Frequently Asked Questions about CXS 28+

What are the main features of the Eton CXS 28+ Tweeter?

The Eton CXS 28+ is a high-quality Dome Tweeter equipped with a robust 28 mm voice coil diameter. It uses a powerful neodymium magnet that helps to clearly reproduce the finest details in music. The coated fabric dome ensures rich high-frequency performance. With an impedance of 8 Ohm and a recommended frequency range of 2.4 - 22 kHz, the tweeter offers optimized radiation characteristics. In addition to a mid-range sound pressure level of 90 dB at 1 W/1 m, the CXS 28+ is particularly compact, facilitating easy installation. It comes with a special mounting and surface-mount housing that allows for tilt and swivel functionality.

What technical specifications characterize the Eton CXS 28+?

The Eton CXS 28+ has a nominal impedance of 8 Ohm and a total moving mass, including air mass, of 0.26 g. It has a DC resistance of 6.5 Ohm and an effective diaphragm area of 8.1 cm². The inductance of the voice coil is 0.03 mH, and the resonance frequency of the tweeter is set at 1340 Hz. These technical specifications contribute to the exceptional sound performance of the CXS 28+ by ensuring it harmonizes with vehicles equipped with demanding audio components. The use of neodymium as the magnet material further increases efficiency and reduces size.

How is the CXS 28+ Tweeter installed in the car?

The installation of the CXS 28+ in the vehicle is facilitated by its compact design. The included mounting and surface-mount housings provide tilt and swivel functionality, allowing flexibility in positioning. The dimensions allow for easy integration into common vehicle models. It is important that the effective diaphragm area of 8.1 cm² of the tweeter does not restrict installation options. The installation should be done in an area where sound waves can be freely directed into the passenger compartment to ensure optimal high-frequency reproduction.

What sound advantages does the fabric dome of the CXS 28+ offer?

The CXS 28+ uses a newly developed coated fabric dome that, in combination with the 28 mm voice coil, achieves impressive high-frequency performance. This dome ensures that voices sound smooth and full while simultaneously revealing the finest dynamic details of the music. The structure of the fabric surface helps minimize distortion and enables precise sound reproduction. In conjunction with the neodymium magnet, the CXS 28+ ensures that the sound remains clear and defined even at high volumes, which is particularly important for discerning listeners.

How does the neodymium magnet affect the performance of the CXS 28+?

The use of an extremely powerful neodymium magnet in the CXS 28+ Tweeter has decisive advantages for sound quality. Neodymium is known for its high magnetic flux density, which means it provides strong magnetic force at low mass. This leads to a more efficient drive of the voice coil, making more details in the upper frequency range discernible. At the same time, the dynamic properties are improved, allowing for precise and clear sound reproduction even at high volumes. The compact magnet thus enhances the performance of the tweeter without additional weight or volume.

For which frequency ranges is the Eton CXS 28+ optimized?

The Eton CXS 28+ Tweeter is optimized for the reproduction of high-frequency sounds in a recommended frequency range of 2.4 to 22 kHz. This range ensures excellent high-frequency reproduction and is ideal for conveying musical details and fine sound nuances that may be lost with conventional speakers. The resonance frequency of the tweeter is 1340 Hz, which means it can also start at lower frequencies in this range to ensure a seamless transition to the midrange drivers. This optimization makes the CXS 28+ excellent for HiFi systems in vehicles.

What role does the voice coil play in the Eton CXS 28+ Tweeter?

The 28 mm voice coil of the Eton CXS 28+ is an essential element for the sound quality and performance of the tweeter. With an inductance of 0.03 mH and a nominal impedance of 8 Ohm, it ensures efficient conversion of electrical into mechanical drive that moves the fabric dome. The DC resistance of the voice coil is 6.5 Ohm, achieving an optimal balance between power consumption and heat dissipation. These technical specifications enable the voice coil to deliver linear and detailed reproduction of high frequencies even at high volumes.

How does the optimized omnidirectional characteristic contribute to the sound quality of the CXS 28+?

The optimized omnidirectional characteristic of the CXS 28+ results from the newly developed dome geometry and the small coupling volume with integrated damping pads. These features ensure that the Tweeter radiates sound evenly in all directions. This guarantees that high frequencies are perceived uniformly throughout the vehicle, regardless of the listeners' seating position. This is particularly important for the soundstage and spatial representation of music. HiFi enthusiasts who value accurate and wide-ranging sound images will especially appreciate this feature.

What do the specific Thiele-Small parameters mean for the Eton CXS 28+?

The Thiele-Small parameters of the Eton CXS 28+ describe the electroacoustic properties of the Tweeter. The resonance frequency of 1340 Hz indicates at which frequency the Tweeter is most resonant. The effective diaphragm area of 8.1 cm² and the voice coil inductance of 0.03 mH influence how the Tweeter responds to different frequencies. These parameters help audio engineers model the behavior of the Tweeter in conjunction with other speakers to design a system with optimal sound quality. They are essential for tuning the Tweeter to the acoustic requirements of the vehicle.

How does the average sensitivity affect the performance of the CXS 28+?

The average sensitivity of the CXS 28+ is 90 dB at 1 Watt/1 Meter, a value that significantly contributes to the loudness of the Tweeter. A higher sound pressure level means that the Tweeter requires less power to achieve a certain volume, making it efficient. This is particularly advantageous in vehicles, as it allows for clear and powerful sound even at low amplifier power. The high sound pressure level ensures that the high-frequency representation remains intact even in loud environments, providing a pleasant and uninterrupted sound experience in the car.
