In this post I will building the crossover network for this SB Acoustic speaker project. Building a crossover network is not an easy job. Especially to determined the frequency cutting point and slope, then a proper measurement should be done correctly. Each crossover's components value is also very critical, especially when designing for the high pass filter. Then, when it is finished, it require to test by listening the result. On many cases, the sound need to be corrected by changing the components value by trial and error. This is a long project if I start from the scratch. So to make it more simple, I was searching any information related to the driver that I am using in this project. I found this blog , which this gentlemen is very helpful to give many information related to his speakers project using SB Acoustic drivers. His project is called LARK. My speakers box dimension almost exactly the same to his drawing. Then for the crossover schematic, after I did a co...
