PROBLEM TO BE SOLVED: To solve the problem wherein sound pressure of high frequency falls and the high frequency must be boosted by a circuit to compensate the fall of the high frequency while two speakers are arranged at an angle of 180 degrees in the case of obtaining a wide sound field. SOLUTION: This speaker consists of a speaker unit for an L channel and an R channel whose oscillating axes are arranged to mutually become an angle of approximately 180 degrees and in which reproduction sound pressure of high frequency is higher than middle and low frequency and an enclosure which stores the speaker unit for the L channel and the R channel.
