Every sound speaker, from the smallest to the most powerful, has a permanent magnet. Located behind the center of the speaker cone, the magnet interacts with a changing magnetic field from an electrical coil. The pushing and pulling forces move the speaker cone rapidly in and out, producing sound. Speaker manufacturers use different kinds of magnets to suit speakers of different sizes and to achieve a range of tone qualities.
Due to the sizes of the magnet, there may be variations on pull strength. Please contact our customer service team for more information.
