Description
Hertz's 3" (8cm) midrange driver, the MILLE PRO MP 70.3, comes equipped with a powerful neodymium double magnet inside the coil, delivers gripping midrange tones and has powerful dynamics thanks to the 20mm coil. Special features include the V-cone® profile, which enables optimum lateral dispersion, and the Boundary Free Surround for an extension to the lower frequency range. Also noteworthy are the symmetry of the dual neodymium magnet structure and the Exponential V cone, which offer a wide frequency response and maximum linearity.
