Hello everyone,
I’m excited to share that I’ve launched a basic course on Thiele-Small Theory on YouTube! In this course, I dive into the mathematical modeling of a speaker inside a box, covering all the math behind it. I explain the equivalent circuits for different box types, starting with sealed enclosures and progressing through bass reflex, 4th order band-pass, and more.
So far, I’ve posted 4 videos, and there’s much more to come. Each box design is modeled in MATLAB, and the results are compared with WinISD. In my latest video, I implemented a Particle Swarm Optimization (PSO) for the 4th order band-pass. In this example, I define target start and stop frequencies where I want the response to be as flat and loud (in terms of SPL) as possible. The PSO then optimizes the box’s rear and front volumes and the vent size to achieve the best results.
The ultimate goal is to use PSO to design an 8th order band-pass, and then build the enclosure for real-world validation.
While the videos are in Portuguese (since I’m Brazilian), there are plenty of equations and diagrams, so if you enable automatic subtitles, you should still be able to follow along.

Thank you for your attention!

Greets!
Thanks for your efforts, but FWIW, best to have based it on Hornresp or similar to include the increasingly more popular TL, horn alignments or at least include them in the near future.

Good day! I'm currently comparing with WinISD, though there's no particular reason for this choice—it could just as easily be Hornresp. In fact, I've already compared my results for the 8th-order band-pass with Hornresp, and the outcomes are very similar.
However, the video on 8th-order band-pass boxes isn't ready yet.
Regarding horns and other similar box types, I'm not focusing on them at the moment, but who knows what the future holds...
