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 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.

1. Neodymium magnet optimized with FEA simulations of the magnetic flux for utmost control and fast response to the transients.
2. Extremely pure copper short circuit ring, for excellent very high frequency extension.
3. Die-cast aluminium face plate with profile optimized with FEA simulations to improve frequency response and dispersion.
4. Tetolon Fiber dome optimized with FEA simulations for lower distortion and improved dispersion in high frequency range.
5. Frame structure and rear load chamber both derived from a CNC machined solid aluminium block, to ensure mechanically inert response to resonances.
6. Rear chamber sized for only 900 Hz Fs: low Fs ensures wide extension in low frequency range and low distortion also in the crossing section, allowing a decreased cut-off frequency.
7. High-density damping material underneath the dome, low-density absorbing material in the rear chamber, providing fluid acoustic emission and high damping in the low frequency response.
