you helped me a lot..could listen you for days
- Stefan Petak
very informative.
- Tanner Dickerson
Muy buena elección. Debo observar que en algunos momentos no se corresponden los subtítulos con el audio, tiene algunos errores. Tal vez habría que realizar algunos acercamientos haciendo zoom sobre la pantalla del room EQ, para mejorar la imágen.
- Enzo Scarponi
Marius has been very inspiring. I have many experience in loudspeaker building and I was not expecting many from this course but It reminded me and organized in my head a lot of basics. Some new things too. Im looking forward to the next course. Great work Marius!!
- Nestor Varela
Very informative. Will have to redo the course a couple of time but just what I wanted
- Wynand Nieman
So far the course is what I was expecting
- Kyle Lautzenhiser
So far the level of detail is appropriate for an intermediate student. I am interested in seeing later chapter were test equipment set-up is discussed.
- Ed Lindsey
- John Thompson
With delving into the world of diy speaker building, this course was a great help when it comes to doing the measurement side of things. It answered a lot of questions on what and how to measure as well as interpreting the results. Cant wait for the crossover course!
- Simon Wright
The lessons are very easy to understand because there are a lot of pictures and the explanations are very clear. The course is mainly focused on the enclosure so in the end the loudspeaker design need more lessons and studies. I hope there will be an advanced course soon.

About the author
I’m Marius, the guy behind Audio Judgement. If you are familiar with my blog then you know I’m passionate about audio and started learning about this field several years ago. Not many instructional videos about this topic, so that’s why I made these video courses on Udemy. Hope they help you out.
