Frequently Asked Questions about ECX-G4

What membrane technology is used in the ECX-G4 and what sound advantages does it offer?

The 4-inch coaxial speaker ECX-G4 from Emphaser features a CRYSTALGRAIN compound membrane, specifically designed for optimal sound performance. This membrane technology allows for improved reproduction of high and mid frequencies, resulting in an incredibly clear and precise sound. Especially if you enjoy listening to music at high volumes, you'll notice that distortions are minimal and sound details remain audible. Additionally, the compound membrane is lightweight, which increases speed, and robust, ensuring a long lifespan. This advanced membrane technology is a key feature that makes the ECX-G4 an outstanding speaker.

How does the temperature management of the ECX-G4 work through the FlowMax aluminum die-cast basket?

The temperature management of the ECX-G4 is optimized by the FlowMax aluminum die-cast basket. Thanks to its special design, the aluminum basket efficiently dissipates the heat generated, contributing to the speaker's performance and longevity. Especially at high volumes or during intense use, the temperature can rise quickly, but due to the high thermal conductivity of aluminum, the operating temperature remains stable. At the same time, the die-cast basket provides stability and minimizes vibrations that could affect sound quality. This combination of structure and material choice allows for a precise and clear sound image even under demanding conditions.

What effect does the strontium ferrite magnet have on the ECX-G4 speaker?

The strontium ferrite magnet in the Emphaser ECX-G4 is a technical highlight that significantly enhances the efficiency of the speaker. Strontium ferrite provides a stronger magnetic flux than conventional ferrite magnets, improving the driving strength of the voice coil. This not only increases sensitivity but also the dynamics of the sound transducer frequency response control. You get a livelier, more detailed sound when listening to music, even at low volumes. The choice of this high-quality magnet material is crucial for the overall performance of the speaker and underscores the high-quality construction of the ECX-G4, which ensures a long lifespan and consistent sound performance.

What influence does the butyl rubber surround have on the sound characteristics of the ECX-G4?

The butyl rubber surround in the ECX-G4 plays a crucial role in the sound dynamics and longevity of the speaker. This flexible component ensures that the diaphragm can move optimally, leading to improved sound reproduction and minimal distortion. Additionally, butyl is known for its weather resistance and durability, allowing the speaker to reliably perform even in extreme climatic conditions. The damping of unwanted resonances is another effect of this surround, resulting in a clear and balanced sound image, whether in the car or in another installation location.

What technical specifications does the ECX-G4 have regarding the voice coil and the Tweeter?

The ECX-G4 speaker is equipped with a dual-layer copper wire voice coil, wound onto a temperature-resistant aluminum voice coil former. This combination allows for high load capacity while providing protection against overheating. This is important when you listen to music intensively, as the temperature can rise quickly. The 13 mm Tweeter with a textile dome ensures excellent reproduction of high frequencies and integrates seamlessly into the overall system of the speaker. Together, these elements create a powerful sound unit that elevates the speaker's performance to a high level.

What frequencies does the Emphaser ECX-G4 cover and what sound advantages does this offer?

The Emphaser ECX-G4 has a frequency response of 95 Hz to 22 kHz, covering a wide range and accurately reproducing both low and high tones. Particularly noteworthy is its ability to present high frequencies clearly and without distortion, while the low frequencies sound voluminous and powerful. This range is ideal for music lovers who enjoy both bass-heavy and treble-rich music genres. The speaker's ability to adapt to a variety of musical styles is facilitated by its precise capture of sound dynamics, without a reduction in sound quality at high volumes.

How do the sensitivity and nominal power handling of the ECX-G4 affect performance in everyday use?

With a sensitivity of 84 dB (1W/1m) and a nominal power handling of 60 watts RMS, the ECX-G4 offers robust performance. These technical parameters ensure that the speaker can achieve relatively high volumes even at low input levels. For you, this means a more enjoyable listening experience, even when the audio system is not turned up to full volume. The 60 watts RMS guarantee that the speaker remains stable at louder levels and does not produce distortion. This combination of sensitivity and power handling is optimally designed for demanding musical pieces to ensure a clear and captivating audio experience.

What are the dimensions of the Emphaser ECX-G4 and what does that mean for installation in different vehicles?

The Emphaser ECX-G4 has a mounting diameter of 93 mm and a mounting depth of 45 mm. These compact dimensions make the speaker particularly versatile, as it fits into many standardized mounting openings. If you are planning to install it in a vehicle, these dimensions are crucial to ensure that the speaker is optimally integrated into the environment, both spatially and acoustically. Thanks to the low mounting depth, the speaker is especially suitable for vehicles that offer less space in the door panels - important for a clean acoustic installation.

What is the role of the Connex centering spider in the ECX-G4 speaker design?

The Connex centering spider with woven voice coil lead in the ECX-G4 significantly contributes to the strength and positioning of the diaphragm. This component keeps the voice coil centered and ensures that it moves evenly, which is essential for sound fidelity. Especially at high volumes, the precise guidance is ensured by the stability of the Connex centering spider. The woven lead minimizes potential contact issues and contributes to the reliability of the speaker. This ensures that with prolonged use, a consistently high sound quality is maintained without deformation or other sound losses.

What advantages does the Emphaser screw terminal with gold-plated contact surfaces offer in the ECX-G4?

The Emphaser screw terminal with gold-plated contact surfaces in the ECX-G4 primarily offers improved electrical conductivity. The gold plating minimizes contact issues that could arise from corrosion or oxidation. This helps ensure a long-term, stable connection, which is particularly important when the speaker is operated in environments with changing climatic conditions. The easy installation through the screw terminals, which ensure a firm hold of the cables and provide the possibility to securely attach different cable cross-sections, is practical. This technical sophistication contributes to the overall durability and thus to the reliability and consistent performance of the speaker.
