ESX QXE8.2C Datasheet

Frequently Asked Questions about QXE8.2C


What advantages does the 20 cm diameter of the QXE8.2C Speaker Set offer?

The QXE8.2C from ESX provides significantly improved sound quality with its 20 cm diameter compared to the more common 6.5 inch speakers. The larger diameter allows for deeper bass reproduction and enhances overall acoustic performance. The diaphragm can move more air due to the larger surface area, resulting in a fuller and more powerful bass. Combined with the neodymium drive and fiberglass diaphragms, this ensures a perfect balance between performance and quality. Additionally, the speaker is compatible with standard 20 cm adapters, making installation in various vehicle models easier and offering extra flexibility for customizing individual sound preferences.

How does the neodymium drive of the QXE8.2C differ from conventional speakers?

The neodymium drive in the QXE8.2C from ESX uses N45 neodymium magnets, which provide high efficiency and exceptional power for precise sound reproduction. Compared to conventional magnets, neodymium is lighter and more compact, resulting in a reduced installation depth. This allows for more flexible installation and an overall lighter speaker construction. Furthermore, the use of neodymium leads to improved heat resistance and stability, minimizing distortion and ensuring clear sound quality even at high volumes. Especially if you enjoy listening to music loudly, you will notice the difference.

What distinguishes the inline Crossover of the QXE8.2C?

The inline Crossover optimized for the QXE8.2C is crucial for efficient signal processing and sound distribution within the Speaker Set. It separates the frequencies and directs them to the respective drivers: The woofer handles the range between 35 Hz and 5000 Hz, while the Tweeter takes over frequencies from 3500 Hz to 24000 Hz. This precise frequency separation results in clear and detailed sound reproduction. The detachable threaded mounts integrated into the Crossover also allow for flexible installation options, enabling the Speaker Set to be adapted to various vehicle conditions.

What technical advantages does the fabric neodymium Tweeter of the QXE8.2C offer?

The fabric neodymium Tweeter in the QXE8.2C provides numerous acoustic benefits through its 25 mm diaphragm, combined with the use of a lightweight neodymium magnet. This combination allows for high efficiency and precise high-frequency reproduction up to 24000 Hz. The soft fabric dome ensures higher acoustic resolution and avoids unwanted vibrations, making the sound crystal clear and distortion-free. With a power handling of 125 Watts RMS and a maximum power of 250 Watts, the Tweeter delivers consistent and detailed sound quality even at high volumes. The design also allows for a shallow installation depth, making the Speaker Set suitable for a variety of installation environments.

What dimensions are important for the installation of the QXE8.2C?

For the installation of the QXE8.2C Speaker Set from ESX, the following dimensions are crucial: The woofer has a cutout diameter of 182 mm and a mounting depth of only 57 mm, which increases flexibility in placement. The fabric neodymium Tweeter requires a cutout diameter of 44 mm with a minimum mounting depth of 9 mm. These small dimensions allow for the integration of the set into a variety of vehicle models without extensive modifications. The total weight of the speakers is 542 g each, making them suitable for use in lightweight and space-critical environments. However, always check the vehicle documentation or the dimensions of the installation locations to ensure compatibility.

What power can the QXE8.2C Speaker Set deliver in the car?

The QXE8.2C from ESX is capable of delivering a continuous power of 125 Watts RMS, while the maximum power reaches an impressive 250 Watts. These power values guarantee rich and dynamic audio playback, even with demanding music pieces. The speaker interacts efficiently with amplifiers due to its 3 Ω impedance, optimizing the overall sound performance. The use of fiberglass membranes combined with the neodymium magnet drive also provides increased impact and sensitivity, ensuring a precise and powerful listening experience. Especially at volumes that require high power, the difference is clearly audible.

How does the copper cap contribute to impedance linearization in the QXE8.2C?

The copper cap used in the pole core of the QXE8.2C is a technical breakthrough in impedance linearization. It helps reduce inductance fluctuations, leading to a balanced impedance across the entire frequency range. This stabilization helps reduce distortion at higher frequencies and significantly improves overall sound quality. Especially at volumes where conventional speaker systems often show uneven impedance, the QXE8.2C impresses with consistent performance. The use of copper also enhances heat dissipation, allowing the speaker to remain efficient under demanding conditions.

What materials are used for the membranes of the QXE8.2C?

The membranes of the QXE8.2C Speaker Set from ESX are made of high-quality fiberglass, which is both lightweight and stable. These materials are known for their excellent acoustic performance and low distortion potential. The fiberglass structure improves damping, preventing unnecessary resonances and creating a clear, natural sound. The durability and resistance to environmental influences such as moisture and temperature fluctuations make this material choice ideal for automotive use. This means that the speaker consistently delivers excellent performance even under demanding conditions.

How can the QXE8.2C enhance the sound experience in the car?

The QXE8.2C from ESX enhances the acoustic experience in the car through a combination of thoughtful technical features such as neodymium magnet drive and optimized crossovers. The wide frequency range of 35 Hz to 24,000 Hz allows for detailed playback of various music genres. The solid bass and clear highs create a balanced sound atmosphere that impresses both during quiet and loud playback. In particular, the precise tuning and high-quality materials of the membranes contribute to a musical performance that goes far beyond the typical speaker system. This speaker is a valuable addition, especially for audiophiles or music lovers who appreciate high-quality playback.

What role does the voice coil play in the QXE8.2C speaker?

The 30 mm voice coil of the QXE8.2C speaker from ESX is crucial for converting electrical signals into mechanical movement. Its special design, including additional ventilation, allows for effective cooling, minimizing heat stress and ensuring consistent performance even at high output. The ventilation improves thermal stability, making the speaker particularly durable and resistant to power overload. Additionally, the large coil windings ensure precise sound conversion, allowing for accurate tones without mechanical distortion. Especially when high levels and control are required, the voice coil proves to be a key element for the sound excellence of the system.
