Speaker Frequency Test
Play low, mid, and high tones to check bass, treble, resonance, distortion, and practical frequency range on your current audio output.
Current tone settings
Preset buttons are great for quick checks; sliders help you isolate suspicious ranges.

Jump quickly between common bass, midrange, and treble checkpoints.
Custom tone generator
Use this when you want to narrow down where distortion, weakness, or resonance begins.

What to listen for
A focused tone is useful because it removes musical complexity and exposes the problem directly.
- Missing low bass is normal on small speakers but suspicious on a proper subwoofer setup.
- Buzzing at specific frequencies often means resonance, loose parts, or driver damage.
- Painful or harsh highs may reveal distortion, EQ problems, or poor transducer behavior.
- One-sided weakness should be confirmed with a dedicated channel test next.
If channel routing is the main problem instead of frequency behavior, open the Left / Right Speaker Test.
Frequently Asked Questions
How do I test speaker frequency response? +
Start at low volume, sweep gradually from bass to treble, and listen for dropouts, rattles, harsh peaks, or distortion. Keep volume moderate to avoid stressing small speakers.
Why can't I hear low bass tones? +
Small laptop, monitor, and portable speakers often cannot reproduce deep bass. If low tones vanish below the speaker's physical range, that is a limitation rather than a browser failure.
Why do speakers buzz at one frequency? +
Buzzing at one frequency often means resonance, a loose object, a damaged driver, or cabinet rattle. Move nearby objects, lower volume, and test each channel separately.
