Mille Pro MPX 690.3 by Hertz
The Hertz Mille Pro MPX 690.3 is a 6 x 9 inch Speaker Set with a 3-way design. It combines a 28 mm Tetolon Tweeter with a neodymium magnet and faceplate profile for side radiation with a separately integrated 20 mm neodymium Tetolon fiber dome super tweeter. The woofer uses a 38 mm voice coil made of pure copper on a polyamide coil carrier, a pressed cellulose membrane with cotton fibers, a large rubber surround, and a high-density flux ferrite magnet. An aerodynamic basket made of aluminum alloy, a vibration-damping rubber magnet cover, and a tweeter front plate with geometry optimized through FEM simulations complete the construction, along with an exceptional cooling system. The performance and basic data include 130 W RMS, 260 W peak, 4 Ohms, a frequency response of 30 to 24 kHz, and Xmech ±8 mm. Additional specifications: bass magnet 107 x 45 x 20 mm and weight per speaker 2.28 kg.
