Infinity's Kappa speakers set a new standard in car audio. Our patented Plus One™ woofers deliver tight, robust bass and highly detailed, musical performance. Edge-driven textile dome tweeters with oversized voice coils deliver silky-smooth highs with increased thermal power handling for the high-volume enthusiast. An optional midrange speaker with bandpass crossover is available to upgrade two-way component systems to three-way systems for higher performance where a three-way system is desired or fits into factory locations. Each model is voiced using audiophile-grade inductors and capacitors, resulting in detail and precision unmatched by other brands in its class. And Kappa's 2-ohm design extracts every watt of power from the amp or head unit for outstanding performance. Kappa is the performance of all car speakers..PZA MORE SPECS
