Neodymium magnet optimized 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 optimized with FEA simulations to improve frequency response and dispersion
Tetolon Fiber dome optimized 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 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
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
Neodymium magnet optimized with FEA simulations for real dynamics and utmost control
Very low carbon content CNC machined plates, for maximum magnetic permeability and low distortion at high power levels
Aluminium covered pole for a linear impedance modulation and low distortion
36 mm CCAW double layer voice coil wound on a Polyamide former for exceptional power handling and compression-free reproduction even in the most demanding musical passages
Exponential V-cone® with optimized geometry for utmost linearity and dispersion at mid-frequency range
“Boundary Free” IIR 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
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
Bi-amplification available, selectable through appropriate hi-current rating switch with hi-current carrying capability
“Mid-Contour” two-position control, for a linear mid-bass frequency response according to the woofers position in the car and the listener’s favourite sound
“Hi-Contour” two-position control, to select the tweeter hi-pass crossover point selection according to the tweeter position/angle towards the listener
“Mid-Contour” in conjunction with “Hi-Contour” provides the ability to use MLCX 2 TW.3 to build a two-way system based on ML 1650.3 or ML 1800.3 woofer together with ML 280.3 tweeter
Three-position switch for tweeter level adjustments in 2 dB steps, to fine-tune the transducer’s emission
“Hi-Boost” control, selectable through an appropriate switch, to provide better linearity of the tweeter emission above 10kHz when positioned not on axis to with the listener
Extremely high quality bi-metallized 160V polyester film capacitors with ultra-low DF, 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 build construction grants low parasitic series inductance thus reducing losses at high frequencies, especially for resistors in series to the tweeter
