Hertz MPK 165P.3 PRO
Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
Hertz MPK 165P.3 PRO | Mille Pro Series 6.5" 2-Way Component System
The Hertz MPK 165P.3 PRO is a high-energy component system engineered for enthusiasts who demand a powerful mid-low range and a detailed, balanced soundstage. This "P" (Power) version is specifically forged to deliver the solid sound of authentic mid-bass, making it the ideal setup for high-dynamic systems. With a unique 3-Ohm impedance, it is designed to extract maximum performance from your amplification, creating a professional-grade acoustic experience.
Product Highlights
-
V-cone® Technology: The MP 165P.3 woofer features an exponential profile that provides exceptional dispersion. This ensures that even when mounted in factory door locations, the mid-high frequencies reach the listener with incredible clarity and natural timbre.
-
MP 25.3 Tetolon® Tweeter: This 29 mm (1.14 in.) soft fiber dome tweeter is designed for a low resonant frequency and extended high-end. It features a center tuning duct for optimized air exchange, ensuring smooth and detailed high-frequency reproduction.
-
High-Current Crossover: The MPCX 2P.3 crossover uses a 1 mm diameter copper inductor wire specifically to filter the woofer's high impulse currents. This dedicated filter ensures a seamless transition between the drivers for a linear and powerful output.
-
3-Ohm Voice Coil: Unlike standard 4-Ohm speakers, the MPK 165P.3 uses a lower impedance design to draw more power from your amplifier, resulting in increased output and better control over the mid-bass "punch."
Key Features
-
Boundary Free Surround: The woofer utilizes a specialized surround geometry that increases the cone's effective surface area, allowing for higher SPL (Sound Pressure Level) while maintaining total control during high excursion.
-
Tweeter Level Control: The crossover features a two-position level control (0 / +2.5 dB). This allows you to adapt the system's brightness based on the tweeter's mounting position or your personal listening preference.
-
Audiophile-Grade Components: The tweeter network is built with 160V bi-metallized polyester film capacitors and air coil inductors, minimizing signal loss and ensuring maximum transparency in the high-frequency range.
-
Optimized Cooling: The woofer's motor assembly is designed for high thermal stability, allowing the system to handle 115W of continuous RMS power while remaining cool and undistorted during long listening sessions.
