La série LVGC™ regroupe des haut-parleurs basse fréquences de forte puissance. Ils intègrent la technologie Vented Gap Cooling pour un meilleur refroidissement et une structure d’aimant améliorée
Symmetrical Field Geometry (SFG). Ceci permet d’optimiser la densité
de flux pour diminuer la distorsion harmonique du haut parleur. En évitant ainsi l’utilisation de métaux rares, ces haut-parleurs offrent des performances élevées pour un coût mesuré.
