Hertz MP28.3 1.38″ 180W Tweeters

The MP28.3 inherits all the technological features of the Mille Legend ML28.3 in a smaller diameter tweeter component. The Tetolon dome’s design optimises off-axis listening dispersion. The dampening material in the rear acoustic chamber helps to extend response to lower frequencies, with a resonance frequency of only 900 Hz. The crossover point between the tweeter and the woofer can be decreased in this fashion, which improves the sound image in the automobile dashboard. The large Neodymium motor reduces nonlinearity while controlling a music programme with fast transients. The CCAW voice coil (Copper Clad Aluminium Wire) ensures a light weight and robust moving assembly. These technological features interact to provide a high frequency extension of 28kHz, which is a world record for a tweeter with a 28mm voice coil. The MP28.3 tweeter comes with an elegant and compact angled tweeter support that enables for easy installation on both the A-pillars and the automobile dashboard. The correct tweeter angle increases the stereo image, which is crucial for excellent listening.

Legendary Origins

Hertz has a strong following due to their reputation for excellent sound. The Mille MP28.3 PRO 1-3/8″ tweeters, which inherit technological advantages from Hertz’s Mille Legend Series continue their hot record. The Tetolon fibre dome, which is powered by a neodymium magnet, expands the frequency range of your system while prioritising control for a precise, lifelike sound. Power handling, frequency response, and volume are all improved by a specially built rear acoustic chamber. To ensure the optimal fit in your vehicle, Hertz delivers hardware for a variety of installation options.

The Hertz State Of Mind

A good speaker such as the MP28.3 according to Hertz should reveal the emotional strength of the music you enjoy. That’s a difficult standard to meet but they’re up to the task thanks to their commitment to high-quality components and cutting-edge design. Hertz is made up of music fans that are dedicated to making your car’s sound system the best it can be for optimum audio enjoyment.

MP28.3 Features:

• FEA simulations were used to design the Tetolon Fiber dome for superior dynamics and angle dispersion
• FEA models were used to improve a double Neodymium magnet for optimal field symmetry and transfer efficiency
• For greater damping and more natural acoustic emission, the rear chamber has been extended and filled with natural fibre non-woven sound-absorption material
• For superior power handling, a massive 28 mm CCAW (Copper Clad Aluminium Wire) ferrofluid-cooled movable voice coil is used
• 900Hz FS ensures a well-dampened high-pass frequency roll-off, allowing for a low cut-off frequency crossover point
• Faceplate with FEM (Finite Element Modeling) optimised geometry for off-axis installations with good linearity
• For easy OEM integration, a wide range of installation accessories is available
• Separate ultra-compact crossover with level adjustment switch for convenience and flexibility of installation (0, -2dB)
