Why do my speakers crackle or distort?
Answer speaker crackle and distortion, including volume clipping, cable faults, one-channel failure, driver damage, and frequency tests.
Short answer
Crackle is often the signal path clipping before it is a blown speaker. Lower volume, simplify the cable path, test left and right separately, then use tones to find whether distortion follows one speaker.
Confirm first
Lower source and speaker volume.
Run a left-right test.
Use tones to find repeat distortion.
Why this matters
HWProbe keeps the answer tied to evidence: run the matching browser test, try the reversible fix, then replace only when the same fault repeats. Tests run locally in your browser at hwprobe.com.

Frequently Asked Questions
Can high volume make good speakers crackle? +
Yes. Source clipping, amplifier clipping, and excessive bass boost can make healthy speakers distort. Lower the source volume and speaker volume separately to isolate it.
How do I know if one speaker driver is blown? +
If distortion follows the same physical speaker across channels, cables, and devices, the driver or enclosure is more likely damaged.
