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 Harman International Industries.

Here’s how they revolutionized 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.
