Car Speakers
Infinity designed and built their Kappa Series for audiophile tastes. These Kappa 683XF 6"x8" car speakers benefit 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. Edge-driven silk dome tweeters. Infinity employs an edge-driven design in their silk dome tweeters for a smoother, more open response and minimal distortion at high volume. The UniPivot angled tweeter design means you can rotate each tweeter up to 270° to aim them toward your ears, so you'll enjoy excellent stereo imaging even if the speakers are mounted way down low in your doors. Each tweeter also features a level control button so you can adjust the brightness to your taste. (Priced as Pair)
High-Output Design: The high output 3? voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4? speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 3? load.
Terminals: The input terminals are set screws that will accept up to 12 gauge bare wire.
