Hertz Mille MP 300 D4.3 12in 4 Ohm 600 Watts RMS Subwoofer

The Sub At A Glance:

• Power handling: Handles 600 Watts RMS and 1200 Watts Max for forceful low-frequency output.
• Dual voice coils: The 4 Ohm + 4 Ohm DVC configuration provides versatile amplifier-matching options.
• Rigid V-cone: Pressed paper pulp injected with mineral powders increases rigidity and helps the cone operate like a piston.
• Boundary Free Surround: High-purity IIR-butyl rubber and Boundary Free Surround technology provide a greater emission surface for higher sound pressure.
• Anti-resonant frame: A compact 6-spoke aluminum-alloy basket supports mechanical damping while remaining transparent to the sound.
• High-excursion voice coil: The 65 mm, 4-layer voice coil uses a TIL-P former to deliver high linear displacement.
• Advanced cooling: Voice-coil openings and 10 bottom-plate vents move air through the air gap to help maintain low operating temperatures.
• Installation flexibility: A 164 mm mounting depth and center-hole-free bottom plate allow installation directly against the enclosure wall; the included damping rubber disk maintains airflow to the vents.

The MP 300 D4.3 brings depth and physical impact to music without demanding excessive mounting space. Its rigid cone profile and expanded emission surface turn low notes into a deep, pressurized rumble you can feel throughout the vehicle, while the high-displacement voice coil gives bass hits weight and authority.

Built around technology and materials derived from Hertz’s Mille Legend line, this subwoofer balances hard-hitting output with durable construction and practical installation. Solid push terminals with an anti-short-circuit cover accept cables up to 8 AWG for low-resistance connections.
