The Bass Test plays frequencies from 10Hz to 200Hz through your subwoofer or bass speakers so you can check how low your system actually reaches. Drag the frequency slider to pinpoint a specific tone, set your volume, and click Auto Sweep to run the full bass range and listen for rattles or missing output. Run the test your sound to see exactly what's working and what isn't. The headphone frequency and stereo imaging test takes under a minute and needs nothing but your browser.

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. Try the free free gaming headset test for a quick, no-install way to check this yourself.

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.
