Infinity first developed the Ceramic-Metal Matrix Diaphragm (C.M.M.D.) for home speaker systems — sandwiching an aluminum cone between two layers of ceramic to create a rugged, extremely musical driver. The 693.3i 6"x9" 3-way speaker uses C.M.M.D. design in both its oversized Plus One woofer and 1" dome tweeter for exceptional full-range performance. The EMIT supertweeter adds impressively-detailed high-frequency response.

The 693.3i also includes an outboard 2-way crossover for a seamless transition from woofer to tweeter. A cast-polymer basket and foamed rubber surround eliminate unwanted resonances, adding to speaker accuracy. 3-year warranty.

  • oversized Ceramic Metal Matrix Diaphragm woofer with foamed rubber surround (Plus One woofer is 30% larger than standard 6"x9" cones)
  • 1" C.M.M.D. dome tweeter
  • 1-1/8" metallic planar EMIT supertweeter
  • frequency response 35-22,000 Hz
  • recommended power range 2-110 watts RMS
  • peak power handling 330 watts

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 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"
