Bass Test

Find where your bass really stops. Seven fixed tones from 20 to 100 Hz plus a slow low-end sweep - the lowest one you can hear cleanly is your gear's true floor.

⚠ Start at low volume. Sustained low tones at high level can bottom out subwoofers and overheat small drivers.

Reading your results

Tone is silent: below your gear's range - normal for 20-40 Hz on anything without a subwoofer. Tone sounds higher-pitched than the next one up: you are hearing harmonic distortion, not the fundamental. Buzzing or rattling: something loose - the driver, the grille, or the furniture; the speaker cleaner handles debris. Loud at one spot in the sweep, dead at another: room modes - map them with the room mode calculator. For deeper diagnosis, step down to single hertz precision with the subwoofer test or dial in exact frequencies with the bass tone generator. Quick overall check first? Run the 30-second sound test.

Bass Test FAQ

What bass should my gear reproduce?

Rough expectations: laptop speakers give out around 150-200 Hz; small Bluetooth speakers around 80-100 Hz; decent bookshelf speakers reach 50-60 Hz; good over-ear headphones reproduce 20-30 Hz (quietly but audibly); a real subwoofer should produce clean output at 25-30 Hz and many reach 20. If a tone two steps above your gear's rating is silent, check volume and placement before blaming the hardware.

I hear something on the 20 Hz tone through small speakers - how?

What you hear is almost certainly harmonic distortion, not 20 Hz. When a small driver is pushed below its range it produces overtones at 40, 60, 80 Hz that your brain accepts as "a low note". A quick check: if the 20 Hz "tone" sounds similar in pitch to the 40 Hz one, you are hearing the distortion, not the fundamental.

Why does the bass get louder and quieter as I move around the room?

Room modes: low-frequency waves are meters long and reflect between parallel walls, creating spots where the wave stacks up (boomy) and spots where it cancels (dead). This is a room property, not a speaker fault. Find your problem frequencies with the room mode calculator, and test from your actual listening position.

How loud should I play these tones?

Start around a quarter volume and raise it gradually. Low frequencies feel quieter than they measure - equal-loudness curves mean 40 Hz needs far more energy than 1 kHz to sound equally loud - so it is easy to drive a small speaker into distortion or bottom out a subwoofer without realizing. Rattling grilles and buzzing panels mean back off.
