THD Test Drive

Take the THD Test Drive. Watch each video and learn how different inductors output Total Harmonic Distortion under various power settings. This will help you choose the perfect ERSE coil for your system. Choose a video from the list. We suggest that you start with the AMP Overview. This video is an intro to the other THD Test Drives and will explain how the tests work. ERSE Engineers tests our products daily. If you would like to see a THD Test Drive of another ERSE product please send us a message. We will be happy to display the results.
