About the Infinity Kappa 572.5cf
Premium materials distinguish the Infinity Kappa 572.5cf 5"x7"/6"x8" speakers from the rest of the pack. These Kappas feature a Ceramic Metal Matrix Diaphragm woofer and tweeter, formed by bonding an aluminum cone to two layers of ceramic. First used in Infinity's award-winning Prelude home speaker line, C.M.M.D. is an extremely rigid, heat-resistant material that reproduces music with remarkable accuracy.
The C.M.M.D. Plus One woofer cone incorporates a unique basket design and a hi-roll rubber surround to deliver robust low-end performance with minimal distortion. The angled Unipivot C.M.M.D. tweeter may be turned to create the best possible imaging. Customized, voice-matched crossovers (18 dB/octave, 3,500 Hz high-pass and low-pass) direct the right frequencies to the right drivers for superior efficiency.
With some of the highest power ratings in its class, you can be sure these speakers will play your tunes loud and long. Grilles are not included — use your factory grilles for installation.

Product Research
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 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. The positive woofer lead has a 0.205" female quick-slide and the negative woofer lead has a 0.110" female quick-slide. The positive tweeter lead has a 0.250" female quick-slide and the negative tweeter lead has a 0.187" female quick-slide. These quick-slides connect directly to the woofer and tweeter terminals on each speaker.
Crossover Dimensions: L=3.458", W=1.734", H=1.087"
