Course Overview
Design and build sealed, ported, passive radiator, 4th order and 6th order bandpass enclosures
Start designing more advanced enclosures
Finished Acoustics 101? Time to step it up a notch. While we are still going to revisit sealed and bass reflex enclosures, we are going to go deeper into the subject, and touch more advanced stuff. As a bonus, a high output ported enclosure is in the course as well. Besides these familiar enclosures, we going to see some new. Get ready to learn about passive radiator enclosures, 4th order and 6th order bandpass boxes.
Software
Yes, we are going to use software, WinISD. Popular software in the DIY audio community, with lots of features. Don't worry, you can download it for free. What you also get for free is a bunch of excel spreadsheets. These will be used to easily calculate the panel dimensions for each enclosure type. Even if you are not good at math, I'm confident you will find it easy.
3D Modeling
After the enclosures are modeled and the panel dimensions are calculated, we are going to use SketchUp to make 3D models of the enclosure. This has a number of benefits. You can visually check the proportions of the enclosure. You will double check if the panels fit together correctly. You can send someone the drawing with the dimensions. You can do all sorts of things if you expand on this subject. However, bear in mind that this is not a SketchUp course, and it covers only the basics and the stuff you need to make a 3D model of a speaker box.
Building and results
The final part of the course will be me showing you how I build each enclosure. I will describe what I do and you will learn some basic stuff about woodworking so you can build your own speaker boxes (tools required). Each enclosure will be measured and tested. If you have taken Acoustics 201 you will understand what I'm doing, but it's not mandatory. In the end we will compare how each enclosure stacks up to one another by judging the numbers.

It's a good stuff

I thought this course was great. The only suggestion or thing I thought was missing would have been measuring your own speakers that may not have perfect TS parameter data (or none at all) using DATS or similar. It would also have been nice to test / discuss builds for hifi in addition to car audio environments (even though there was some discussion on why people use small cars for SPL comps).

That's amazing! This is really a good course where we can learn theory, software application and practice. The only thing I missed is explanation about the maximum cone excursion and how to use crossover filters to limit it in flat responses.
