Bass Test / Subwoofer Test

Test your subwoofer or bass speakers with frequencies from 10Hz to 200Hz. Use the slider to pinpoint specific bass frequencies, or run an auto-sweep to test the full bass range. The surround sound test is the fastest way to verify your surround sound configuration after moving or rebalancing speakers.

Turn volume up gradually — bass frequencies can be very loud
Select a channel, adjust the frequency, then press Play.

What Does a Bass Test Check?

A bass test plays low-frequency tones through your subwoofer or bass speakers to reveal how your audio system handles frequencies below 200Hz — where rumble, impact, and warmth live. The audio latency test reports your device's audio output latency in milliseconds — useful for gaming and production.

Most consumer subwoofers roll off below 40Hz, and any gap in the 60–80Hz range noticeably reduces punch in music. Identifying these gaps helps you adjust crossover settings or equalisation. The tone generator produces sine, square, sawtooth, and triangle waveforms for testing or calibration.
