## Description

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: Clear and detailed sound! - Absolutely fantastic clarity and efficiency! I will say they do take I bit of EQing to sound just right but I couldn't ask for a better speaker for the job! 10/10 would buy these over and over again! Fits perfectly in my 2003 dodge Durango!
Review: Amazing speakers - Fits in the majority of cars on the market and they sound good with decent bass. It would be better if you the equivalent component speakers if you can even though it’s a higher price. But with the pivot tweeter on these guys, it works good enough. The sound could be more right in your face with the component speaker equivalent though. I have these paired with the JBL Basshub and Infinity Kappa 6x8 for the front speakers. It sounds really good.

## 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.

### ⭐⭐⭐⭐⭐ Amazing speakers

### ⭐⭐⭐⭐⭐ Great coaxial speakers
*by S***N on June 28, 2023*

I'm sending about 60watt RMS to each of these. They sound very loud and clear. Bass is very punchy and an improvement over the Kickers it replaced. Being able to orient the tweeter direction is a very nice feature. Definitely recommend.
