Select Calc Freq Resp under the Analysis menu (or use Ctrl+F from the keyboard). ... Typically a woofer system will have an impedance peak at the systems' low frequency resonance or two peaks in the case of a vented box. At higher frequencies the speakers impedance will increase due to the effect of voice coil inductance. See Fig. 14 below.

Resonance is an important phenomenon to understand when dealing with the forced vibration of a multi-degree-of-freedom system. Resonance will occur when the driving frequency matches one of the eigenfrequencies of the system. An example of this would be a driven two-mass, three-spring system where the motion can be described by Equation 8.

with voltage alternating between +5 V and 0 V. Note that this is equivalent to switching a DC voltage on and off (grounded). View the voltage across the function generator on channel-1 of the scope and the voltage across the capacitor (V C) on chnl-2.Make sure you consider that the scope has a single ground (outer contact on the BNC connector), so that you don’t short out any circuit elements.
