How to use

How to run bass and frequency checks

Use Bass presets (60 / 100 / 250 Hz) for low-end checks, Frequency mode for fixed tones, and Sweep to glide from about 40 Hz to 12 kHz.

Small laptop speakers and tiny earbuds may not reproduce deep bass—that is a hardware limit, not necessarily a fault. Stop immediately if tones feel uncomfortable.

Pair this page with the left-right and stereo tests when diagnosing “no bass”, “tinny sound”, or uneven frequency response on Bluetooth speakers.

  • Start at low volume—bass energy can rattle loose panels or damage weak drivers if driven hard.
  • Room placement and EQ apps strongly affect perceived bass.
  • Sweep is for listening checks, not calibrated lab measurements.

Bass FAQ

Bass and frequency questions

What frequency should I use for a bass test?

Start around 60 Hz for sub-bass feel on larger speakers, then try 100 Hz and 250 Hz. Many portable speakers roll off well above true sub-bass.

What is a frequency sweep speaker test?

A sweep continuously changes pitch so you can hear dropouts, rattles, or harsh peaks across a range instead of a single fixed tone.

Why is there no bass on my Bluetooth speaker?

Size, EQ profiles, power limits, and codec processing all reduce low end. Compare with headphones and another source before assuming a defect.

Is a browser bass test accurate?

It is excellent for quick comparative listening, but not a replacement for calibrated measurement microphones or lab gear.
