ML 28.3 Legend

1. Double Neodymium magnet optimized with FEA simulations, for maximum field

symmetry and exceptional transfer efficiency.

2. Tetolon Fiber dome optimized with FEA simulations, for excellent dynamics and angle dispersion.

3. Larger rear chamber, to reduce Fs from 1000Hz to 900Hz.

4. Natural fibre non-woven sound-absorption material, for better damping and more natural

acoustic emission.

ML 165.3 Legend

1. CCAW double-layer 36 mm voice coil on Kapton former, for exceptional power handling and

no-compromise dynamics.

Exponential V-cone® with optimized geometry for better dispersion and higher SPL performance.

2.

3. “Boundary Free” IIR rubber surround, for higher efficiency.

4. Cotton-injected paper cone for stiffness, lightweight and dynamics.

5. Three-spoke, anti-resonant aluminium alloy basket featuring built-in venting holes.

6. Highly acoustic transparent basket design

MLCX 165.3 Legend

1. “Hi-Contour” two-position control, to select the tweeter hi-pass crossover point according

to the tweeter position/angle towards the listener.

2. Three terminals for tweeter level adjustment in 2 dB steps, to fine-tune the transducer’s
emission.

3. Extremely high quality bi-metallized 160V polyester film capacitors with ultra-low DF,

for maximum sound transparency and neat mid/hi-frequencies.

4. Air wound built on pure copper-wire 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.

5. 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.
