Frequently Asked Questions about Uno K 170


What is the continuous power handling of the Uno K 170 Speaker Set?

The Uno K 170 Speaker Set from Hertz has a continuous power handling of 70 Watts. This power rating indicates the speaker's ability to handle a certain power level continuously without suffering damage or sound quality loss. This specification is particularly important if you aim for long listening sessions or operation at higher volumes. The peak power handling is 280 Watts, which is designed for short-term power peaks.

What frequency ranges does the Uno K 170 Speaker Set cover?

The Uno K 170 Speaker Set offers a frequency response of 55 Hz to 23 kHz. This range allows the speaker set to reproduce both deep bass and high-frequency components clearly. Such a frequency response is especially useful if you want to experience a wide range of sound details in your music or audio. The integrated 6 dB/octave crossover system supports a clean frequency transition between the components.

What is the impedance of the Uno K 170 Speaker Set?

The Uno K 170 Speaker Set has an impedance of 4 Ohms. This technical specification is crucial for matching with the Amplifier, as a lower impedance requires more power to produce a comparable sound pressure level. Especially if you want to use the speaker with different types of Amplifiers, it is important that the impedance is compatible to ensure the best possible sound and reliability of your audio system.

What are the sizes of the components of the Uno K 170 Speaker Set?

The main components of the Uno K 170 Speaker Set have the following dimensions: The woofer has a diameter of 6.5 inches, while the woofer voice coil has a diameter of 25 mm. The tweeter, responsible for the high frequencies, has a diaphragm diameter of 24 mm and a voice coil diameter of 14 mm. When installing, you should note that the woofer has an outer diameter of 165 mm, with a mounting depth of 51 mm.

Where should the Uno K 170 speakers be installed in the car?

When installing the Uno K 170 speakers in the car, you need to consider the dimensions of the speakers. The woofer has a mounting diameter of 165 mm and a depth of 51 mm, which means it is suitable for most common installation locations in vehicles, but the specific compatibility with your vehicle should still be checked. It is important to ensure the correct mounting depth to avoid unwanted vibrations or unfavorable mounting.

What are the physical properties of the Uno K 170 Tweeter?

The Tweeter of the Uno K 170 has a diaphragm diameter of 24 mm and is designed to reproduce high frequencies accurately and clearly. It integrates into the crossover system with a slope of 6 dB/octave, ensuring a smooth transition between the Woofer and Tweeter. The weight of the Tweeter is 0.53 kg, which provides a stable installation system without creating unnecessary strain, which could be important for balance in the vehicle.

How sensitive is the Uno K 170 Speaker Set?

The sensitivity of the Uno K 170 Speaker Set is specified at 93.5 dB SPL (Sound Pressure Level). This metric indicates how efficiently the speaker converts the input power level into sound. Higher sensitivity means that the Speaker Set sounds louder at lower amplifier power, which is particularly advantageous when used in lower-powered systems. Sensitivity directly affects the volume and sound quality in your installation.

What is the weight of the individual components of the Uno K 170?

The weight of a component of the Uno K 170 Tweeter is 0.53 kg, while the crossover filter weighs 0.03 kg. The relatively low weight of the crossover filter allows for flexible installation without additional structural requirements. Together, both components ensure a combination of performance and flexibility in installation without compromising sound quality or robustness.

What are the diameters of the voice coils in the Uno K 170 Set?

In the Uno K 170 Speaker Set, the Woofer has a voice coil diameter of 25 mm, while the Tweeter has a voice coil diameter of 14 mm. These voice coils are crucial for the movement of the diaphragms that produce sound. Especially when you use speakers for power and precision, these voice coil diameters provide a balanced mix of powerful bass reproduction from the Woofer and fine treble performance from the Tweeter.

What types of crossovers are integrated into the Uno K 170 Speaker Set?

The Uno K 170 Speaker Set integrates a crossover type of 6 dB/octave for the Tweeter. This feature describes how the frequency distribution between the Woofer and Tweeter is managed. A gentle transition curve with this slope ensures that the frequency components are allocated correctly, providing both sonic clarity and a consistent sound across the entire frequency range. Particularly relevant when you desire clean and natural sound reproduction.
