Modular loudspeaker

A broadband module system for use in a modular loudspeaker, said system comprising:

• a broadband module for the radiation of acoustical energy over a first frequency range;
• at least one low frequency module for radiation of acoustical energy over a second frequency range, which may at least partially overlap said first frequency range;
• at least one controllable pre-processing means for pre-processing of audio signals provided from an audio source and for distribution of said pre-processed audio signals between said broadband module and said at least one low frequency module;
• control information providing means for providing and transferring control information between said at least one low frequency module and said at least one controllable pre-processing means, for indicating the presence and number of said at least one low frequency module;
• whereby said pre-processing means, due to said control information, can sense the presence and number of said at least one low frequency module and thereby carry out appropriate changes of a set of signal processing parameters in order to obtain a given one of a set of predetermined target responses for the complete modular loudspeaker;
• said broadband module system comprising a cabinet with a front and at least two sound radiating units, wherein a directional characteristic relative to said cabinet of at least one of said sound radiating units can be controlled;
• and
• further comprising an input terminal for receiving an audio signal, said audio signal being provided to controllable pre-processing parameter adjusting means for controlling various signal processing parameters of the broadband module and providing first and second output signals, wherein the first of said output signals, is coupled to said at least two sound radiating units via a cross-over network and a plurality of power amplifiers, and wherein the second of said signal output signals is accessible from outside said broadband module via an output terminal, and wherein said broadband module is further provided with means for controlling said parameter adjustment means upon reception of external control information provided to said control means via a corresponding input means.
