Visualize the impedance curve of your speaker across frequency. Analyze resonance peaks,
crossover behavior, and speaker load for accurate system design.
How to Use the Impedance Plotter
This tool plots the speaker's impedance curve across the selected frequency range. Use it to:
Identify resonance peaks at Fs and impedance rise.
Analyze crossover impact on speaker load.
Ensure amplifier compatibility and avoid clipping.
Compare nominal vs peak impedance for system design.
Set the frequency range (start and end Hz).
Enter speaker nominal impedance, resonance frequency, and peak impedance.
Set the number of points for plot smoothness.
The chart will update automatically to show the impedance curve.
This Gaussian approximation simulates the resonance peak of a typical speaker.

FAQ
It shows how a speaker's impedance changes across the frequency spectrum,
helping
to design amplifiers, crossovers, and prevent overloading.
Series adds the impedance of speakers at each frequency, increasing total load,
while
parallel reduces overall impedance.
Yes, you can simulate series or parallel configurations for two identical
speakers. For
more complex setups, multiple instances or advanced curves may be needed.
Speakers exhibit mechanical and electrical resonance, causing the impedance to
spike at
a certain frequency.
The plot helps identify low impedance dips or resonance peaks. Amplifiers should
not be
driven below their safe load limits to avoid overheating or damage.
