Practical Considerations for Quality Control Testing of Loudspeakers

Integrating a power amplifier, microphone power supply, and analyzer required for speaker tests, the article details how the Audio Precision APx517B can save time in the overall test process through reduced setup and configuration steps. The authors also explain how this new AP solution meets the need to balance the cost of test including time, test methods, and system cost, against "the cost of failure" that might result from the expense of warranty repairs, or the possible negative impact to brand from product returns. This article was originally published in Voice Coil, April 2021.
