A method carried out at a processing entity is provided. The method comprises determining, for each loudspeaker of an acoustic system comprising multiple loudspeakers, sound pressure level (SPL) data and total harmonic distortion (THD) data over different frequencies and different amplifier gain values associated with different SPLs. The method further comprises determining, for each loudspeaker based on the THD and the SPL data, a loudspeaker performance profile forming a plurality of loudspeaker performance profiles; and providing the plurality of loudspeaker performance profiles for an adaptation of a sound field generated by the acoustic system.
