Terra Tech: Let's Talk Magnets

Terra Acoustics Jeep Front SoundStage Speaker Upgrade for Jeep Wrangler and Jeep Gladiator

Let's take a moment and talk about magnets and how they relate to speaker design.

A magnet's job is to keep the electro-acoustical components of the speaker cool and under precise control during musical playback. Using high-density Neodymium motor structures allows us to keep the speakers cool given their location atop the dash coupled with controlling the heat generated by the voice coil’s movement.

Our motors are commensurate with the intent of the driver. IE, we don't need a large, heavy neodymium structure given the small cone diameter + location + intent of the midrange driver. You can see the difference in the image above between our driver (left) and the factory driver (right).

Marketing departments around the world loved using big ferrite magnets in the 90's as it was something tangible and "look, it's bigger so it must be better"...

Magnet size is simply a reflection of the intent of the driver.
