Everyone has heard of the mystical term impedance rise, but more & more I read and hear people saying “I’m not worried about that yo…”
Well, sad to say, but that person will not see what they expect from their Acme 9000.
Why? Impedance rise.

This procedure also can be used to find the real world tuning of any ported enclosure, in a given install.
More importantly, in my opinion, the second method gives the example of the best way to go about seeing what you amplifier ‘puts out’. With regards to this, any given amplifier will produce different results in different install.

With either method, You are going to need a few basic things:
    *At least one Voltmeter (VAC) –or- DMM.
    *A supply of test tones. Preferably 20-80hz - NOT a sweep
    *An audio system: Signal source, amplifier, drivers, enclosure
    *A calculator of spreadsheet program.
    *Pen & Paper


Throw in a clamp meter –or- a resistor (Radio Shack) and you’re in business.
