Upgrade Your Vehicle With Confidence. This Is Built to Fit, Perform, and Last
Hertz MLK 700.3 LEGEND | Mille Legend Series 3" 2-Way Mid-High System
The Hertz MLK 700.3 Legend is a specialized two-way system designed to provide a mid-high frequency range of absolute excellence. By handling everything from 200 Hz up to 28 kHz, this kit is intended to be paired with a dedicated Mille Legend woofer (like the ML 1650.3) in a multi-amplified setup. This configuration minimizes phase rotations and ensures disarming timbre consistency, allowing the speakers to "disappear" and leave only the emotion of the music.
Product Highlights
-
V-cone® Exponential Profile: The ML 700.3 midrange utilizes a dustcap-free V-cone® for exceptional dispersion. This synergistic design allows for an outstanding high-frequency extension, making a purist two-way front stage possible.
-
ML 280.3 Legend Tweeter: This system features the reference-standard 35 mm (1.38 in.) Tetolon dome tweeter. It is engineered for maximum transparency and a very low resonant frequency, ensuring a seamless blend with the midrange driver.
-
Mid-Contour Control: The dedicated MLCX 2 TM.3 crossover features a unique three-position selector. This allows you to vary the cross-point between the midrange and tweeter to achieve the perfect sound balance for your specific vehicle.
-
Neodymium Magnetic Group: Both the midrange and tweeter utilize high-density Neodymium magnets. This provides a high-energy magnetic field for maximum control and dynamic response while keeping the mounting profile compact.
Key Features
-
Boundary Free Surround: The midrange driver employs a specialized surround geometry that increases the effective emission surface, allowing for higher SPL and improved low-mid extension without increasing the speaker's physical size.
-
Exceptional Timbre Consistency: Because the mid-high range is handled by drivers sharing the same materials and electro-acoustic structure, the transitions are nearly audible, resulting in a cohesive and realistic soundstage.
-
Pure Copper Voice Coil: Wound on a Polyamide former, the voice coil is designed for high power handling and thermal stability, ensuring the system remains clear during high-dynamic musical peaks.
-
Aluminum Die-Cast Basket: The anti-resonant basket features an open design to eliminate back-wave reflections, preserving the purity of the midrange frequencies.
