They are one of the primary suppliers for:

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. Here are some notes on their different products.

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.

2. Infinity Kappa 60.11CS

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.

Specifications:

  • 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

EDITOR'S RATING:

Increased cone area

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

Pros

Cons

3. Infinity Kappa 52.11i

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.

Specifications:

  • 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.

EDITOR'S RATING:

 Infinity Kappa 52.11i Review

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

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.

Pros

Cons

4.  Infinity 4002CFX

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.

Infinity 4002CFX review

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

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.
