This is a little lengthy, but bare with me. It was created upon request. The information here is for informational purposes only and does not contain much about helping with design, as those parts were intentionally left out for now. The response information here was measured and calculated in a much quicker manner than usual and maintains a sense of realism and honesty. Please enjoy.
This is an introduction to the basic form I use to figure an accurate response based on the added gain of the vehicles transfer function. This is only for my personal vehicle, and the cabin gain shown will not be reflected by an average, nor does it relate to any other vehicle on the market. Most designers who do inhabit cabin gain, use very generic forms of averaged dB increases per octave of somewhere between 6-12dB.
This will show you the accuracy of my design process and hopefully conclude the theory/practice misconception that hovers over the audio community based on inaccurate design approaches, that have damaged the trust of a proper calculation in this world in comparison to real world response.
I am going to be using a generic 6.5” driver with an Fs of around 57-62Hz, depending on the applied voltage, related to impedance changes.
Information will be added each post due to the length of the project.
