Regarding the audiophile part of me, I started to intensely study this area since several years ago. Hi! My name is Marius and I'm from Romania. I majored in economics and computer science, and have a college and masters degree in this field. Jul 2020 Update - Added more animation to some lessons. Jan 2018 Update - Added English subtitles. Nov 2017 Update - 2-way speaker build example and basic 2-way crossover design.
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. The main reasons are : it's cheap, simple, easy to understand and it has all the basic functions. There are a lot of speaker design software solutions out there but I chose : "Subwoofer design toolbox". The other method is by using a paid application. It's basically a complete package for a beginner.
It even has a chart to show you the modeled frequency response. You will receive an excel spreadsheet, that has all that you need to model a sealed or a bass reflex enclosure with minimal difficulty. To model the response curve of the enclosure and to calculate the dimensions of the box, two methods will be used. 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. But, we will focus our attention for the sealed and bass reflex enclosures. Most of the common enclosure types are listed, explaining their working principle, pro's and cons for each one. 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. Then moves on to how the speaker is designed and some other relevant information about acoustics. 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. Only you can decide which sound qualities are more important to you and you should be the one who "moves the sliders". The final result will always be a compromise between the acoustical qualities of an enclosure. Do you want it to sound loud? Do you want it to sound deep and don't care about loudness? You want it to be as smooth and linear as possible? These are all just a few examples of questions that needs answering before you get to work. You have to take into consideration your application and your personal preferences. There is no such thing as "This enclosure is the best choice for this particular speaker". The main purpose of this course is to teach you how to properly design an enclosure for your speaker.
