Proper placement and connection are crucial for optimal sound performance. The CS-9040 is designed to be the central component of your home theater system, primarily handling dialogue and central sound effects.
3.1 Posizionamento
Position the center channel speaker directly above or below the center of your television screen. Ensure it is placed on a stable, flat surface such as a media console, shelf, or stand. The integrated rubber feet help prevent movement and protect surfaces. Avoid placing objects directly in front of the speaker grille to maintain clear sound projection.
