Hertz Uno Series X 130 5inch 160W Coaxial Speaker

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.

Features:

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