A speaker leak test system which quickly tests if a speaker enclosure is sealed properly. The speaker leak test system tests for air leaks in the speaker enclosure, which air leaks degrade the acoustic performance of the speaker. A vacuum (or pressure) source is connected through a vacuum hose to the speaker enclosure and vacuum is drawn. After a test vacuum level is reached, the mass air flow through the vacuum hose is measured. If the mass air flow does not exceed a pre-determined speaker dependent threshold for the speaker under test, the speaker is declared to be leak free. A bypass solenoid may reside in parallel with a mass air flow sensor to reach test vacuum quickly. This speaker leak test system is intended to be used in a prototyping and production environment and tests the speaker enclosure for leaks both quickly (e.g., less than five seconds) and accurately.
