Acoustics basics
This course assumes that you have minimal knowledge about acoustics, and therefore starts slowly with some basic information about sound waves, how they are created and what are their characteristics. Then moves on to how the speaker is designed and some other relevant information about acoustics. This is obviously needed for a beginner, but it's also good for an intermediate student, as I'm sure he will also find new information to make matters even more clear.
Enclosure types
Most of the common enclosure types are listed, explaining their working principle, pro's and cons for each one. But, we will focus our attention for the
sealed and
bass reflex enclosures. These are covered with extensive details regarding their characteristics and how to design them according to the standard alignments, or to complete custom response curves.
Modeling software
To model the response curve of the enclosure and to calculate the dimensions of the box, two methods will be used. You will receive an excel spreadsheet, that has all that you need to model a sealed or a bass reflex enclosure with minimal difficulty. It even has a chart to show you the modeled frequency response. It's basically a complete package for a beginner. The other method is by using a paid application. There are a lot of speaker design software solutions out there but I chose : "Subwoofer design toolbox". The main reasons are : it's cheap, simple, easy to understand and it has all the basic functions. If you are a beginner it's very important to start slow, otherwise you will get overwhelmed by complicated applications with extra features that will only confuse you.
Who is the target audience?
•Audiophiles who want to learn more about sound and speaker systems.
•DIY-ers who want to build their own speaker enclosure.
•People who built enclosures by following some speaker plans, but want to understand the design process.
•People interested in acoustics and electro-acoustics
