\"1645038132-3fc2f933557d8fd\"\uffe5Design an enclosure to match your preferences<\/strong>
The main purpose of this course is to teach you how to properly design an enclosure for your speaker. There is no such thing as \u201cThis enclosure is the best choice for this particular speaker\u201d. You have to take into consideration your application and your personal preferences. Do you want it to sound loud Do you want it to sound deep and don\u2019t 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. The final result will always be a compromise between the acoustical qualities of an enclosure. Only you can decide which sound qualities are more important to you and you should be the one who \u201cmoves the sliders\u201d.<\/p>\n

Acoustics basics<\/strong><\/p>\n

  <\/p>\n

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\u2019s also good for an intermediate student, as I\u2019m sure he will also find new information to make matters even more clear.<\/p>\n

  <\/p>\n

Enclosure types<\/strong><\/p>\n

  <\/p>\n

Most of the common enclosure types are listed, explaining their working principle, pro\u2019s and cons for each one. But, we will focus our attention for the sealed<\/strong> and bass reflex<\/strong> 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.<\/p>\n

  <\/p>\n

Modeling software<\/strong><\/p>\n

  <\/p>\n

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\u2019s 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 : \u201cSubwoofer design toolbox\u201d. The main reasons are : it\u2019s cheap, simple, easy to understand and it has all the basic functions. If you are a beginner it\u2019s very important to start slow, otherwise you will get overwhelmed by complicated applications with extra features that will only confuse you.<\/p>\n
