Hertz MLK 165.3 component speakers (165 mm).

Hertz MLK 165.3 (MILLE series) 2-Way Component Speakers 6.5" (165 mm).

The MLK 165.3 Legend car audio speakers system is composed of the ML 28.3 Legend tweeter and the ML 165.3 Legend woofer with the MLCX 165.3 dedicated crossover. 
The woofer originates from the ML 1650.3 Legend, inheriting all its technologies such as the Boundary Free Surround, the V-cone profile Pressed-pulp cone with cotton fibres, the six spoke aluminium basket with vented holes; however, it has been designed employing a high density ferrite magnet assembly, characterising its emission in the mid frequency range. 
The woofer originates from the ML 1650.3 Legend, inheriting all its technologies such as the “Boundary Free Surround”, the V-cone® profile Pressed-pulp cone with cotton fibres, the three spoke aluminium basket with vented holes; however, it has been designed employing a high density ferrite magnet assembly, characterising its emission in the mid frequency range. 
The ML 28.3 Legend tweeter mounts the same Neodymium magnet assembly as the ML 280.3 Legend’s and features all the optimizations made with FEA methods on the dome profile, and that it shares with its “older brother”, except for the most esoteric features such as the die-cast aluminium faceplate, the CNC machined body made from solid aluminium block and the copper short circuit ring. 
Like MLCX 2 TW.3, also the MLCX 165.3 crossover features the “Hi-Contour” control to adjust the ML 28.3 tweeter cut-off frequency and so the cross-point with the ML 165.3 woofer, according to the position of the two speakers in the car. Through the tweeter three position level control, with 2 dB step attenuation, the level for a correct timbre balance can be fine-tuned according to one’s own tastes.
