Hertz MP250D23 – 10″ SUBWOOFER 2+2 OHM

Outstanding performance in a compact size, this is the target of Mille Pro car audio subwoofers. The MP 250 D2.3 cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for Legend. The V-cone profile increases rigidity, allowing the cone to function like a piston. Surround materials consist of high-purity IIR-butyl rubber. Like the Legend ML2000.3 and ML2500.3, the Mille PRO subwoofers are built with Boundary Free Surround technology allowing for a greater emission surface with equal diameter, generating higher sound pressure. The 65-mm 4-layer voice coil is higher than 60 mm and wound in a TIL-P former, thus delivering high linear displacement.

Features

• Better thermal inertia to ensure low operating temperatures during musical transients.
• Thanks to a greater amount of iron in the pole the likelihood of magnetic saturation decreases exploiting the maximum flux density generated from the magnet.
• Possibility to install the subwoofer right on the box wall, taking full advantage of its minimal dimensions.

TECHNOLOGIES

V-CONE®
The exponential profile gets very close to the perfect one, providing exceptional dispersion.

eID (Elettromedia Identification)
The exclusive technology providing the traceability of the Mille.3 products from their birth on. Once the test phase has been passed, the code linked to destination country/market is applied. When purchasing the product, by scanning the code, the user can check through the web the information about the product and can log into the registration page.

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.
