This may seem like a technicality until you run a sine sweep or a 20 KHz tone through the analyzer and find that large sections of the input simply aren't displayed on the analyzer screen. Looking at these kinds of test signals on a spectrogram is the primary way that we test and evaluate the quality of audio effect plugins.

A spectrum analyzer is merely a visual representation of the signal, it is in no way an accurate representation of what your speakers are actually producing. That is the difference between a 'spectrum analyzer' and a true 'real time analyzer'. You can learn a little bit from a spectrum analyzer, but realistically not very much.
