Review: Très bon upgrade pour un système audio d’origine J’ai installé ces enceintes dans ma BMW 335i E92 pour remplacer celles d’origine, et la différence est clairement audible. Le son est plus propre, avec des aigus bien définis et des basses correctes pour des haut-parleurs de 10 cm. La puissance est suffisante pour une utilisation quotidienne (trajets, musique, podcasts), même sans ampli. La sensibilité de 90 dB permet d’avoir un bon volume sans pousser à fond . Installation assez simple, surtout si vous avez déjà les emplacements adaptés. Le design est sobre et la qualité de fabrication inspire confiance (on sent que c’est du JBL). Petit point négatif : les basses restent limitées, ce qui est normal vu la taille (10 cm). Si vous cherchez un son très puissant avec grosses basses, il faudra ajouter un caisson.
Review: Suenan muy bien los recomiendo
