I'll be ready to test the tuning of my DIY sub - the one I'm calling the Heretic.
I have access to a very cabable frequency generator (a Doble unit with variable frequency output, adjustable current outputor adjustable voltage ), and can also put out huge power while doing any freq.
I understand that with the driver installed and the box sealed, I would apply a frequency of, say 20 hz, at a fixed voltage and measure the current with a true RMS ammeter, plot the current vs. freq, then repeat at 20.5 hz, 21 hz, etc.
The tuning frequency is where the system impedance is the highest which should be indicated by the lowest current reading, am I on the right track?
