Enceinte Active bi-amplifiée 2 voies, ultra-compacte, contrôlée par DSP. H.P. 4“ + Tweeter 0,75“, montage coaxial, 50 W, Charge AIREA = 50W.
Enceintes actives, intégrant amplification numérique, et technologie DSP. L’amplificateur peut être considéré comme double, car il gère séparément les fréquences aigues et le reste de la bande audio, tel un système 2 voies. En combinaison avec les DSP multicanaux, ce montage garanti le meilleur rendu audio possible, une dynamique accrue , une réponse en fréquence parfaite et une protection optimale des composants sensibles. Trois modèles d’enceintes large bande et trois caissons de basses sont disponibles.
