Le haut-parleur coaxial B&C Speakers 8CX21 est un 20cm (8") avec moteur de compression haute puissance et système magnétique ferrite.
B&C Speakers propose un filtre passif étudié pour un fonctionnement otpimal du 8CX21, le filtre 2 voies X0-1, fréquence de coupure à 2,0kHz.
Attention le filtre X0-1 est disponible en option seulement, il n'est pas fourni avec le haut-parleur.

Prix affiché en haut à droite pour un haut-parleur coaxial seul sans le filtre passif X0-1.
