ML 2500.3 LEGEND

Subwoofers

Miłośnicy muzyki, którzy uczęszczają na koncerty na żywo, dobrze znają emocje, które mogą wzbudzać niskie, niezdeformowane częstotliwości bez dynamicznej kompresji. Dlatego dział rozwoju firmy HertzAudioVideo opracował subwoofer samochodowy, ML 2500.3 Legend. Podczas długiej fazy projektowania, inżynierowie wyznaczyli sobie ambitny cel: przeniesienie emocji na żywo do wnętrza samochodu. Dzięki całkowicie nowej konstrukcji, subwoofery samochodowe ML 2500.3 mają niezwykle kompaktowy rozmiar i są zoptymalizowane do odtwarzania dźwięku w obudowach o małych wymiarach. Referencyjna jakość dźwięku i łatwość instalacji była trudna do osiągnięcia aż do teraz.

Features

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.

Technologies

  • V-CONE®

    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.
  • 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.
