There are a number of ways to determine the frequency repsonse of a system such as a loudspeaker. In all of these methods it is assumed that any other transducers in the system, such as the measuring microphone, are calibrated and the proper .CAL file is loaded in the User Line dialog with User Units active so that the overall system response is "perfect" except for the unit under test.

In the following discussion it is assumed that the tested unit is a speaker, and a calibrated microphone is used. The same general approach can be used in the reverse situation where you have a calibrated sound source and want to measure the frequency response of a microphone. See Microphone and Speaker Calibration for additional details.
