This video plays sound ONLY through the subwoofer (LFE channel). There is no sound from other speakers by design. This is a subwoofer only / deep sub bass test created for real 5.1 surround sound systems. It helps you test whether your subwoofer is working properly and how it responds to low frequencies.

With this test you can:
• Check the subwoofer (LFE) output
• Test deep sub bass response
• Adjust AV receiver and home theater settings
• Feel bass extension and vibration performance

Please note: YouTube on web browsers does not support 5.1 surround audio playback. To experience true 5.1 surround sound, use the YouTube app on Android TV, Apple TV, Smart TVs, or Android TV box devices.
