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.
