In an audio system, cyanoacrylate adhesive can reliably hold neodymium magnets to a stator for a planar magnetic transducer when the transducer generates high output. In one implementation, the planar magnetic transducer can include multiple neodymium magnets aligned in rows on top of a stator. Each neodymium magnet may be aligned with another neodymium magnet, and each pair of neodymium magnets can be separated by a gap. The transducer can have spacers to fill each gap and separate each pair of neodymium magnets. Cyanoacrylate adhesive can bond the neodymium magnets to the stator and bond each spacer between each pair of neodymium magnets.
