lnfinity Kappa Series loudspeakers embody technological breakthroughs that make them, quite simply best in class. lf you are looking for sound quality that rivals the best home audio systems, then Kappa is the ideal choice.Plus 0ne woofer cones patent pending technology delivers a cone with more surface area than competing models of the same size. The result is increased bass output and higher efficiency.Edge-driven MMD dome midrange 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.Woven glass fiber woofer cone material is extremely stiff, minimizing cone flex which yields very low distortion and improved clarity, an lnfinity trademark.SLl high-output design. Conventional 4-ohm speakers do not leverage all of the power available from today's car audio amplifiers and high-powered head units. This topology extracts every last watt from the amplifier source, increasing overall system output and efficiency.Computer-optimized voice-matched outboard passive crossovers - Each Kappa multi-element 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.To ensure response clear out to 25kHz, both three-way multi-elements use lnfinity's famous EMlT tweeter.Adjustable tweeter level-Each Kappa multi-element features a user adjustable tweeter level control. 0n the two-way models, simply rotate the tweeter to add or subtract 3dB output. 0n the three-way models, it is the simple push of a button right on the tweeter faceplate.

Buyer's feedback: - * You might need an amp for those lows. ...
Do you have an amped system or at the very least an aftermarket head unit? If so, these are the replacement speakers for you.

Don't have either of those things?

Well, you should probably go with the Reference series... they do a better job when they have to run off your stock head unit.

I installed these Kappas with a stock head unit, and the head unit couldn't power them sufficiently for the bass to be clear on the higher settings.

These speakers are higher end for Infinity, and I really recommend an amp or a 50W X 4 head unit. Otherwise, you're might be a tad disappointed.

The speakers are EXTRAORDINARILY clear. Seriously, all you need is a little extra power from an amp or aftermarket head unit, and you'll love it. You might not even need to get a sub, depending on how hard you like to bump.
