High Fidelity Kappa Series

The 2-ohm nominal impedance of the Infinity Kappa 50.11cs 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.

amazing

I bought these speakers and the 6 1/2 version, while ive only installed the 6 1/2"s in a previous vehicle, powered by a kenwood 4ch amp pushing 85w @ 2ohm, they sounded incredible, super crisp and clear. i am now installing the 5 1/4 set into my current vehicle and have purchased the current model of the kenwood amp that powered the 6 1/2" set, which will put out 100w @ 2ohm. due to the 5 1/4" being a small speaker size i imagine the very low end will suffer, which is why i am also going to be running an 8" sub to complete the setup.

Crisp clean and LOUD!

I got these to replace my Kappa 6x8's that were discontinued years ago. The old Kappa's were amazing and I only replaced them after a careless mechanic smashed one of my tweeters. It turned out to be a good thing because I am seriously impressed by these new Kappa 5.25's. They are loud and crisp with tremendous frequency response and sensitivity. I'm running these with an audiophile quality Pioneer deck and an old school MTX Elite 1000.4 4 channel amp. I highly recommend these speakers. Please amplify to reach their full potential!
