The aluminum die-cast basket is equipped with a ferrite magnet and a polished base plate. A nominal impedance of 4 Ohm, 70 W RMS power, and an efficiency of 90 dB ensure excellent sound quality. The crossover with level adjustment allows for precise sound tuning. The force factor BLxI is 4.8 Tm, Xmax mechanically is +/- 9.0 mm, and the resonance frequency is 72 Hz. These technical specifications make the set ideal for demanding sound installations.

How do I install the 2-way component system from ETON in the car?

For the installation of the ETON PRO 175 in the car, note: The installation depth is crucial for the optimal fit of the 6.5-inch (16.5 cm) Speaker Set. The effective cone area is 137 cm², which must be considered in doors and panels. With 4 Ohm impedance and 70 W RMS power, correct wiring is also essential. The crossover with level adjustment facilitates sound tuning, while the adaptation to the onboard network takes into account the DC resistance of 3.2 Ω and the inductance of the voice coil of 0.34 mH. This technical integration maximizes sound performance.

What materials are used in the ETON PRO 175 Speaker Set?

The ETON PRO 175 Speaker Set uses high-quality materials that are crucial for sound quality. The cones are made from a hand-coated, air-dried paper cone that allows for clear sound reproduction. The tweeters are made from 25 mm hand-coated fabric. The speaker basket is made from powder-coated aluminum die-cast, providing high stability and durability. Additionally, the set uses ferrite as the magnet material, known for its efficiency. This combination of materials ensures a robust, durable, and high-quality speaker.

What is the load capacity of the ETON PRO 175 speaker system?

The ETON PRO 175 Speaker Set impresses with excellent load capacity values. The nominal power is 70 watts RMS, with a music load capacity of up to 100 watts. These power values allow for high volumes without distortion, which is particularly attractive for music lovers. The speaker operates efficiently with an efficiency rating of 90 dB at a sound pressure level of 1 W / 1 m. These values are particularly consistent for automotive use, as they guarantee consistently high sound quality even at higher volumes and across various music genres.

What frequencies can the ETON PRO 175 system reproduce?

The ETON PRO 175 system offers precise sound reproduction through its well-thought-out technical structure. The resonance frequency of the system is 72 Hz, which means that deep bass tones are efficiently transmitted. In combination with the hand-coated paper diaphragm and the 25 mm textile dome tweeters, the system covers a wide frequency range. The crossover with level adjustment allows for additional fine-tuning of the sound frequencies to optimize according to individual needs. These features make the ETON PRO 175 ideal for detailed music events.

What Thiele-Small parameters are available for the ETON PRO 175?

The ETON PRO 175 lists several relevant Thiele-Small parameters that describe the sound characteristics. The resonance frequency fr is 72 Hz, while the force factor BLxI is 4.8 Tm, ensuring high efficiency in the drive. The mechanical Q value QMS is 3.55, the electrical Q value QES is 0.68, and the total Q value QTS is 0.57. These parameters are important for understanding the acoustic behavior of the speaker system in various enclosures. The compliance of the suspension CMS is 0.41 mm/N, contributing to rich sound reproduction.

What impedance does the ETON PRO 175 Speaker Set have and why is it important?

The ETON PRO 175 Speaker Set has a nominal impedance of 4 Ohm. This value is crucial for matching with most amplifier units in the automotive sector. A correctly tuned impedance ensures that power transfer occurs efficiently without excessive heat generation or power losses. At 4 Ohm, the speaker is capable of accepting high currents, leading to better dynamics and sound precision. A DC resistance of 3.2 Ohm supports this specification and enhances its suitability for common car audio amplifiers.

What mechanical mobility does the ETON PRO 175 Speaker Set offer?

The ETON PRO 175 Speaker Set is equipped with an Xmax mechanical displacement of +/- 9.0 mm. This allows for considerable mobility of the diaphragm when reproducing low frequencies without distortion. The compliance of the suspension CMS is 0.41 mm/N, supported by a mechanical resistance RMS of 1.62 kg/s. These technical features promote accurate reproduction of bass signals, while the effective diaphragm area of 137 cm² ensures efficiency in converting electrical energy into sound. The high mechanical mobility is ideal for dynamic sound.

What advantages does the ferrite magnet in the ETON PRO 175 speaker offer?

The ferrite magnet in the ETON PRO 175 is a crucial feature that contributes to the stability and performance of the speaker. Ferrite is known as a magnet material for its resistance to demagnetization and temperature changes, which is particularly beneficial in the automotive sector, where temperature and humidity conditions can fluctuate. The strong magnet aids in the efficient conversion of electrical signals into acoustic energy, supported by the large core bore of the base plate. This results in a better sound image, higher sensitivity, and an improved sound pressure level, enabling an intense listening experience.

What sound quality can I expect from the ETON PRO 175 Speaker Set?

The ETON PRO 175 Speaker Set delivers excellent sound quality through its thoughtful design and material selection. The achieved efficiency of 90 dB at 1 W / 1 m leads to high sensitivity and effective volume levels. The combination of the hand-coated paper-based diaphragm and the 25 mm textile dome tweeters guarantees a clearly defined sound reproduction over a wide frequency range. The built-in crossover allows for level adjustments to customize the sound. The use of ferrite magnets and a robust aluminum die-cast basket additionally ensures a stable and rich sound, ideal for demanding audio applications.
