1. A neodymium magnet or NIB magnet is a powerful magnet made of a combination of neodymium, iron, and boron (Nd₂Fe1₄B).
2. Due to new environmental rules in Europe, SEAS can no longer copper-plate the back plate of the Excel woofers. These woofers will be switched over to a rubber boot, like the Nextel speakers.
