PROBLEM TO BE SOLVED: To solve a problem of a conventional speaker system that has lost a stereophonic image because a direct sound from a speaker unit is reflected in a front glass pane when the speaker unit is mounted on a dashboard of an automobile. SOLUTION: The speaker system comprises a 1st speaker unit that reproduces an (L+R) signal, a 2nd speaker unit that is placed at an angle of 45 degrees to the left with respect to the 1st speaker unit and reproduces an (L-R) signal, a 3rd speaker unit that is placed at an angle of 45 degrees to the right with respect to the 1st speaker unit and reproduces an (L-R) signal, a 1st reflection wall that is nearly placed orthogonally to the 1st speaker unit, a 2nd reflection wall that is nearly placed orthogonally to the 2nd speaker unit, and a reflection reduction member that is placed on the 1st and 2nd reflection walls to reduce a reflection sound due to the reflection walls.
