Important
^ Always compare the front speakers to front and the rear speakers to rear. Do not compare front speakers to rear speakers, because they could be different speakers or their mounting environment could cause them to sound differently.

Tones are used to test and evaluate coaxial speakers or other complex speaker systems. There are three basic tones that are used. They are as follows: 50 Hz Sine Tone, 500 Hz Warble Tone and a 9 kHz Spectral Tone
