Hertz MPK 163.3 PRO
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
The Hertz MPK 163.3 Mille Pro is a premium 3-way component speaker system designed for audiophiles who want a "no-compromise" soundstage. By using a dedicated 3-inch midrange driver alongside the woofer and tweeter, this system provides superior vocal clarity and a more realistic, detailed separation of instruments than standard 2-way sets.
Key Features
-
Dedicated 3-Way Design: Includes the MP 165.3 woofer, MP 70.3 midrange, and MP 25.3 tweeter. This configuration allows each speaker to focus on a specific frequency range, resulting in less distortion and a much broader, more immersive soundstage.
-
V-Cone® & Boundary Free Surround: The woofer and midrange use a unique V-shaped cone for better off-axis dispersion, meaning the music sounds clear even if the speakers aren't pointed directly at you. The "Boundary Free" surround allows the cone to move more air, delivering deeper mid-bass from a 6.5-inch driver.
-
Tetolon Soft Dome Tweeter: The 1.14" tweeter is made from Tetolon (a silk/cotton blend) and features a "Center Tuning Duct" to lower its resonance frequency. This provides smooth, natural highs that avoid the "harshness" often found in metal-dome tweeters.
-
Customizable Crossovers: The included MPCX 3.3 crossovers use high-quality bi-metallized polyester film capacitors for transparent sound. They feature 2-position level switches for both the midrange and tweeter (0 / +2 dB), allowing you to fine-tune the output based on your car's acoustics.
