Interpreting Test Results: Common Failures and Fixes

You’ve run the test. What do the results mean?

| Symptom During Test | Likely Problem | The Fix | | :--- | :--- | :--- | | No sound from Rear Right | Loose wire or blown speaker | Swap the cable with the Rear Left. If the problem moves, the wire is bad. If not, the speaker is blown. | | The Center channel sounds muffled | Crossover set too low (e.g., 40Hz) | Raise crossover to 80Hz or 100Hz. Center speakers are small by design. | | The subwoofer stays silent | LFE channel turned off in player | Go to player settings: Change "Subwoofer" from "Off" to "On" or "LFE Only." | | Voices echo in the rears | Up-mixing mode is on (e.g., Dolby Surround) | Set receiver to "Straight," "Direct," or "Pure Audio" for native 5.1/7.1 content. | | Bass is weak when sub is on | Phase cancellation (sub and mains) | In receiver settings, flip the "Subwoofer Phase" from 0° to 180°. Listen for louder bass. | Technical Assessment Report: 7
