    • The sound reproduction system is of the kind which comprises electro-acoustic transducer means, and transducer drive means for driving the electro-acoustic transducer means in response to a plurality of channels of a sound recording. The electro-acoustic transducer means comprises sound emitters which are spaced-apart in use, the transducer drive means comprising filter means that has been designed and configured with the aim of reproducing at a listener location an approximation to the local sound field that would be present at the listener's ears in recording space, taking into account the characteristics and intended positioning of the sound emitters relative to the ears of the listener, and also taking into account the head related transfer functions of the listener. The invention concerns the fact that the electro-acoustic transducer means comprises at least one pair of sound emitters that are spaced from the interaural axis of the listener at the listener location and positioned substantially in a plane that includes said interaural axis and is inclined relative to a reference horizontal plane that also includes said interaural axis, the angle of inclination of said inclined plane relative to said horizontal plane being in the range 60° to 120°. The pair of transducers will usually be positioned higher than the head, and the preferred angle of inclination of said plane is in the range 75° to 105°.
