Hertz MP250D43 – 10″ Car Subwoofer 4+4 Ohm

The Mille Pro MP250D43 subwoofer offers outstanding performance in a compact design, utilizing the same pressed-pulp cone construction with mineral injection as the Legend series. The V-cone profile adds rigidity, allowing piston-like cone movement, and the high-purity IIR-butyl rubber surround enhances durability. Boundary Free Surround technology provides a larger emission surface, increasing sound pressure. Its 65-mm, 4-layer voice coil wound on TIL-P material supports high linear displacement and heat dissipation. The dual 4 Ω voice coil configuration enhances versatility for various amplifier setups.

The innovative air cooling system eliminates the need for a center hole, offering:

Improved thermal inertia for low temperatures during intense playback
Maximized magnetic field for higher flux density
Easy installation directly on the box wall with a damping rubber disk for air exchange
Solid push terminals with anti-short circuit covers accept up to 8 AWG cables, ensuring ultra-low wiring resistance in low impedance setups.

Features

Compact design for sealed box enclosures starting from 17 liters.
65 mm, 4-layer CCAW voice coil, handling 1200 W peak power with 4 Ω + 4 Ω DVC configuration.
TIL-P voice coil material with venting holes for efficient cooling and dynamic sound.
V-cone® design for high stiffness and minimal deformation at maximum excursion.
Boundary Free IIR rubber surround for higher SPL with a compact external diameter.
Mineral-infused paper cone for rigidity and damping.
Six-spoke, anti-resonant aluminum alloy basket with venting holes under the spider.
Diamond-cut basket edge featuring the Hertz logo for a premium look.
Terminal block supports 8 AWG cables for low-resistance wiring; plastic cover prevents accidental short circuits.
Can be mounted directly on the box wall for compact installation.
High-performance motor with superior magnetic field transfer.
