Hertz MP 70.3 PRO | Mille Pro 3" Midrange Speakers
The Hertz MP 70.3 PRO is a high-end 3-inch (70 mm) midrange driver designed to be the heart of a sophisticated 3-way component system. Featuring a Neodymium double magnet inside the voice coil, this speaker is engineered to produce an enthralling and detailed midrange. It is the perfect acoustic bridge between the powerful low-end of Mille Pro woofers and the refined highs of Mille Pro tweeters, creating a seamless and lifelike soundstage.
Product Highlights
-
Exceptional Midrange Detail: The double Neodymium magnet structure provides a highly symmetrical magnetic field, ensuring maximum vocal clarity and instrumental precision.
-
V-cone® Technology: This proprietary exponential profile optimizes off-axis dispersion, meaning the speakers sound balanced and clear even when they aren't pointed directly at your ears.
-
Boundary Free Surround: Allows for a larger cone surface area within the same footprint, providing better efficiency and a wider extension into lower frequencies.
-
High Efficiency: With a sensitivity of 88 dB, these drivers are optimized to deliver high-output performance when paired with quality aftermarket amplification.
Key Features
-
Pressed-Pulp Cone with Cotton Fibers: Combines the natural, warm sound of paper with the stiffness of cotton fibers to eliminate unwanted resonances and distortion.
-
20 mm (0.8") Voice Coil: Maximizes dynamic response and provides excellent thermal management for consistent performance during long listening sessions.
-
Compact Mounting Profile: With a mounting depth of only 1.73 inches, these drivers are easier to integrate into custom A-pillars or factory dash locations.
-
Reliable Construction: Built with premium materials to ensure the "Hertz Sound Experience" remains consistent throughout the life of your vehicle.
