ML 2500.3 LEGEND 250 (10) mm (in.) | Subwoofers | 1400 W | 4 Ohm

Los aficionados a la música que asisten a conciertos en vivo saben bien las emociones que las frecuencias sin distorsión baja sin compresión dinámica puede despertar. Por esta razón, la HertzAudioVideo R & D creó el subwoofer de audio del coche ML 2500.3 Legend. Durante la larga fase de desarrollo, los diseñadores se fijaron un solo objetivo ambicioso: transferir las emociones de una actuación en vivo al entorno del automóvil. Gracias a un diseño completamente renovado, los subwoofers de automóvil ML2000.3 tienen un tamaño extremadamente compacto y están optimizados para jugar en cajas con cajas reducidas. Esta elección de diseño combina dos requisitos difíciles de alcanzar hasta ahora: rendimiento de referencia y facilidad de instalación.

Die-cast aluminium optional grille featuring diamond-cut aluminium Hertz logo.

ML 2500.3 LEGEND

Full metal sturdy structure composed by a solid cast aluminium ring and a steel mesh black grille featuring an elegant diamond-cut Hertz Logo
Mounting screws totally hidden for a superior integration within the car cabin.

ML 2500.3 LEGEND

1. Extraordinary large neodymium magnet, optimized with FEA simulations, to ensure magnetic field stability even under high excursion.
2. Very low carbon content CNC machined plates, for maximum magnetic permeability and low distortion at high power levels.
3. Voice coil internal magnet with high size / performance ratio, for maximum efficiency.
4. CCAW, 100 mm (4”) voice coil, capable of handling 1400 W musical power, keeping the working temperature very low, reducing dynamic compression to the minimum.
5. Voice coil wound with In/Out method, for even cooling of the different coil layers.
6. Voice coil wound on TIL former: this material made from fibreglass combines the heat dissipation properties of aluminium with the stiffness of Polyamide composites, for a no-compromise acoustic performance.
7. Central pole featuring “Aluminium Shorting Ring”, for minimum distortion and maximum extension at low frequency.
8. “Boundary Free” IIR rubber surround, for higher SPL performance than other subwoofers with same external diameter.
9. Exponential V-cone® with optimized geometry for high cone stiffness and strong resistance to deformation even at maximum excursions.
10. Mineral-injected paper cone, for superior rigidity and damping.
11. Very acoustically transparent anti-resonant aluminium alloy basket featuring six-spoke self-standing structure and built-in venting holes underneath the spider.
12. CNC machined elegant diamond-cut basket edge featuring the Hertz logo.
13. Ergonomic, ultra-compact design, with array of electro-acoustic parameters optimized for sealed box application with 17 – 25 lt volume.

ML 2500.3 LEGEND

The V-CONE® profile prevents the cone from deforming during
its course, ensuring that the “piston” works in a correct position,
maximizing the production of acoustic pressure.

ML 2500.3 LEGEND
Boundary Free Surround

This technology provides the ability to achieve wider emission surface of the cone compared to speakers with same diameter; that way, the cone manages to move a bigger mass of air, so it produces more acoustic pressure. This special surround is built from highly pure IIR butyl rubber, ensuring extraordinary thermal and mechanical linearity.
