Magnetic drivers use rare earth neodymium magnets, which provide a vastly stronger magnetic field than conventional magnets, while using fewer and smaller ones.
High Sensitivity: The higher field strength of these remarkable magnets means that your amplifier does not have to work nearly as hard to deliver a satisfactory listening experience.
Plays Louder and Lower: Since the magnetic field is so much stronger, it becomes possible to open up the space between the front and rear magnet arrays, giving the diaphragm more room to move.
