The KEF Ci100.2QR from the Soundlight Series is the perfect fusion of minimalist design and exceptional sound performance. Designed to blend seamlessly with your home’s decor, these speakers are as compact as halogen light fixtures, making them nearly invisible once installed. However, don’t let their size fool you—the Ci100.2QR delivers impressive audio thanks to KEF’s patented Uni-Q driver array, providing exceptionally wide sound dispersion for an immersive listening experience in any room.
