(54)	A method and a system to adjust the acoustical performance of a loudspeaker

(57) The invention relates to a method and a system for optimizing the performance of a loudspeaker system as perceived by user.
The physical part of the speaker system is adjustable which enables the speaker units to be placed in positions that imply maximal acoustical performance. This is obtained by combined means to: 1) bring the speaker in a specified position and 2) apply accordingly position dependant individual acoustical filters inserted in the signal path to each individual speaker.
