System for selecting a loudspeaker based on its low frequency rendering

A system for selecting a loudspeaker based on its low frequency rendering, comprising:

• a plurality of synthesizers for generating a corresponding plurality of signals;
• a plurality of filters for band-pass filtering the plurality of generated signals, each filter filtering the signal generated by one of the plurality of synthesizers, each filter being configured for performing the band-pass filtering in a dedicated frequency band;
• a plurality of loudspeakers for playing the plurality of filtered signals, each loudspeaker playing the signal filtered by one of the plurality of filters;
• and
• a channel configurator for selecting one among the plurality of loudspeakers based on a reference amplitude spectrum of a model signal and a low frequency response of each one of the plurality of loudspeakers, the low frequency response for one of the plurality of loudspeakers representing a maximum amplitude of a given signal played by the one of the plurality of loudspeakers for frequencies included in a low frequency range
• wherein the selection consists in selecting the loudspeaker among the plurality of loudspeakers providing the best low frequency response for a range of low frequencies of the reference amplitude spectrum of the model signal, and
• wherein a simulated average amplitude for the range of low frequencies is calculated for each loudspeaker based on the reference amplitude spectrum of the model signal for the range of low frequencies and the low frequency response of each loudspeaker, and the selected loudspeaker provides the highest simulated average amplitude for the range of low frequencies.
