1 / 4
The Hertz MP 28.3 PRO delivers very detailed, smooth high-frequency detail and strong power handling; angled pods and compact crossovers make mounting simpler. Most reviewers found them loud and dynamic, though some users performed EQ or used a DSP to flatten the response.

Review highlights
Based on customer reviewsHertz MP 28.3 PRO — detailed, powerful tweeters with flexible mounting
The Hertz MP 28.3 PRO delivers very detailed, smooth high-frequency detail and strong power handling; angled pods and compact crossovers make mounting simpler. Most reviewers found them loud and dynamic, though some users performed EQ or used a DSP to flatten the response.
What buyers praise
- Very detailed, revealing high-frequency clarity
- Strong SPL and power handling for dynamic output
What to watch for
- Perceived loudness can vary by system; a few users reported insufficient output
Overview
MP 28.3 Mille Pro 28 mm diameter tweeter component inheriting all the technological features of the Mille Legend ML28.3. The geometry of the Tetolon dome maximizes the typical dispersion of off-axis listening. The rear acoustic chamber with damping material contributes to extend response to lower frequencies achieving a resonance frequency of only 900 Hz. In this way the crossover point between tweeter and woofer can be lowered, improving the sound image in the car dashboard. The massive Neodymium motor minimizes nonlinearity managing the music program with very dynamic transients. The CCAW (Copper Clad Aluminium Wire) voice coil guarantees an especially light weight and stiff moving assembly. These technological elements interact with each other, resulting in a high frequency extension of 28kHz, a record for a tweeter featuring a 28mm voice coil. An elegant and compact angled tweeter support is provided with the tweeter: this allows easy installation both on the A-pillars and on the car dashboard. The correct angle of the tweeter improves the stereo image, essential for an engaging listening.
