Test suite addresses audio test quality for loudspeaker driver production and final QA
14.00
In less than one second, the Loudspeaker Production Test measurement returns multiple results: rub and buzz, impedance magnitude and phase, key Thiele-Small parameters, SPL, frequency response, phase, and distortion (either total or specific harmonics). Polarity can be evaluated with the built in phase measurement, or by a separate half-second measurement. If required, air leak detection is measured in another half-second measurement. An APx analyzer is required to run the measurements. All normal APx functionality, such as floating limits based on a golden unit, smoothing, one-click automation and automated reporting are also available.
In addition to the Loudspeaker Production Test suite, a new R&D suite has also been released. The new Impedance/ Thiele-Small measurement enables complex impedance and full Thiele-Small parameters. Waterfall (CSD) and polar plots have also been added.
