A true high-fidelity 5-1/4" (130mm) coaxial speaker for your car.
The Infinity® Kappa® Series 52.11i two-way coaxial speakers have features that no other company’s speakers can match. They feature proprietary Injected Carbon Glass Matrix (iCGM) frames and patented formed-glass-fiber Plus One® (U.S. patent no. 7,548,631) woofer cones. Each speaker’s coaxially mounted UniPivot™ (U.S. patent number 6,002,780) tweeter is a soft-dome, edge-driven fabric diaphragm for improved power handling and wide high-frequency dispersion. So even though the Infinity Kappa 52.11i coaxial speakers may be small – only 5-1/4 inches (130 millimeters) – they deliver big, strong sound.

25 – 165 watts suggested amplifier power range
Infinity engineers designed the Kappa 52.11i coaxial speaker to produce impressive, precise sound from a head-unit or amplifier capable of delivering up to 165 watts of power. This makes the Kappa 52.11i an ideal coaxial-speaker upgrade for systems powered with head-unit or factory amplifier power. They also handle the power from aftermarket amplifiers that are part of very high-fidelity aftermarket upgrades. Remember, great power-handling specifications increase reliability over the lifetime of the speaker, and that means that you’ll be enjoying the Kappa Series for many musical years.



Injected Carbon Glass Matrix (iCGM) frames
Kappa automotive speakers benefit from light and strong composite Injected Carbon Glass Matrix (iCGM) frames. Kappa Series speakers resist the environmental extremes of the car. They offer superior rigidity, even when mounted on uneven surfaces (common in car mounting locations), and exceptional damping of any resonances.



Vented motor assembly
The Infinity Kappa 52.11i coaxial speakers feature a vented motor assembly to let the voice coil breathe. It reduces the probability of power compression with systems playing loud over a long period of time. It means a more efficient use of amplifier power so that all the power delivered to the woofer is directed to the voice coil and not wasted as residual heat.



Plus One woofer-cone technology
The Plus One cone on the Kappa series increases the overall speaker-cone area in comparison to others in its class. With an effective increase in cone area, the speaker radiates more air. Also, the carbon-injected cone material produces a lighter and stiffer cone. The result is a better low-frequency response and a greater ability to generate those important, almost tangible musical notes that people often associate with a larger speaker size.



Edge-driven, soft-dome fabric tweeter
The 1-inch (25.4-millimeter) soft-dome, edge-driven fabric tweeter design in the Infinity Kappa tweeter increases power handling while reducing high-frequency distortion. An edge-driven tweeter also has better dispersion characteristics and allows for a lower crossover frequency than comparable tweeters of its size, which improves imaging. The result is improved vocals and clarity in music. There’s no sense in having a speaker play loud if it doesn’t sound clean, too.



2-ohm nominal impedance
The 2-ohm nominal impedance of the Infinity Kappa 52.11i coaxial speakers allows compensation for any added resistance in thin factory-installed speaker wiring and provides increased output when compared to factory speakers or others in its class.



Ultrahigh-frequency response (up to 25kHz)
A wide frequency response that extends to 25kHz helps compensate for speaker placement variations in a car and human hearing deficiencies in the high-frequency spectrum above 15kHz. The result is that the Infinity Kappa 52.11i coaxial speakers deliver more of the full-range frequency response that you associate with great sound.



Ultrahigh sensitivity (94dB@2.83V/1m)
High sensitivity allows a wider range of power to have positive results without overdriving the audio system. With a sensitivity of 94 decibels at 2.83 volts/1 meter, the Infinity Kappa 52.11i coaxial speakers achieve excellent volume and musicality with as little as 5 watts RMS. This means better performance overall with very moderate power, whether the speaker’s using a dedicated amplifier or not. The high sensitivity of the Kappa Series makes it ideal for upgrading a factory system’s existing speakers with very noticeable fidelity improvements.



UniPivot coaxial tweeter
The innovative UniPivot™ (U.S. patent no. 6,002,780) feature on the Kappa Series 52.11i coaxial speakers allows you to aim the tweeter at the listening location for better stereo imaging and high-frequency response at the listener’s ear. It offers even greater flexibility for off-axis mounting locations common in lower doors or kick-panel locations.



High-quality passive crossover components
The passive filter components in the crossover network of the Infinity Kappa 52.11i coaxial speakers use only the best parts, including air-core inductors, low-hysteresis polypropylene capacitors and high-quality resistors. We have engineered them to require minimal parts, which also means minimizing phase-related anomalies. Overall, the combination results in each Kappa Series speaker having a unique filter arrangement with minimal but very effective parts to achieve true high fidelity, clarity and performance.



Protective, soft, rubber-finish grilles
The Infinity Kappa 52.11i coaxial speakers feature a handsome appearance, with a soft rubber finish like the finish on many mobile-phone protective cases or the back of home A/V remotes. The beautiful chrome inserts on the grille match modern interiors, and there are no visible mounting screws. The grilles are an ideal complement to any installation location where the speakers are not already installed behind a factory-speaker location.



Gold-plated, screw-type speaker terminals
Gold resists corrosion from normal automotive use, which makes it ideal for the connections on Infinity Kappa speakers. By adding screw terminals, the speakers ensure tight, long-term connections that also allow reliable connection with the large-gauge speaker cables common in high-end aftermarket installations.
