How low can your bass go? Find out with this subwoofer test app!


This app features precise low range sound frequencies that allow you to test the capabilities of your subwoofer speakers. Sound frequencies are measured in Hertz (Hz) and the frequencies included in this app range from 15Hz to 100Hz, with a test sound at each 5Hz increment. Including test sounds in 5Hz increments allows you to more accurately pinpoint the lowest range that your audio system can play. Humans can begin to hear tones at around 20Hz, so having an audio system with capabilities to play sounds lower than this typically isn't necessary!
