Frequently Asked Questions about Uno X 690

What is the power handling capacity of the Hertz UNO X 690 speaker?

The Hertz UNO X 690 has a continuous power handling capacity of 85 watts and a peak power of 340 watts. These performance parameters indicate that the speaker is suitable for both normal and particularly powerful audio playback. The high power handling allows for a clear sound image without distortion even at higher volumes. This design ensures consistently high sound quality, especially with music pieces that have dynamic frequency changes. The impedance of 4 ohms is typical for many car speakers and works well with most common car radios or amplifiers, making integration into existing sound systems easier.

What materials are used in the Hertz UNO X 690?

The Hertz UNO X 690 uses a combination of high-quality materials. The tweeter diaphragm is made of polyetherimide (PEI), known for its stability and low-resonance sound properties. The woofer is equipped with a water-resistant pressed paper diaphragm that is both lightweight and stiff, allowing for precise bass reproduction. The woofer magnet is made of high-density ferrite, ensuring efficient magnetic flux conduction. The tweeter magnet is also made of ferrite to ensure clear and undistorted highs. This choice of materials achieves a balanced sound image from deep bass to clear highs.

What is the frequency response of the Hertz UNO X 690?

The Hertz UNO X 690 covers a frequency response from 45 Hz to 22 kHz. This range indicates that the speaker reproduces both deep bass and high-frequency tones across a considerable bandwidth. Notably, the dual 15 mm piezo super tweeter extends the frequency response up to 20 kHz, maximizing the stereo image and allowing for particularly detailed representation of the highs. This setup allows the listener to experience a full sound field with deep, mid, and high frequencies, making the speaker ideal for various music genres.

What are the dimensions of the Hertz UNO X 690 speaker?

The Hertz UNO X 690 has physical dimensions that increase its installation versatility. The total height is 91 mm, the cutout size is 162.2 mm. The total length of the speaker is 237.3 mm, while it is 224 mm wide. Additional measurements such as 264 mm in width and 154 mm in height ensure a precise installation option in suitable speaker cutouts. These dimensional details are crucial to ensure that the speaker can be seamlessly integrated into existing vehicle partitions or special speaker mounts without the need for mechanical adjustments.

What features does the magnet material of the UNO X 690 speakers have?

The woofer of the Hertz UNO X 690 uses a ferrite magnet with high flux density to ensure maximum efficiency in converting electrical energy into sound. The tweeter magnet is also made of ferrite to ensure consistent performance at high frequencies. Such materials are known for their reliability and durability, effectively reducing distortion and significantly contributing to clear and accurate sound reproduction. The difference lies in the ability of these materials to provide consistent sound performance, even at high power output, thus ensuring the best possible acoustic efficiency.

How does the voice coil affect the sound quality of the Hertz UNO X 690?

The voice coil of the Hertz UNO X 690 is available in two specific versions: a 25 mm size for the woofer and a 20 mm size for the tweeter. Such dimensions guarantee precise and responsive sound reproduction. These voice coils optimize the control of the diaphragm movement, leading to accurate sound imaging and quick response. Especially during frequency changes, it is important that the coils can quickly respond to changes to minimize distortion and keep the sound image sharp and clear. This is qualitatively beneficial for the differentiated reproduction of complex musical characteristics.

What tips are there for installing the Hertz UNO X 690 speaker in the vehicle?

When installing the Hertz UNO X 690, it is important to pay attention to the exact measurements: The installation depth is 91 mm and the required cutout has a diameter of 162.2 mm. These precise dimensions require careful planning before installation to ensure that the speaker fits perfectly into the vehicle cutouts. Correct placement without the need for structural modifications to the vehicle is key to optimal sound and stable resonance. Additionally, cable connections should be made neatly to minimize signal loss and maximize sound quality.

Are there any special features in the frequency response of the high-frequency range in the UNO X 690?

Yes, the high-frequency range of the Hertz UNO X 690 is characterized by its dual 15 mm piezo super tweeter with a PEI dome, which extends the frequency response up to 22 kHz. This extension ensures that the speaker reproduces even the finest details of the upper frequencies, contributing to a balanced and complete sound image. This not only results in brilliant highs but also intensifies the overall stereo experience. The piezo super tweeter allows for smooth and distortion-free high-frequency reproduction, especially in music pieces with a wide dynamic range.

How is the stereo sound maximized in the Hertz UNO X 690?

The Hertz UNO X 690 maximizes stereo sound through a precise interplay of its components, particularly the dual 15 mm piezo super tweeter with a PEI dome. This significantly extends the frequency response, leading to improved stereo imaging. The efficiency of these tweeters, combined with the large 25 mm woofer voice coil and the water-resistant pressed paper diaphragm, results in a seamless transition between bass and high frequencies, giving the listening experience remarkable spatial depth. The clear separation of frequencies also ensures a highly precise and authentic sound perception.

How does the material of the diaphragm affect the sound of the UNO X 690?

The diaphragm of the Hertz UNO X 690 is made of water-resistant pressed paper, which enhances both sound efficiency and durability. This material choice allows for precise and dynamic bass reproduction, while the protective layer reduces resonance and distortion. Since pressed paper is lightweight and stiff, it achieves excellent sound quality by minimizing unwanted resonance effects. It also withstands harsh environmental influences, which is particularly advantageous in automotive applications. Through this combination of acoustic and physical resilience, the speaker offers a reliable acoustic experience over a long period.
