Mille Pro MP 70.3 by Hertz
Hertz's 3-inch midrange driver, the Mille Pro MP 70.3, is equipped with a powerful neodymium dual magnet inside the voice coil, delivering captivating midrange tones and offering strong dynamics thanks to the 20-mm coil. Special features include the V-cone® profile, which enables optimal lateral dispersion, and the Boundary Free Surround for extending into the lower frequency range. Also notable are the symmetry of the dual neodymium magnet structure and the Exponential V cone, which provide a wide frequency response and highest linearity.
