In this video I evaluate and test a pair of Yamaha NS-690 II speakers for proper function. These speakers were brought in with a Kenwood KR-9400 stereo receiver that they were paired with. The customer was experiencing loud crackle and pop noise that he felt may be associated with the speakers. Both the receiver and the speakers were evaluated and tested individually and together to determine the origin and cause of the problem...if any.
