Abstract
Cette invention permet d'améliorer sensiblement le rendu sonore de toute chaîne stéréophonique haute fidélité en augmentant sa clarté de reproduction et en compensant sa faiblesse en extrême grave. Elle comprend un module électronique composé de filtres actifs 1, d'un amplificateur de puissance 2 et d'une enceinte acoustique supplémentaire 3. La partie grave de l'information issue du préamplificateur 4 est aiguillée vers l'amplificateur de puissance 2 et ensuite vers ce caisson de graves 3. L'amplificateur traditionnel 5 n'a donc plus qu'à reproduire le registre médium-aigu par l'intermédiaire des enceintes acoustiques déjà possédées 6 et 7. L'invention peut être incorporée dans tout système stéréophonique existant avec un minimum de modifications.
