Abstract: A method of configuring an array of speaker elements is disclosed. The method computes a sound pressure level at various points in the venue and that is evaluated by various objective functions. The configuration of the array is changed, for example by the orientation or position of the speakers and the sound field is recalculated. The process is then iterated until an acceptable configuration is found. The real physical array of speakers is then configured in that manner. The method also provides a 3D plot of the sound pressure level displayed against frequency and position in the venue.

Abstract: A method of configuring an array of speaker elements is disclosed. The method computes a sound that pressure level at various points in the venue and is evaluated by various objective functions. The configuration of a candidate array is changed, for example by the orientation or position of the speakers and the sound field is recalculated. The process is then iterated until an acceptable configuration is found. The real physical array of speakers is then configured in that manner. The method also provides a 3D plot of the sound pressure level displayed against freguency and position in the venue.

Abstract: A driver for a loudspeaker is mounted in an opening in an acoustic surface, for example a horn, and has a piston shaped to conform to the shape of the acoustic surface. This ensures that the presence of the driver does not disrupt the acoustic properties of the desired shape of the acoustic surface. Preferably the piston is made of closed cell foam and is attached directly to the coil holder of the driver unit.
