One of the largest advantages associated with neodymium magnets is that they are relatively lightweight compared to other types of magnets used in woofers, such as iron-ferrite magnets. Sound systems that employ neodymium woofers are significantly lighter than sound systems that use other types of woofers.
Neodymium magnets are some of the most powerful magnets on Earth. This type of magnet is much stronger than the standard iron-ferrite magnet used in woofers. As a result, woofers can be created smaller yet offer the same performance values as larger woofers.
Despite the rarity of neodymium, woofers that feature neodymium magnets are not linked with much higher initial purchase costs than traditional iron-ferrite magnet woofers. Depending on size and the manufacturer, neodymium woofers can cost anywhere from a few dollars to a few thousand dollars.
