METHOD AND SYSTEM FOR MANAGING THE LOW FREQUENCY CONTENT IN A LOUDSPEAKER SYSTEM

The present invention relates to a method for managing the low frequency content obtained by a loudspeaker system comprising a plurality of loudspeaker devices, such as a surround sound loudspeaker system, wherein each individual loudspeaker device has a known response as a function of frequency under anechoic conditions comprising a phase response, the method comprising the steps of providing a plurality of loudspeaker devices (1, 2, 3, 4) and for each of said plurality of loudspeaker devices (1, 2, 3, 4) providing the corresponding phase response as a function of frequency obtained under anechoic conditions and for each of the individual loudspeaker devices (1, 2, 3, 4) inserting a filter device (5, 6, 7, 8) in the signal chain to the corresponding loudspeaker device (1, 2, 3, 4), where the individual filter device (5, 6, 7, 8) is configured such that the resulting phase response of each individual loudspeaker device (1, 2, 3, 4) under anechoic conditions is substantially the same for all of the loudspeaker devices (1, 2, 3, 4). The invention further relates to a loudspeaker system implementing the method of the invention.
