To
my speaker, start by inspecting the power source, cables, and input sockets. Try using a different device to test the speaker to determine if the problem is external. Pay attention to symptoms such as distortion, buzzing, or nothing, which point towards the fault. Inspect the speaker cone visually for tears, dents, or rigidity, and press gently to ensure smooth movement—resistance or scraping might indicate a damaged voice coil. If safe to do so, unplug and disassemble the speaker. Check for loose wires, burned parts, blown fuses, or cracked solder joints. Test continuity between terminals and crossover circuits using a multimeter. Remove internal dust or corrosion, re-solder loose joints, and replace any damaged components. For wireless or Bluetooth speakers, reset the unit, update firmware, and inspect battery health. Once repaired, reattach the speaker firmly and play a soft sound. If the problem persists or you are not sure, it would be wise to have it examined by a professional technician.
