Frequently Asked Questions about PRO 16+


What is the nominal power of the Eton PRO 16+ speaker?

The Eton PRO 16+ is equipped with a nominal power of 70 watts RMS. This power allows the 6.5-inch speaker system to reproduce even demanding music pieces with clarity and precision. With a music handling capacity of 100 watts, the system can temporarily process higher levels, which is important for dynamic passages in music pieces. The high efficiency of 90 dB (1 W/m) ensures that even with moderate amplifier power, an impressively loud and clear sound is produced, making this system a top choice for sound enthusiasts. At the same time, distortion remains low to preserve the fidelity of the audio material.

What features does the textile tweeter in the PRO 16+ offer?

The PRO 16+ textile tweeter is hand-coated and has a diameter of 28 mm. It features a coupling volume that allows for improved rear sound diffusion. The compact design of the tweeter allows for flexible mounting, and thanks to the surface-mounted and flush-mounted housing options with swivel and tilt function, you can optimally align it. The combination of hand-coated material and these mounting options leads to finer high-frequency reproduction, making the highs appear clear and airy. This technology ensures a detailed and distortion-free reproduction of high frequencies, making the speaker an excellent choice for audiophile listeners.

What are the Thiele-Small parameters of the Eton PRO 16+ speaker?

The Eton PRO 16+ has a range of Thiele-Small parameters that characterize its performance. The resonance frequency (fr) is 72 Hz, and the mechanical Q factor (QMS) is 3.55. The electrical Q factor (QES) is 0.68, resulting in a total Q (QTS) of 0.57. The compliance of the suspension (CMS) is 0.41 mm/N, and the equivalent air volume (VAS) is 11 dm³. These parameters provide insights into the dynamic properties of the speaker. Additional values, such as the force factor BL of 4.8 Tm and the inductance of the voice coil of 0.34 mH, demonstrate the technical sophistication present in the PRO 16+.

How are the mounting options of the Eton PRO 16+ realized?

The mounting options of the Eton PRO 16+ are extremely versatile. The speaker features a powder-coated aluminum die-cast basket that not only provides stability but also ensures optimal ventilation. With an overall diameter of 165 mm and a cutout diameter of 142 mm, it fits into most standard openings. Thanks to the installation depth of 66.4 mm and the frame depth measurement of 4.8 mm, the speaker can be flush-mounted. The screw holes have a diameter of 4.5 mm, which facilitates common mounting options. The flexible housing options and the compact design of the Tweeter also allow for individual adaptation to various vehicle interiors.

What materials are used in the Eton PRO 16+?

The Eton PRO 16+ uses high-quality materials to ensure both sound quality and durability. The Tweeter is made from hand-coated fabric, carefully selected to produce clear highs. The diaphragm of the woofer is paper-coated and equipped with a strong ferrite magnet, enabling excellent bass reproduction. The basket of the speaker is made from aluminum die-cast, powder-coated for added durability, and provides excellent stability. The connection terminals are also of high quality to ensure a reliable connection, and the voice coil diameter is 25 mm, which ensures robust sound reproduction.

What installation dimensions should I consider for the Eton PRO 16+?

When installing the Eton PRO 16+, you need to consider some installation dimensions to ensure an optimal fit. The overall diameter of the speaker is 165 mm, and the cutout diameter is 142 mm. This allows it to fit well into many common car speaker openings. The installation depth of 66.4 mm is shallow enough not to interfere in tight installation situations. The frame has a depth of 4.8 mm, and the screw holes have a diameter of 4.5 mm. These dimensions allow for easy integration of the set into existing installations without the need for major modifications.

What impedance does the PRO 16+ have and what does that mean for performance?

The Eton PRO 16+ has a nominal impedance of 4 Ohm, making it well-suited for many common car audio Amplifiers. An impedance of 4 Ohm ensures that the speakers receive sufficient power from the amplifier, leading to optimal performance and sound quality. The DC resistance is 3.2 Ohm, indicating that the speaker can operate efficiently without consuming unnecessary energy. A lower impedance could theoretically lead to higher power, but it also increases the risk of overload and degradation of sound quality. Especially if you are looking for a powerful, clear sound, the PRO 16+ offers you an excellent balance.

How does the ferrite magnet affect the performance of the Eton PRO 16+?

The ferrite magnet in the Eton PRO 16+ plays a crucial role in converting electrical energy into acoustic energy. Ferrite is a popular material in speaker magnets because it is strongly magnetic and can be produced cost-effectively. Combined with the paper-coated diaphragm of this model, the magnet ensures powerful bass reproduction and accurate response, especially at low frequencies. This gives the speaker the ability to produce deep and precise bass that sounds impressive despite its compact design. The combination of diaphragm and magnet ensures that the speaker offers both performance and sound efficiency.

What role do the quality features of the Eton PRO 16+ play in sound production?

The quality features of the Eton PRO 16+, such as the powder-coated aluminum die-cast basket, the hand-coated paper diaphragm, and the high-quality terminal connections, significantly contribute to sound production. The aluminum basket provides stability and ventilation, minimizing distortion. The hand-coated diaphragm produces precise bass reproduction and works optimally with the strong ferrite magnet to promote clear, powerful sounds. The robust terminal connections ensure interference-free signal transmission, leading to an overall harmonious sound image. The selected combination of these materials not only ensures durability but also provides a sound performance that guarantees top-notch music playback.

How well is the frequency response of the PRO 16+ suited for demanding music?

The frequency response of the Eton PRO 16+ speaker is designed to accurately reproduce demanding music genres. With a resonance frequency of 72 Hz and an efficiency of 90 dB (1 W/m), the speaker system demonstrates excellent performance in both bass and treble. The combination of hand-coated fabric tweeter and paper-coated diaphragm contributes to a wide and expressive frequency response. Bass sounds deep and full, while treble is reproduced clearly and in detail. This makes the speaker ideal for anyone who wants to enjoy a wide range of music genres in the best quality, whether it's classical music or bass-heavy genres.
