Hertz ML 1600 6" 250W Mille Series 2-Way Active Component Speakers

Hertz Mille Series 6.5″ 2-Way Active Component System REN® Neodymium, CCAW Voice Coil, 93dB Sensitivity.

Product Overview

The Hertz ML 1600 is a 6.5-inch (165mm) 2-way active component speaker system from Hertz's acclaimed Mille Series one of the most technically refined component speaker lines available in the car audio market. Designed for audiophile-grade active crossover setups, the ML 1600 pairs Hertz's engineering expertise in motor design, cone materials, and chassis construction to deliver exceptional midrange clarity, low-distortion bass, and seamless integration with a separate tweeter in a 2-way configuration.

At the heart of the ML 1600 woofer is a REN® Neodymium ring magnet, an ultra-light pressed paper cone enriched with cotton fibres and water-repellent impregnants, and a 36mm CCAW (Copper Clad Aluminium Wire) double layer voice coil wound on a Kapton® former for linear impedance and accurate motor control. The absence of a traditional dust cap replaced by an exponential profile optimises dispersion characteristics, while the anti-resonant aluminium alloy basket and Nomex® spider with integrated lead wires reflect the uncompromising build quality of the Mille Series.

Features & Benefits

• REN® Neodymium ring magnet: Hertz's proprietary REN® neodymium motor provides exceptional magnetic flux density in a compact, lightweight form factor enabling higher sensitivity and more controlled cone motion than conventional ferrite motor assemblies
• Ultra-light cotton-enriched pressed paper cone: The cotton fibre-reinforced pressed pulp cone combines rigidity with low mass for accurate, detailed midrange reproduction and reduced colouration
• No dust cap exponential profile dispersion: The absence of a traditional dust cap and the exponential cone profile generates an outstanding dispersion pattern for wide, even sound coverage in the vehicle cabin
• 36mm CCAW double layer voice coil on Kapton® former: The CCAW winding reduces voice coil mass while maintaining conductivity, while the copper sleeve on the central pole piece provides linear impedance for accurate, fatigue-free reproduction
• Anti-resonant aluminium alloy basket: The uniquely designed low-incidence spoke basket minimises resistance to rear wave emissions, reducing coloration from internal standing waves
• Nomex® spider with integrated lead wires: Nomex® provides long-term fatigue resistance and consistent suspension behaviour across the full excursion range, with integrated lead wires for a clean, reliable connection
• Butyl rubber magnet cover: Protects the neodymium magnet assembly and contributes to the reduction of unwanted resonances and residual vibration at the motor
• 93dB sensitivity: High sensitivity rating means the ML 1600 performs at its best with quality headunit and amplifier combinations in an active crossover configuration, delivering excellent dynamic range from moderate power levels

Frequently Asked Questions

What power amplifier is recommended for the ML 1600?

The ML 1600 handles 125W RMS continuously with a 93dB sensitivity rating. A high-quality amplifier delivering 75–125W RMS per channel at 4 ohms will drive these speakers to their full potential. For active configurations, separate amplifier channels are required for woofer and tweeter.

Can the ML 1600 be used in a passive crossover configuration?

The ML 1600 is described as part of a 2-way active component system. For passive crossover use, confirm the compatible Hertz Mille Series passive crossover network that suits the ML 1600 before purchasing.

What are the Thiele-Small parameters used for?

The Thiele-Small parameters (Fs, Vas, Qts, Xmax etc.) allow experienced installers and audio engineers to model the optimal enclosure type, volume, and crossover settings for this driver. These figures are particularly useful for custom enclosure design and DSP-based active crossover setup.

What mounting diameter is required for the ML 1600?

The ML 1600 requires a 144mm mounting hole diameter and a minimum mounting depth clearance of 75mm. Confirm these dimensions suit your vehicle's door or custom enclosure before purchasing.

What is the return policy for this product?

Return eligibility is subject to the retailer's policy. Always verify mounting dimensions in your specific vehicle before purchasing. Contact the seller if you're unsure prior to purchase.
