What is a good bass test frequency?

Start at 60 Hz, which every decent speaker and headphone should play clearly. Then step down: 40 Hz is the bottom of most music, 30 Hz separates good systems from great ones, and 20 Hz is the official bottom of human hearing. Use the presets in the tool, or Find my lowest to step down automatically.

Can a bass test damage my speakers?

Yes, at high volume. Pure low tones make a speaker cone move much further than music does. Small speakers and laptop speakers can “bottom out” (a harsh slapping or crackling sound), which can damage them. Start with your system volume low and turn up slowly. Stop immediately if you hear rattling, crackling or distortion. The tool caps its own output at −6 dB for this reason.

Why can’t I hear 20 Hz?

Most speakers can’t play it, and even when they do, your ears are very insensitive at that frequency. A 20 Hz tone has to be roughly 70–80 dB louder than a 1 kHz tone to sound equally loud. Phones, laptops and most desktop speakers stop well above 20 Hz, so silence there is normal. Subwoofers and well-sealed headphones are the main exceptions.

Why do I feel the bass more than hear it?

Below about 30 Hz, very loud bass is sensed partly as pressure on your chest and body, not just through your ears. With headphones there’s no body contact, so deep bass can sound thinner than on a subwoofer even if the headphones measure flat.

Does this bass test work for headphones and earbuds?

Yes. In-ear and closed headphones need a good seal to produce bass. If bass suddenly gets much louder when you press the earbuds in gently, try a larger ear tip size. The headphone test has a dedicated fit and seal check.

What frequency is a bass drop or sub-bass in music?

Most electronic “sub drops” and 808 bass notes sit between 30 and 60 Hz. A kick drum’s body is around 50–80 Hz, and its click is much higher, around 2–5 kHz. The lowest note of a standard 4-string bass guitar is E1, at 41 Hz.

Is a bass test the same as a subwoofer test?

This test checks how low any speaker or headphone goes. The subwoofer test adds tools for setting up a subwoofer with main speakers: crossover blend, phase, rattle hunting, and measuring your room’s bass response with a microphone.

Bass Test – Check How Low Your Speakers Go (10

How to use the bass test

Turn your system volume down to about a quarter. Low tones carry a lot of energy. Turn up gradually once you know how loud it is.
Press Play tone. You’ll hear a steady 60 Hz hum, the heart of the bass range.
Drag the slider left or tap a preset to go lower. Listen for where the hum fades out, turns into a buzz, or makes something rattle.
For a quick answer, switch to Find my lowest. It steps down from 150 Hz to 12 Hz on its own. Press the big button when the tone disappears.
Check real-world bass with the Music loop. Pure tones show the limit. The loop shows punch and how bass sounds on music.

The bass test playing a 40 Hz tone, with the frequency readout, slider, play button, presets and volume labeled — Switch between a steady tone, the automatic *Find my lowest* test and the music loop.
Current frequency and which part of the bass range it’s in.
Drag to choose any frequency from 10 to 200 Hz. The slider is logarithmic, so each octave gets equal space. Arrow keys fine-tune.
Start and stop the tone. You can also press `Space`.
Jump straight to common test frequencies.

Find my lowest mode showing its result: your system plays down to about 45 Hz — A finished *Find my lowest* run. The result is the last step you could still hear.

Bass frequencies explained

“Bass” covers roughly 20 to 250 Hz, a range of more than three octaves. Each part does a different job in music and films. Press play to hear each one. If a button seems silent, your speakers probably don’t reach that range.

Range	What lives there	Hear it
Below 20 Hz	Infrasound. Felt more than heard: earthquakes, pipe organs’ lowest pipes, some film effects.
20–40 Hz	Deep sub-bass: synth sub drops, 808s, explosions and rumble in movies.
40–60 Hz	Kick drum body, bass guitar low notes (low E is 41 Hz), the “weight” in music.
60–120 Hz	Punch and warmth: kick drum thump, bass guitar fundamentals, the depth of male voices.
120–250 Hz	Upper bass: fullness. Too much sounds boomy or muddy; too little sounds thin.

Your hearing is far less sensitive to low frequencies. At the same volume setting, 30 Hz sounds much quieter than 100 Hz, even on a speaker that plays both equally well. So a low tone that seems faint isn’t necessarily a speaker problem.

Typical results by device

Device	Usually plays down to
Phone speaker	150–300 Hz
Laptop or tablet speakers	100–200 Hz
Small Bluetooth speaker	60–100 Hz
Desktop or bookshelf speakers	40–60 Hz
Headphones and sealed earbuds	20–40 Hz, often lower
Floor-standing speakers	30–45 Hz
Subwoofer	20–30 Hz, some lower

Why small speakers still seem to have bass

A phone can’t play 55 Hz, yet you can still follow a bassline on it. That’s because a real bass note isn’t a single frequency. It’s a fundamental plus a series of harmonics at 2×, 3×, 4× that frequency, and so on. When the fundamental is missing, your brain reconstructs it from the spacing of the harmonics. This effect is called the missing fundamental.

Try it. Both sounds below have the same pitch, a low A at 55 Hz. The second one has no 55 Hz in it at all, only harmonics at 110, 165, 220 Hz and up:

On headphones or a subwoofer, the first sounds deeper and fuller. On a phone or laptop they sound almost identical, because the speaker can’t play 55 Hz anyway. This is why a bass test with pure tones is the honest way to see how low your speakers go: a pure tone has no harmonics to fool you.

If a low tone turns into a buzz or a higher-pitched note, the speaker is distorting. It’s creating harmonics that weren’t in the signal. That’s a sign you’ve reached its limit, so turn it down.

How to get better bass

Speakers

Move them closer to a wall. Placing a speaker near a wall boosts its bass by up to 6 dB, and a corner boosts it even more. If bass is boomy, pull speakers 30–60 cm (1–2 ft) away from the wall.
Don’t block rear ports. Many speakers have a port (hole) on the back that produces bass. Leave at least a few centimeters behind it.
Move your listening position. Rooms create bass peaks and nulls. Moving your chair by half a meter can change the bass dramatically. The subwoofer test can measure this with your microphone.
Add a subwoofer if your speakers stop around 50–60 Hz and you want the deepest bass in films and electronic music.

Headphones and earbuds

Get a proper seal. This is the biggest factor by far. A small gap around an earbud can cost 10–20 dB of bass. Try every ear tip size, and foam tips if you can.
Glasses and hair break the seal of over-ear headphones and reduce bass noticeably.

Settings

Use the bass or low-shelf control in your music app, player or system EQ, but boost gently (3–6 dB). Large boosts eat into the speaker’s headroom and cause distortion.
On Windows, check the sound device’s Enhancements or your audio app (Realtek, Dolby, Nahimic). A “bass boost” option may be on or off without you knowing.
Turn off “battery saver” or “volume limiter” modes on Bluetooth speakers. Some cut bass to save power.

Rattles, buzzing and distortion

Slowly sweeping a bass tone is the fastest way to find rattles: a loose shelf, window, screw in the speaker grille, or a damaged speaker cone. Move the slider slowly between 30 and 120 Hz at moderate volume and listen for buzzing. When something rattles, hold the frequency there and walk around the room to find it.

If the buzz comes from the speaker itself, gently press on the cabinet and grille. If it continues, the cone or surround may be damaged. Compare it with the other speaker, as a healthy speaker produces a clean hum at the same frequency and volume.
