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.

Our take on the Infinity Kappa 693.11i

by John Pollard

Legendary sound

Infinity's Kappa Series 693.11i 6"x9" speakers continue in the tradition of this legendary line of speakers, offering rugged construction and impressive sound quality. Once installed, these speakers will bring out every nuance and detail in your favorite music tracks, making time spent in your car seem more like a concert than a commute.

Large soft dome tweeters

If you're looking for natural-sounding high frequencies, Infinity uses edge-driven 1" soft dome tweeters in this speaker. The "edge-driven" design creates a larger tweeter that handles more power and delivers smooth response way down into midrange frequencies not covered by smaller "W"-shaped domes. Infinity adds 1" super tweeters for extended high-frequency detail, producing a more clearly defined soundstage where you can picture the placement of every instrument. A level control switch allows you to adjust the brightness to your taste.

Glass fiber woofer with Plus One+ technology

If you like bass, the Kappa glass fiber woofer holds its shape when the power's cranked up, so you still get punchy and defined bass. Glass fiber weighs less than traditional materials, so you don't need a ton of power to drive this woofer. Infinity's Plus One+ woofer technology extends the cone right up to the edge of the basket, giving you more surface area than with most comparable speakers. A bigger cone means more bass to complement the superior high-frequency response.

Great for any system

These 2-ohm speakers are sensitive enough that you can power them with an aftermarket stereo, but you'll get your best results feeding them plenty of power from an outboard amp — up to 110 watts RMS. Grilles are included.

Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and a significant increase in efficiency.

Formed Glass Fiber Woofer Cones: This formed glass fiber material is very light and extremely stiff, minimizing cone flex. This results in very low distortion and improved clarity.

iCGM frames: The Kappa series speaker baskets are made of composite Injected Carbon Glass Matrix (iCGM). iCGM is lighter and stronger than stamped steel; it retains its shape, even when mounted on uneven surfaces (common in car mounting locations), plus offers exceptional damping of any resonances.

Edge Driven Dome Tweeters: Each speaker has a 1" Edge-driven textile soft dome tweeter. An edge-driven tweeter has better dispersion characteristics and allows for a lower crossover frequency than typical tweeters of the same size, which improves imaging. The result is improved vocals and musical clarity. The tweeter also has an adjustable output level, +0 dB (flat) and +3 dB.

Super Tweeter: The Kappa 693.11 adds a 1/2" super tweeter to reinforce the high frequencies and keep pace with the larger cone of the 6" x 9" woofer.

High-Output Design: The high output 2-ohm voice coil design compensates for the high in-line resistance of small gauge factory wiring and extracts every watt from factory receivers, increasing overall system output and efficiency (relative to 4 ohm speakers). The speaker's 2.0-ohm impedance combined with the impedance of your speaker wire provides a true 4-ohm load to your connected headunit or amplifier. The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers, designed to power a 2-ohm load.

Terminals: The input terminals are gold-plated set screws that will accept up to 12 gauge bare wire.

Power Handling: Although Infinity lists the RMS power handling as 110 watts, they also list the recommended power range as 5-200 watts RMS. We've opted to list the more conservative 110 watt RMS figure on the specifications page.
