General Diagnosis - Speaker Tests

TOOL REQUIRED:
J 39916-A CD and Cassette Diagnostic Kit

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

Tones are used to test and evaluate coaxial speakers or other complex speaker systems. There are three basic tones used; 50 Hz sine tone, 500 Hz warble tone, and 9 kHz spectral tone. The combination tone is a blend of the above three tones.
