Infinity Kappa 683XF 6"x8" / 5"x7" Coaxial Speakers

Kappa quality

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.

Plus One+ woofer technology

Kappa's glass fiber woofer will hold its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer either. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass to complement the superior high-frequency response.

Awesome power handling, no matter the system

These 3-ohm speakers boast ultra-high sensitivity so that you can power them with a factory radio or aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp. Either way, these speakers' low impedance safely takes advantage of every watt of power available for exceptional performance. Enjoy Kappa sound quality at any volume.

Grilles are not included; the factory grilles should be suitable for most applications.
