Loudspeaker Phase Checker

Test if your stereo speakers are wired correctly in phase.

IN PHASE (0°)

The sound should feel solid, centered, and full. If it sounds hollow or swishy, click 'Invert Phase' to check the difference.

Sit exactly in the center between your two speakers. The "In Phase" tone should sound like it is coming from dead center. The "Out of Phase" tone should sound diffuse, wider, and lacking bass compared to the in-phase tone.
