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.

  • Plus One C.M.M.D. woofer cone

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

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.

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.
