Speaker Frequecy Graphs???

For some reason, they don`t work as well as ears.

 

I think they are mostly useless.

They don't tell you about relative distortion, compression, and other sonic colorations.

Use yer ears!

What Ken says. They are almost totally useless from a 'tone' point of view, because they are the results of feeding single (usually sinusoidal) frequencies in. They tell you nothing about how the speaker reacts to a complex sound - even a single clean guitar note is composed of many frequencies, let alone anything distorted - or a chord.

With a speaker with a complex non-hi-fi response (like any good 'guitar' speaker) this makes a HUGE difference in the 'sound' that comes out.

The graphs do give a very rough idea of the overall sensitivity and where you might expect the 'peak' response to be, but no more than that, and the results in practice can be quite different.

 

Here's something I posted a few months ago, not sure how useful it was:
