More about the product
The Hertz MP70.3 is a high-performance 3-inch midrange speaker designed for audiophiles who demand clarity and precision in their car audio system. Part of the Mille Pro series, this speaker delivers exceptional sound reproduction with a focus on natural vocals and detailed midrange frequencies. Its compact size makes it ideal for multi-way systems where space is limited but sound quality cannot be compromised.
The MP70.3 features a pressed-pulp cone combined with cotton fibres, a design that enhances rigidity while maintaining lightness for accurate sound response. This material choice ensures smooth and natural tonal characteristics, reducing distortion even at high volumes. The speaker also incorporates a low-loss rubber surround, which improves linearity and extends the frequency range for a more dynamic listening experience.
A key highlight of the MP70.3 is its neodymium magnet system, which provides strong magnetic energy in a compact form. This allows for better control of the voice coil, resulting in precise sound reproduction and improved efficiency. The 20mm copper-clad aluminium voice coil further enhances thermal stability and power handling, making the speaker suitable for demanding audio setups.
Installation flexibility is another strength of the MP70.3. Its shallow mounting depth and compact dimensions make it easy to integrate into custom builds or factory locations without sacrificing performance. The speaker is optimised for use in sealed enclosures, ensuring consistent and controlled sound output.
While the MP70.3 excels in midrange clarity, it is designed to work as part of a multi-way system rather than a standalone speaker. It does not produce deep bass or extended treble, so pairing it with dedicated woofers and tweeters is recommended for a full-spectrum sound experience.
Overall, the Hertz MP70.3 combines advanced materials, precise engineering, and compact design to deliver outstanding midrange performance for serious car audio enthusiasts.
