Infinity Kappa 63.5i
6-1/2"/6-3/4" 3-way car speakers
Our take on the Infinity Kappa 63.5i by Crutchfield's Todd Cabell
Infinity's Ceramic Metal Matrix Diaphragm speaker cones, first used on their award-winning Prelude home speakers, are constructed by bonding an aluminum cone to two layers of ceramic to form a rugged, lightweight, and extraordinarily accurate driver. Now you can put C.M.M.D. technology in your car's 6-1/2" speaker openings with the 3-way 63.5i Kappa speakers.
The 63.5i's C.M.M.D. Plus One woofer cone is approximately 30% larger than other 6-1/2" speakers, thanks to a unique basket design and hi-roll rubber surround that generate impressive bass while minimizing unwanted resonances. Bright highs flow from the C.M.M.D. dome tweeter, while a metallic planar EMIT supertweeter ensures that you don't miss any piece of high-frequency information.
Voice-matched 2-way crossovers (customized for the 63.5i) ensure that frequencies are routed to the appropriate driver, so the woofer and tweeter operate as efficiently as possible. These speakers include adapters for 6-3/4" openings.

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.
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.
EMIT Super Tweeters: Each speaker uses a 1-1/8" metallic planar EMIT tweeter for bright, well defined high frequency reproduction.
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"
Adapter Rings: These speakers come with three different mounting adapters. The adapters allow the speakers to be installed in a 6-1/2" opening, a 6-3/4" opening, or an oversized 6-3/4" GM/Chrysler opening.
