Speaker Simulator Comparison Test

Frequency Response

After having heard the differences and similarities between the speaker simulators you might be interested in their frequency responses. Of course there are more parameters influencing the sound of a speaker simulator, but the graphs below show you some similarities, which can also be heard.

I have used the tool fgang for measuring and graphing the frequency responses. It's as easy as feeding a generated audio signal into a device and recording its output.

You can click on a graph picture to open a larger version of it.
