About the Infinity Kappa 63XF
Kappa quality
Kappa quality
Infinity designed and built their Kappa Series for audiophile tastes. These Kappa 63XF 6-1/2" 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 fibre woofer will hold its shape when the power's cranked up, so you still get punchy and defined bass. Glass fibre 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.

Features
Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
Edge Driven Dome Tweeters: Each speaker has an edge-driven silk dome tweeter. Edge-driven tweeters have better dispersion characteristics and allow for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity. The tweeter also has an output level switch; choose +0 dB (flat) or -3 dB.
UniPivot Tweeter: The tweeter is angled and can be rotated about 315° after installation. This allows you to direct the tweeters toward the listeners, very useful for speakers mounted low in a door.
High-Output Design: The high output 3Ω 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 4Ω speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 3Ω load.
Terminals: The input terminals are set screws that will accept up to 12 gauge bare wire.
Mounting Applications: These speakers are marketed as 6½"; they will fit in many standard 6½" speaker openings (just over 5" diameter), but do not use the standard 6½" speaker bolt pattern. In order to install them in standard 6½" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6½" mounting holes and the Ford non-symmetric four hole pattern, as well as other non-standard patterns. When using the brackets the depth becomes 1.892" and the mounting height becomes 1.068".

I love these so much! I previously had 4 (Kicker 46CSC674) with slightly less power handling than the Kappa 63XF's. 5 Channel amp with these running 75 watts RMS x4. The Infinity Kappas are way louder and have much more clarity at higher volume. (Also more expensive but WORTH IT!)
