High Fidelity Kappa Series

The 2-ohm nominal impedance of the Infinity Kappa 52.11I coaxial speakers allows compensation for any added resistance in thin factory-installed speaker wiring and provides more output than factory speakers in its class. The high sensitivity of the Kappa Series makes it ideal for upgrading a factory-installed system’s existing speakers with very noticeable fidelity improvements. The beautiful chrome inserts on the grille match modern interiors, and there are no visible mounting screws. With a modern look, articulate highs and strong lows, the Kappa series speakers are perfect for any factory or aftermarket sound system. Pick yours up today at SonicElectronix.com!

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.
