2nd Order Crossover Network Experiment For Car Audio

When I building multi way speaker system, I mostly using the 2nd order crossover for the starting point. Then, one by one I experimenting to the higher order cross over slope to get the better result from each drivers.

The tweeter installation previously on my car here is only using the first order cross-over for both drivers. This is by only using 1 capacitor for the tweeter and 1 inductor for the mid-range. I know at that time I had a short time installation but I will revised it in today upgrade. I will rebuild the cross-over and upgrade it to the 2nd order slope.

Building 2 Way SB Acoustic Speakers (Part 2) The Crossover Network

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 comparation between his schematic to the others, I found that this SB Acoustic official web is more suitable for my speaker project.

So I build this crossover network based on that websites as the basic idea.

Sony CDX CA900 Car Head unit Installation

The OEM head unit always greet me with enjoy Honda. Okay, thank you. So nice to have the head unit that greet me all the time I turn on the key. Personally I love driving this car, but for the OEM audio quality is not.
