ML 2500.3 LEGEND

Subwoofers

Musik-Fans, die Live-Konzerte besuchen, kennen die Gefühle, die niedrige unverzerrte Frequenzen ohne Dynamikkompression wecken können. Aus diesem Grund hat das Hertz Entwicklungsteam den ML 2000.3 Legend und den ML 2500.3 Legend entworfen, die beiden Referenz Subwoofer der Mille.3 Legend Serie. Während der langen Entwicklungsphase haben die Entwickler sich selbst nur ein einziges ambitioniertes Ziel gesetzt: Den Transfer der Emotionen einer Live Performance in die Umgebung des Fahrzeugs. Dank der kompletten Runderneuerung des Designs haben die Subwoofer eine extrem kompakte Größe und sind dafür optimiert, in verkleinerten Gehäusen zu spielen. Diese Wahl des Designs kombiniert zwei Anforderungen, die bisher kaum erreicht werden konnten: Performance und ein einfacher Einbau.

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.
