  • Verify that the AVR/amplifier sia acceso e impostato sulla sorgente di ingresso corretta.
  • Confirm that the center channel output is enabled and not muted in your AVR's settings.
• Suono distorto o poco chiaro:
  • Check speaker wire connections for any loose strands that might be touching each other or the opposite terminal.
  • Reduce the volume level on your AVR/amplifier to see if distortion decreases.
  • Ensure the speaker is not placed too close to walls or corners, which can cause excessive bass or resonance.
  • Run your AVR's room correction calibration again.
• Uneven Soundstage:
  • Confirm the speaker is centered relative to your viewing/listening position.
