Infinity has been revolutionizing the industry with its products for quite some time now. 

Today, we’re looking at the Infinity Kappa speaker system alongside two other Infinity products.

The Reference series from Infinity features some of the best speaker systems out there. This product features detailed audio with extremely loud sound. You’ll find zero distortion in the music coming out of these speakers. 

Quick Summary of the Main Product

With Glass-fiber woofer cones and textile dome tweeters, the Infinity Kappa coaxial speaker system is sure to provide some of the best and detailed audio you’ll ever experience. 

The frequency response of these speakers is extremely wide. This means that the Infinity car speaker system is able to capture frequencies that normally would not be caught by lesser speakers. 

Not only is the audio extremely detailed but you’ll find that there is no distortion in the audio either, even at higher volumes. 

Features and Benefits

Wide Frequency Response 

The frequency response of a speaker or sound system refers to the frequency it’s able to emit. It’s expressed as a range and of course, the bigger that range is, the more detailed the sound will be. 

Glass-Fiber Woofer Cones

The glass-fiber woofer cones not only make these speakers much lighter than its competitors, but it also ensures that the bass is punchy and impactful. 

Textile Dome Tweeters 

Textile dome tweeters of these speakers are responsible for frequencies on the higher end. We’re pleased to say that this 6.5-inch system produces highs that are bright and easily distinguishable from the rest of the audio. 

Pros and Cons

The customer reviews for the Infinity Kappa are extremely positive with 82% of the reviews having 5-star ratings. 

People love how easy they are to install while others love what a great replacement they are for factory speakers.

Buyer’s Guide

2-Way or 3-Way? 

3-way speakers are much more detailed than 2-way speakers since they have a separate component that handles the mid-range frequencies. 

While 3-way speakers are better than 2-way speakers in almost every case when it comes to sound performance, they are also much more expensive. 

RMS Power Handling 

The RMS power handling of a speaker refers to how much power it can handle without blowing out over a certain period of time. 

This is the value you should be looking at when determining which speaker would be most suitable for your car. 

In order to find out what RMS power handling would be most appropriate for you, you’ll need to check what the power of your stereo setup or amplifier in your car is. 

Sound Quality

In order to determine whether a speaker actually sounds good, you need to observe whether or not you can clearly hear the highs and lows during music playback or not. 

A great speaker does a good job of distinguishing the high and low frequencies, so you can hear them distinctly simultaneously. 

Wrapping Things Up

This brings us to the end of our review for Infinity speakers. Infinity is a brand that you really can’t go wrong with. 

Every product of theirs is high-quality both in terms of sound as well as build. Furthermore, their products are very reasonably priced.
