Product Description

Infinity built their Kappa Series speakers with improved technology and high-end materials to provide you with outstanding sound reproduction. The low-impedance design makes these speakers very efficient — you can even power them with your factory radio and get great results.

The Kappa 50.9cs component speaker system features 5-1/4" woofers with responsive woven glass-fiber cones that won't flex during a hard workout. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils add a little more punch to the bass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.

Infinity uses the same textile dome tweeters found in many of their popular home speakers with this Kappa system, so you'll hear the music the way it was recorded with minimal coloration or distortion. The tweeters handle down to 2,500 Hz, almost an octave below the tweeters in many systems, so you'll hear more definition and detail, no matter where you sit. Infinity includes mounting hardware to install the tweeters in custom or factory openings.

Features

Specifications

Plus One woofer cones ~- This patent pending technology deliver a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency.

Edge-driven UHF dome tweeter ~- These are not commonly used W-domes, but fully edge driven domes like those found in fine home audio loudspeakers. This much larger voice coil increases power handling and provides better sonic integration with the mid-woofer. This brand new Infinity tweeter delivers flawless output to 35kHz, ensuring reproduction of every last detail.

Woven glass fiber woofer cone ~material is extremely stiff, minimizing cone flex which yeilds very low distortion and improved clarity, an Infinity trademark.

True Four Ohms~— All Kappa speakers feature two ohm voice coils. Original factory-installed speaker wiring in many cars is 18-22 gauge. This wire, and heating in the voice coil when power is applied, increase the impedance “seen” by the amplifier or head unit. The impedance of Kappa Speakers has been adjusted to compensate for this increase and can be safely driven by any head unit.

Computer-optimized voice-matched outboard passive crossovers ~- Each Kappa multielement and component system features an outboard crossover that has been voice-matched using audiophile grade air core inductors and polypropylene capacitors. The result is flawless performance with incredible detail and accuracy.

Adjustable tweeter level~-Each Kappa component system features a user adjustable tweeter level control on the passive crossover.
