## Description

Kappa quality: 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.

## Features

- Kappa edge-driven silk dome tweeters equipped with oversized voice coils deliver silky smooth highs with impressive thermal power handling and 40kHz high resolution.
- Infinity’s glassfiber woofer cones are lighter and stiffer with more cone-area than the competition, delivering increased low-frequency output and higher efficiency. Hearing is believing.
- The push-button on the angled tweeter allows tweeter output level control of 0dB or -3dB to optimize system linearity based on installation location.
- For 5-1/4", 6-1/2" and 6" x 8" coaxial models, the tweeters are angled and can be rotated 270° after installation on most models. This gives you imaging options and the ability to elevate the soundstage on low mounted speakers.
- Kappa 2-way component system crossovers are compact and equipped with 2-way and 3-way selections to accommodate a 2" or 3" midrange upgrade. The optional 2" or 3" midrange includes a bandpass crossover to upgrade a two-way system into a three-way system with perfect tonal balance.
