More about the product
The Hertz MP300D4.3 Mille Pro 12-Inch Subwoofer is designed for car audio enthusiasts who want deep, powerful bass with precision and control. As part of the Mille Pro series, this subwoofer combines advanced engineering and premium materials to deliver exceptional low-frequency performance without compromising clarity.
The MP300D4.3 features a water-repellent pressed paper cone, which provides excellent rigidity and lightness for fast, accurate movement. This design ensures impactful bass notes with detail and control. The cone is paired with a low-loss rubber surround that allows smooth excursion while minimising distortion, even at high output levels.
The motor structure uses a high-quality ferrite magnet that generates strong magnetic flux for precise cone control. This results in tight, responsive bass that maintains clarity at all volumes. The frame is built from a durable alloy to reduce unwanted vibrations and resonance, ensuring cleaner sound. Venting in the motor system improves airflow and cooling, helping maintain consistent performance during extended listening sessions.
The MP300D4.3 is designed for installation in sealed or ported enclosures, giving flexibility to achieve the preferred bass response. Its 12-inch size makes it ideal for those who want more depth and output compared to smaller subwoofers, while still fitting into a wide range of vehicles.
While the MP300D4.3 excels in low-frequency reproduction, it is intended to work as part of a complete audio system with dedicated midrange drivers and tweeters for full-range sound. It does not include built-in amplification or DSP features, focusing instead on pure subwoofer performance.
Overall, the Hertz MP300D4.3 Mille Pro Subwoofer offers a balance of power, precision, and durability, making it an excellent choice for upgrading a car audio system with strong, detailed bass.

The Hertz MP300D4.3 Mille Pro Subwoofer suits car audio enthusiasts seeking strong, detailed bass with more depth than smaller models. It is ideal for mid to high-end systems where clarity and flexibility are important. Compared to entry-level subwoofers, it offers superior materials and engineering for better sound quality. However, it does not include built-in amplification, so it works best when paired with a suitable external amplifier and matching Mille Pro components for full-range performance.
