About the Infinity Kappa 52.11i
Legendary sound
Legendary sound
Infinity's Kappa Series 52.11i 5-1/4" speakers continue in the tradition of this legendary line of speakers, offering rugged construction and impressive sound quality. Once installed, these speakes 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 system. The "edge-driven" design results in a larger tweeter that handles more power and delivers smooth response way down into midrange frequencies not covered by smaller "W"-shaped domes. You'll hear a more clearly defined soundstage where you can picture the placement of every instrument.
Infinity's UniPivot design allows you to aim each tweeter toward your ears, so you enjoy excellent stereo imaging even if the speakers are mounted way down low in your doors. Each tweeter also features a level control switch so you can boost 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 55 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: The formed glass fiber cone material is very light and extremely stiff, minimizing 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.
UniPivot Tweeter: The tweeter is angled and can be rotated about 315° after installation. This allows you to direct the tweeters toward the listeners, very useful for speakers mounted low in a door.
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 55 watts, they also list the recommended power range as 5-75 watts RMS. We've opted to list the more conservative 55 watt RMS figure on the specifications page.

Fantastic range, set crossovers at 80 to start with and then went ahead and dropped to near 50 and let it over lap with the Sub, seems to bring out more bass from the speakers and not rely on sub to produce the wider range and no distortion playing at 3/4 volume. Love these
