## Description

Kappa Car Speakers. Make Your Drive Come Alive: Infinity Kappa Series speakers, available in all standard sizes, are designed to bring a new standard of excellence in car audio to virtually any vehicle. Kappa’s Plus One™ fiberglass woofers deliver high-output, deep and robust bass. The high-resolution 3/4" edge-driven textile dome tweeters deliver soaring highs up to 40kHz. 2" and 3" midranges are available to upgrade two-way component systems into three-way. The compact 3" midrange speakers also offer a perfect plug-and-play solution with low frequency response to 300Hz, and high sensitivity.

Review: Very Satisfied - Awesome Sound from a stock stereo even. Would sound even better with an amp to push these. They can certainly handle it. Which is why I bought them. I intend to install an amp. They are a little pricey especially if you only intend to use with a stock radio. These want to be pushed. Very clear sound and clean bass. Tweeters are also clean and clear. Very satisfied.
Review: These speakers are legit. - Kappa's are always good. They really sing with 100 watts. Clean and loud. 5 stars for infinity and 5 stars for the seller's sale price being better than crutchfield and my local shop.

## Features

- Kappa edge-driven silk dome tweeters equipped with oversized voice coils deliver silky smooth highs with impressive thermal power handling and 40kHz high resolution.
- Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition, delivering increased low-frequency output and higher efficiency. Hearing is believing.
- The push-button on the angled tweeter allows tweeter output level control of 0dB or -3dB to optimize system linearity based on installation location.
- For 5-1/4", 6-1/2" and 6" x 8" coaxial models, the tweeters are angled and can be rotated 270° after installation on most models. This gives you imaging options and the ability to elevate the soundstage on low mounted speakers.
- Kappa 2-way component system crossovers are compact and equipped with 2-way and 3-way selections to accommodate a 2" or 3" midrange upgrade. The optional 2" or 3" midrange includes a bandpass crossover to upgrade a two-way system into a three-way system with perfect tonal balance.

## Questions & Answers

**Q: Are these 110wrms per woofer&tweeter pair or 110wrms for the whole set, which would only be 55wrms per woofer&tweeter pair?**
A: Thanks for your question. Power Handling: 110Wrms per pair.
World Wide Stereo is 43 years old and a proud authorized Infinity dealer.

**Q: I want to run this component set in a 3 way configuration 2" mid. How much power should I run to them with an amp? Can it be run bridged since 3ohm?**
A: Our Infinity Kappa 603CF can be used as a full-range 2-way speaker system or a 3-way; it engages more electronics in the crossover. The woofer continues to act as a woofer, and the tweeter acts as a tweeter, but you now have the opportunity to add the 2 inches to act as a midrange.

We would recommend the designated amps for our Kappa series, which are Infinity Kappa 4 and 5. While the nominal impedance is 3.5 ohms, this is the average impedance of the system. Because the woofer and tweeter are not reproducing the same frequency, they are not overlapping, so the nominal impedance of each speaker stays the same.

**Q: What type of alterations are needed for the tweeters in a 2022 hyundai kona sel?**
A: Our Infinity Kappa 603CF will need some brackets when installing the speakers in your 2022 Hyundai Kona.

**Q: Will this fit a VW Touareg  2016?**
A: Our Infinity Kappa 603CF will not fit in your 2016 Volkswagen Touareg.

### ⭐⭐⭐⭐⭐ Great speakers
*by B***R on August 2, 2022*

It's been only 2 days since the install, but having tweeters mounted at/near ear level is great and better than the OE stock. I don't know/think these Kappas are as good as my Morel 602 Ultra MKII (amplified), but the SQ is really good just with the head unit. Definitely would recommend on a budget or wanting to upgrade beyond OE.
