150 Hz → 10 Hz
Find your lowest audible bass
Start Low
Start at low volume. High SPL at extreme low frequencies can damage speakers and headphones.
Sub-bass
Feel, not heard
Deep Bass
Kick & rumble
Mid Bass
Warmth & body
Upper Bass
Punch & clarity
Speaker Placement
Place subwoofer in a corner to reinforce bass.
Headphones
Room acoustics affect bass more than any other frequency.
Free Online Bass Test
Test your speakers, headphones, and subwoofer with precision low-frequency tones from 10Hz to 200Hz. Discover how low your audio equipment can really go.
Precision Sub-bass
Generate clean sine waves from 10Hz to 200Hz. Hear exactly where your speakers or headphones start to roll off and lose low-frequency response.
How Low Can You Go?
The progressive test starts at 150Hz and descends to 10Hz. Find the exact lowest frequency your setup can reproduce — a key metric for audio quality.
Speaker & Headphone
Works with any audio output device. Compare the bass response of different speakers, headphones, and earbuds to find your best low-frequency performer.
Sub-bass vs
Mid-bass
Sub-bass (10-60 Hz)
The lowest frequencies humans can perceive. You often feel these more than hear them. Sub-bass provides the physical rumble in movie theaters and clubs.
Mid-bass (60-200 Hz)
The punch and warmth of bass guitars, kick drums, and male vocals. This range gives music its body and fullness. Most small speakers handle this range well.
Why Size Matters
Reproducing sub-bass requires moving air. Larger speaker drivers and sealed enclosures perform better at the lowest frequencies. Earbuds typically cut off around 20-40Hz.
Room Acoustics
Your room affects bass significantly. Standing waves can create dead spots and boom. Experimenting with speaker placement can dramatically improve bass response.
How to Improve Bass Response
Practical tips to get the most bass from your audio setup.
Speaker Placement
Place subwoofers in corners to use room boundaries for bass reinforcement. Avoid placing speakers right against walls unless you want emphasized bass. Experiment with the "subwoofer crawl" technique.
EQ & Settings
Use your system's equalizer to boost 40-100Hz carefully. Many devices have a "Bass Boost" option. Avoid over-boosting which causes distortion and muddy sound.
Hardware Upgrade
If your current speakers lack low-end, consider a dedicated subwoofer. It handles frequencies below 80Hz while your main speakers focus on midrange and treble, improving overall clarity.
Frequently Asked Questions
Q.What is a bass test?
A bass test plays low-frequency tones through your speakers or headphones to evaluate their low-end performance. It helps you understand the lowest frequencies your audio equipment can reproduce and how cleanly it handles them.
Q.Can bass damage my speakers?
Yes — sustained high-volume bass, especially sub-bass below 30Hz, can damage speakers not designed for it. Always start at low volume and increase gradually. If you hear rattling or distortion, reduce the volume immediately.
Q.Why can't I hear very low frequencies?
Most consumer speakers and earbuds can't reproduce frequencies below 50-60Hz. You need larger drivers (subwoofers, over-ear headphones) to hear sub-bass. Also, human hearing sensitivity drops significantly below 30Hz.
Q.What's a good lowest frequency for headphones?
Most premium headphones reach 20Hz. Budget earbuds typically stop around 40-60Hz. If your headphones can cleanly reproduce 30Hz or below without distortion, they have excellent bass response.
Q.Should I feel bass or hear it?
Sub-bass (below 40Hz) is often felt physically more than heard. This is normal. The tactile vibration you feel from a subwoofer is an important part of the low-frequency experience in music, movies, and gaming.
Q.How do I test my subwoofer?
Use the frequency slider to sweep from 20Hz to 80Hz. A good subwoofer should produce clean, undistorted output across this entire range. Pay attention to any rattling (indicating loose components) or sudden volume drops (indicating roll-off).
