More about the product
The Hertz MPBX300S2 is a premium 12-inch loaded subwoofer enclosure from the Mille Pro series, designed to deliver deep, powerful bass with exceptional precision. Built for enthusiasts who want high-quality low-frequency performance, this subwoofer box combines advanced acoustic design with durable materials to achieve outstanding sound reproduction in a compact form.
At the core of the MPBX300S2 is a Mille Pro 12-inch subwoofer featuring a rigid cone structure that ensures strength and minimises distortion. This design provides accurate bass response even at high power levels. The subwoofer is driven by a high-density ferrite magnet, offering excellent control and thermal stability for consistent performance during extended sessions.
The enclosure uses a sealed design, which produces tight, controlled bass with excellent transient response. This makes it ideal for music lovers who value clarity and accuracy over exaggerated boom. The box is built from robust MDF with internal bracing to reduce resonance and vibration, ensuring clean and distortion-free sound. Its compact footprint allows easy installation in a wide range of vehicles without sacrificing valuable space.
The MPBX300S2 enclosure is finished in a durable black carpet with the Hertz logo for a sleek, professional appearance. High-quality push terminals make wiring simple and secure, while the design ensures optimal airflow and cooling for the subwoofer.
This loaded subwoofer box is rated at 500W RMS and 1000W peak power, delivering strong output for demanding audio systems. It is optimised for use with external amplifiers that can provide clean, stable power to unlock its full potential.
While the MPBX300S2 excels in bass performance, it is designed to complement a full-range system rather than act as a standalone solution. Pairing it with quality midrange speakers and tweeters will create a balanced and immersive listening experience.
Overall, the Hertz MPBX300S2 offers a perfect blend of compact design, premium materials, and precision tuning, making it an excellent choice for those seeking high-quality bass in their car audio setup.
