Know before you buy
THX SELECT2 certification ensures that the speaker meets strict performance standards for output levels and sound quality in medium-sized rooms. It guarantees that the audio will perform as the director intended, providing a consistent, cinematic experience.
By placing the tweeter at the exact acoustic center of the woofer, the Uni-Q array acts as a single point source. This design helps sound disperse more evenly across the room, ensuring that everyone in the listening area hears the same high-quality audio regardless of where they are seated.
Yes, the grille is designed to be paintable, allowing you to blend the speaker seamlessly into your room's decor. The Ultra Thin Bezel ensures that once installed and painted, the speaker remains discreet and minimalist.
Absolutely. The Ci4100QL-THX is an excellent choice for a center channel speaker because its precise imaging and wide dispersion help anchor dialogue and sound effects directly to the screen.
While the speaker is designed for easy in-wall mounting, we recommend checking your local building codes and wall cavity depth. Using an appropriate enclosure or back box can help optimize the bass response and provide consistent sound performance.
You will need a mounting depth of approximately 3.15 inches (80mm). It is important to verify that your wall cavity has enough clearance to accommodate the speaker assembly and any necessary wiring.
