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 speaks 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. 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. 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. 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.
