Correct
Ces 2 haut-parleur produisent un son de qualité. Si c'est ce que vous recherchez je vous les conseille. Attention néanmoins, ce sont des hp 3 watt, et ils ne produisent pas un sont très fort. Prenez-le pour faire des bruits de robot, des animations sympas, ils conviendront surement. Mais si vous voulez faire des enceintes par exemple, il n'y aura pas assez de son.
