Speaker Noise - General

TOOLS REQUIRED
J 39916-A CD and Cassette Diagnostic kit

IMPORTANT: Always compare the front speakers to the front, and the rear speakers to the rear. Do not compare the front speakers to the rear speakers because the speakers may be different or their mounting environment could cause them to sound different.

The tones are used to test and evaluate coaxial speakers or other complex speaker Systems. The following three basic tones are used:
^ The 50 Hz sine tone
^ The 500 Hz warble tone
^ The 9 kHz spectral tone
The combination tone is a blend of the three tones.
