Infinity has blended a bundle of audio innovations into a smooth-sounding 4" package! The Kappa 42.5i features Ceramic Metal Matrix Diaphragm (C.M.M.D.) cones, which are constructed by sandwiching aluminum between layers of ceramic to form a lightweight, durable driver that is extremely musical.

The oversized Plus One C.M.M.D. woofer cone delivers accurate low-frequency performance with minimal distortion. A cast-polymer basket and hi-roll rubber surround help to eliminate unwanted resonances. The C.M.M.D. balanced dome tweeter reproduces high notes in rich, lifelike detail.

An outboard 2-way crossover network (computer-optimized for the 42.5i) routes signals to the appropriate drivers - you'll enjoy component system sound quality from these easy-to-install coaxials.
