Product Details
- Infinity Kappa 503CFKappa Series 5-1/4 component speaker system Infinity designed and built their Kappa Series for audiophile tastes. This Kappa 503CF 5-1/4 component speaker system benefits from a refined design, Infinity's proprietary technology, and premium materials to deliver uncompromised audio quality. Plus, Infinity has added convenient features for getting just the right sound for your ride. Infinity employs an edge-driven design in their silk dome tweeters for a smoother, more open response and minimal distortion at high volume. With a frequency response that peaks at 40,000 Hz, you'll have what you need to hear a new level of detail in the car. Dial in your sound even more and adjust the tweeter level using the control button on the separate crossovers.
