Video: Polk car speaker testing
Extreme testing to create high quality speakers
Heads up!Welcome to this article from the Crutchfield archives. Have fun reading it, but be aware that the information may be outdated and links may be broken.
Our video team traveled to Polk Audio to check out the extreme tests that their car speakers undergo. These speakers go through a period of high/low temperature and humidity testing, as well as a six-week long test where they alternate between Polk's salt/fog tester and UV tester.
