ML 280.3 Legend

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.

ML 1650.3 Legend

1. Neodymium magnet optimized with FEA simulations for real dynamics and utmost control.

2. Very low carbon content CNC machined plates, for maximum magnetic permeability

and low distortion at high power levels.

3. Aluminium covered pole for a linear impedance modulation and low distortion.

4. 36 mm CCAW double layer voice coil wound on a Polyamide former for exceptional power

handling and compression-free re production even in the most demanding musical passages.

5. Exponential V-cone® with optimized geometry for utmost linearity and dispersion at
mid frequency range.

6. “Boundary Free” IIR rubber surround, for better efficiency and wider mid-bass frequency.

7. Pressed-pulp cone with cotton fibres, combining stiffness and lightweight, to

achieve wide frequency response and limited break-ups at high frequency.

8. Three-spoke, very acoustically transparent anti-resonant aluminium alloy basket
featuring built-in venting holes.

9. CNC machined elegant diamond-cut basket edge featuring the Hertz logo.

10. Die-cast aluminium factory provided grille featuring diamond-cut aluminium Hertz logo.

MLCX 2 TW.3 Legend

1. Bi-amplification available, selectable through appropriate hi-current rating switch
with hi-current carrying capability.

2. “Mid-Contour” two-position control, for a linear mid-bass frequenc y response according
to the woofers position in the car and the listener’s favourite sound.

3. “Hi-Contour” two-position control, to select the tweeter hi-pass crossover point selection
according to the tweeter position/angle towards the listener.

4. “Mid-Contour” in conjunction with “Hi-Contour” provides the ability to use MLCX 2 T W.3
to build a two way system based on ML 1650.3 or ML 180 0.3 woofer together with
ML 280.3 tweeter.

5. Three-position switch for tweeter level adjustments in 2 dB steps, to fine-tune the
transducer’s emission.

6. “Hi-Boost” control, selectable through appropriate switch, to provide better linearity
of the tweeter emission above 10kHz when positioned not on axis to with the listener.

7. Extremely high quality bi-metallized 160V polyester film capacitors with ultra-low DF,
for maximum sound transparency and neat mid/hi-frequencies.

8. Air wound inductor s 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.

9. High power rating Wirewound resistors, to ensure per formance 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.
