The present invention relates to a modular loudspeaker, primarily intended to be used as a studio monitor and comprising a broadband module for radiating a first frequency range with a lower limiting frequency sufficiently low to provide a fully acceptable reproduction in many situations and furthermore provided with a high frequency radiating unit (and possibly also a mid frequency radiating unit), the directional characteristics of which relative to the cabinet of the module can be controlled. The modular loudspeaker according to the invention furthermore comprises one or more low frequency module(s) for radiating a second frequency range which may at least partially overlap said first frequency range for either increasing the acoustical output at the lower end of the frequency range radiated by the broadband module or for extending the lower limiting frequency of the complete modular loudspeaker below the lower limiting frequency of the broadband module. The modular loudspeaker according to the invention is furthermore provided with means for transmission of information about the presence&#x2014;and number&#x2014;of low frequency modules applied in order to automatically change appropriate signal processing parameters in order to obtain a given target response of the complete modular loudspeaker.
