January 2020 12:54 AM

My website: Waveguides | somasonus
