Exceptional performance in a compact size, this is the goal of the Mille Pro car subwoofers. The cone of the MP 300 D4.3 is made with pressed paper pulp and mineral powders injection. The V-cone® profile increases stiffness, allowing the cone to operate like a piston. The enclosure materials are made from high-purity IIR-butadiene rubber.

The Mille PRO subwoofers are built with Boundary Free Surround technology, allowing for a larger radiating surface with the same diameter, creating higher sound pressure. The compact basket with anti-resonance 6-spoke aluminum alloy contributes to the mechanical damping of the subwoofer.

The 4 Ω + 4 Ω DVC composite resistance configuration improves flexibility to match any amplifier system. The air cooling and decompressing system eliminates the need for a central hole in the bottom plate.

• Better thermal inertia for low operating temperatures.
• Maximization of the magnetic field.
• Ability to mount the subwoofer right against the wall of the box.

The rubber damping disc secures the subwoofer in the box and ensures air exchange for the 10 openings at the bottom. Holes behind the voice coil winding ensure greater air exchange with the internal layers of the coil.

The terminal uses compact pressure connections with an antishort circuit cover to provide extremely low wiring resistance in low composite resistance configurations.
