The company Infinity has shown the world how to use technology from different spectrums, for many purposes.

The company was started in 1986 in America and today, they are a part of the Harman International Industries.

Here’s how they revolutionize the industry.

Firstly, Infinity supplies speakers to an expansive range of markets:

  • Home use through their surround-sound home theatre systems
  • State-of-the-art units for home or office that are built into the wall
  • Marine use through their well-sealed speaker units
  • Car audio market through their subwoofers and amplifiers.

They're one of the primary suppliers for:

  • Hyundai
  • Kia
  • Mitsubishi
  • Chrysler

Secondly, Infinity’s founders and engineers have experimented with many new methods.

This led to amazing products to include in their portfolio:

  • They use neodymium magnets.These are much lighter than ordinary magnets, which means speakers aren’t as heavy anymore
  • The founders used weapons technology and applied it to speakers to invent the Servo-Static speaker.

These and other feats led to the development of a strong competitor in the audio manufacturing market.

Vehicle owners are bound to find a few options for their specific brand and model, among the various speakers Infinity manufactures.

Today Infinity should be one of your options when considering upgrading your vehicle’s sound equipment. 

They didn't make it into our list of the best car speakers of the year (check it here) as there are better choices for the top 10, but they're definitely a solid choice.

Infinity REF6522IX REVIEW

Even if you have to build a box, this template is included in your purchase.

An essential aspect of good sound is whether it can be projected from the correct angle.

These speakers utilize Infinity’s invention of UniPivot, which allows you to adjust the dome tweeters.

You can make sure they’re angled in the exact position that affords you clear sounds even when it’s playing at high volumes.

This means that no matter where your speakers are installed, you can aim the tweeters in your direction.

If you only have space where sounds may get muffled, you can still have the speakers set up so quality sound waves reach your ears.

The features of the tweeter further extend to its level control. Depending on your preferences when it comes to the brightness of music, you can set the tweeter to an acceptable level.

Bass blockers also help prevent distortion and improve sound quality.

You’re assured of using these speakers for a long time, thanks to sufficient protection via rubber surrounds in the woofer cone.

If something does go wrong, you’re covered by the 1-year warranty that comes standard.



This speaker has a remarkable frequency range, starting at 45 Hz and running through to an amazing 35 kHz.

This means most of the sounds you love to hear will clearly come through on these speakers.


  • Sensitivity: 93 dB
  • RMS: 90 watts
  • Peak Power: 2700 watts
  • Frequency Response: 45-35,000 Hz
  • 2way/3way/4way: 2-Way 

This range must be supported by quality components for the sounds to be as clear as they are vast.

The quality is tended to via:

Speaker terminals that are gold plated to improve the security of connections

Increased cone area


Infinity Kappa 60.11CS REVIEW

Distortion is kept to a minimum by the temperature controls on the voice coils

Apart from this, the speaker is protected by:

A vented magnet prevents overheating

The speaker frames are made from Injected Carbon Glass Matrix which prevents cracks from forming

Rubber speaker surrounds prevent damage from shock and vibrations



These 5.25 inch speakers belong to the Kappa Series, and although poor on bass, deliver loud and clear tones on the mid and high frequencies.

  • Sensitivity: 94 dB
  • RMS: 55 Watts
  • Peak Power: 165 Watts
  • Frequency Response: 55-25,000 Hz
  • 2way/3way/4way:  2-Way 

Firstly, you benefit because the engineers didn’t install the customary W-shaped dome, but instead an edge-driven one.

This enables the speaker to produce smooth high frequency sounds.

You can see the trouble they went to in order to perfect this when you look at the speaker’s frequency response.


 Infinity Kappa 52.11i Review

Infinity uses their UniPivot system in this speaker, which enables you to angle the tweeter towards you, no matter where the speaker is installed.

This enhances the quality of the high notes you hear.

For the car owners who love hearing—and feeling—bass sounds, Infinity uses a quality woofer.

The glass fiber unit keeps its shape throughout, so your bass tones are always clear.



The feedback on these speakers is nothing but positive.

Even though they don’t offer the most extensive frequency response range, the speakers emit powerful, clear sounds in the range they’re designed to.

They're a good budget choice for those who aren't too concerned about bass, and are looking for good sound quality.

  • Sensitivity: 92 dB
  • RMS: 35 Watts
  • Peak Power: 105 Watts
  • Frequency Response: 75-21,000 Hz
  • 2way/3way/4way: 2-Way

You can simply add a subwoofer if you’re in search of more extensive bass sounds.

Installing these speakers is easy, though some cars will require minor modifications.


Infinity 4002CFX review

If you don’t want to bring permanent change to your vehicle, you can simply modify the speaker holes.

After that, you should see they fit perfectly.

Thanks to the strong polypropylene used in the cone and the protective butyl rubber surrounds, you’ll enjoy long-term service from these excellent speakers.



Final thoughts

So, coming back to the original question: Are Infinity speakers any good? Yes they are

Are they worth the price tag? Yes indeed.

This means in each Infinity speaker you install, you’ll have the benefit of quality sound and durable parts.

They consistently create stunning looks for their speakers, so you’ll love how your car looks and sounds after installing Infinity speakers.
