About the Infinity Kappa 572.3cf
The Infinity Kappa 572.3cf 5"x7"/6"x8" speaker employs proprietary Ceramic-Metal Matrix Diaphragm (C.M.M.D.) design in both its oversized Plus One woofer and swiveling dome tweeter. First developed for Infinity's award-winning Prelude home speakers, C.M.M.D.s are formed by sandwiching an aluminum cone between two layers of ceramic, creating an extremely musical driver that's virtually indestructible.
Infinity adds a cast-polymer basket and foamed rubber surround to this winning formula, minimizing unwanted resonances. A compact outboard 2-way crossover (designed for the 572.3cf) contributes to the exceptional sound quality. Grilles are not included. (Factory grilles are appropriate for most installations.) 3-year warranty.
Details:- Ceramic Metal Matrix Diaphragm woofer with foamed rubber surround — oversized Plus One woofer is 30% larger than standard 5"x7" cones

Features
Ceramic Metal Matrix Diaphragm (C.M.M.D.): Infinity's C.M.M.D. technology delivers accurate performance with dramatically reduced distortion for incredibly lifelike sound. Additionally, the C.M.M.D. drivers can withstand extreme temperatures, moisture, humidity and sunlight.
C.M.M.D. Plus One Woofer Cones: These speakers use cones approximately 30% larger than other speakers of the same size. This is accomplished by using a new basket design and hi-roll surround. The Plus One design offers greater bass output and a significant increase in efficiency. In addition, the C.M.M.D. cones virtually eliminate coloration due to cone flexing, resulting in less distortion and superior accuracy.
Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.
UniPivot C.M.M.D. Dome Tweeters: Each speaker has a 1" C.M.M.D. dome tweeter that offers superior stiffness and damping compared to traditional metal domes. The UniPivot tweeter is angled (non-adjustable) and may be turned up to 355 degrees for optimum imaging and in-car frequency response. It is not made to turn 360 degrees. If the tweeter is turned 360 degrees or more, it will be damaged.
2-Way Crossovers: These speakers include computer-optimized, voice-matched crossovers. Each crossover features an 18dB/octave, 3.5kHz high-pass network for the tweeter and an 18dB/octave, 3.5kHz low-pass network for the woofer.
Crossover Input/Output Connections: Each crossover has an 11" input lead terminated with bare wire and two 18" output leads, one for the woofer and one for the tweeter, terminated with female quick-slides.
Crossover Dimensions: L=3.458", W=1.734", H=1.087"
Adapter Rings: The supplied adapter rings allow you to top mount the speaker in a 6"x8" opening. The adapter ring adds 0.116" to the mounting height of the speaker, while reducing the mounting depth by the same amount. When using the adapter ring, the speaker has the following dimensions:
6"x8":
Vehicle Fit:
- Depth as top: 2.218"
- Mounting height: 0.738"
- Flange height: 0.414"
Basket Dimensions:
- Major apex of oval: 7.098"
- Minor apex of oval: 4.878"
- Frame width: 5.703"
- Frame length: 8.118"
Bolt Pattern:
- Number of holes: 6
- Diagonal 1: 8.221"
- Diagonal 2: 8.221"
- Minor axis 1: 4.761"
- Minor axis 2: 5.094"
