Okay so I searched all over the Web for the resonance frequency of my car speaker so I can properly apply crossover filters, but didn't found any reference of the resonance frequency of this speaker model.
So how can I calculate it?
I have the following data:
Peak power: 150w Rms power: 20w Response Frequency: 90Hz-20kHz Sensitivity: 91db/W/m 4 ohm
Thank you in advance!!
