Overview

The MLK 700.3 Legend car audio speakers system aims at offering a mid-high frequency range of excellence, to combine with a Legend woofer with a choice between ML 1650.3 and ML 1800.3 actively filtered in a multi-amplified configuration. MLK 700.3 Legend is composed of the ML 700.3 Legend Extended Midrange, the ML 280.3 Legend tweeter and the MLCX 2 TM.3 dedicated crossover that features the unique Mid-Countour control with its three-position selector, acting on the mid frequencies of the ML 700.3 Legend midrange by varying the cross-point with the tweeter to obtain the desired sound. The V-cone® exponential profile without the traditional dustcap gets close to the perfect one, generating exceptional dispersion: thanks to the synergistic action of these technological elements, ML700.3 Legend boasts outstanding high frequency extension making it possible to build purist two-way systems in combination with ML 1650.3 Legend or ML 1800.3 Legend. Thanks to this configuration, where there is only one cross-point, phase rotations are limited to the minimum, ensuring excellent soundstage and disarming timbre consistency. With the mid-high frequencies being handled by the ML700.3 Legend and the low ones by the ML1800.3 Legend, the whole audio range is reproduced with transducers built with the same materials and based on the same electro-acoustic structure; that doesn’t happen with woofer and tweeter, since due to its own nature the tweeter is different in materials and structure. The uniformity in materials and structures creates very high timbre consistency, so the speakers can “disappear” and leave room to emotions.

Features

ML280.3 Legend Tweeter
- Neodymium magnet optimised with FEA simulations of the magnetic flux for utmost control and fast response to the transients
- Extremely pure copper short circuit ring, for excellent very high frequency extension
- Die-cast aluminium face plate with profile optimised with FEA simulations to improve frequency response and dispersion
- Tetolon Fiber dome optimised with FEA simulations for lower distortion and improved dispersion in high frequency range
- Frame structure and rear load chamber both derived from a CNC machined solid aluminium block, to ensure mechanically inert response to resonances
- Rear chamber sized for only 900Hz Fs: low Fs ensures wide extension in low frequency range and low distortion also in the crossing section, allowing a decreased cut-off frequency
- 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
ML700.3 Legend Mid Range
- Neodymium magnet optimised with FEA simulations, for superior dynamics and control
- Very low carbon content CNC machined plates, for maximum magnetic permeability and low distortion at high power levels
- Extremely pure copper covered central pole and one-layer mobile coil, for a wider extension in the high frequency range
- Exponential V-cone® with optimised geometry for utmost linearity and dispersion
- CONEX spider with optimised profile, for maximum transparent acoustics at mid-high frequency
- Boundary Free rubber surround, for better efficiency and wider mid-bass frequency
- Pressed-pulp cone with cotton fibres, combining stiffness and lightweight, to achieve wide frequency response and limited break-ups at high frequency
- Junction point between cone and former with geometry optimised with FEA methods, allowing a more integral coupling, thus ensuring wider extension at high frequency
- Three-spoke, very acoustically transparent anti-resonant aluminium alloy basket featuring built-in venting holes
- CNC machined elegant diamond-cut basket edge featuring the Hertz logo
- Die-cast aluminium factory provided grille featuring diamond-cut aluminium Hertz logo
MLCX2TM.3 Legend Crossover
- Mid-Notch function, a sophisticated notch passive network featuring a three-position switch to select the amount of acoustic effect. It also provides the ability to linearise the midrange frequency response according to its position in the car and considering the woofer selected to complete the system low frequency range
- Three terminals for tweeter level adjustment in 2 dB steps, to fine-tune the transducer emission
- Extremely high quality 160V ultra-low DF polyester bi-metallised film capacitors, for maximum sound transparency and neat mid/hi-frequencies
- Air wound inductors built on pure copper-wire with up to 1mm diameter, for high saturation threshold of the magnetic flux and low losses on the woofer section where high transient currents are demanded
- High power rating Wirewound resistors, to ensure performance stability even at high operating temperature. The Wirewound construction grants low parasitic series inductance thus reducing losses at high frequencies, especially for resistors in series to the tweeter
