Hertz Mille Legend ML 1650.3 - 16.5 cm Mid-Woofer for Precise Mid-Bass
The Hertz Mille Legend ML 1650.3 is a 6.5-inch (16.5 cm) mid-woofer for high-performance door installations. Featuring a neodymium motor, 36mm CCAW dual voice coil, and a stiff pulp cone with cotton fibers, it delivers controlled mid-bass and clean mids. The usable frequency range extends from 40 Hz to 6.5 kHz, with 93 dB efficiency and 4 Ohm impedance â ideal for high-quality 2-way front systems, whether passive or active via DSP. Available at Carhifi.shop.
Technical Highlights
For maximum control and low distortion, the ML 1650.3 utilizes an FEA-optimized neodymium motor, low-carbon CNC-machined steel plates, and aluminum-coated pole pieces for linear impedance control. The 36mm dual CCAW voice coil on a polyamide former offers high thermal stability. The Exponential V-cone geometry and "Boundary Free" IIR rubber surround improve efficiency and dispersion, while the three-spoke aluminum basket with ventilation ensures mechanical stability.

Installation & Compatibility
The ML 1650.3 fits into the common 165 mm class and is suitable for door and kick panel positions. With a 141 mm mounting hole and 69 mm mounting depth, it can be installed in many vehicles. Stable adapter rings and solid door insulation are recommended. Operation can be passive with high-quality crossovers or active via DSP; the wide bandwidth allows flexible crossover to the subwoofer and tweeter.
