Abstract
L'invention se rapporte aux enceintes acoustiques asservies comportant une boîte fermée et plusieurs haut-parleurs. L'invention a pour objet une enceinte avec amplificateur dans laquelle les haut-parleurs forment deux groupes constituant en série les deux premières branches d'un montage en pont; les deux autres branches dudit montage en pont forment un diviseur de tension. Une boucle de contre-réaction est branchée au noeud des deux premières branches et une boucle de réaction est branchée au noeud des deux autres branches. L'invention s'applique notamment aux dispositifs électroacoustiques de reproduction sonore.
