Frequently Asked Questions about Quantum QXE52


What technical features does the Quantum QXE52 have?

The Quantum QXE52 from ESX is a 5" (13 cm) 2-way coaxial speaker with a nominal power of 80/160 Watts RMS/Max. The impedance is 4 Ω, making it suitable for a variety of amplifiers. The frequency range extends from 62 to 22,000 Hz, ideal for a dynamic sound spectrum. The speaker is equipped with 25 mm voice coils and a 12.96 oz. magnet driver. The 20 mm silk dome neodymium tweeter ensures clear highs. It has a mounting depth of 54 mm and a mounting diameter of 115 mm, making it compact and versatile.

How does the polypropylene-carbon membrane affect the sound of the Quantum QXE52?

The innovative polypropylene-carbon composite membrane of the Quantum QXE52 provides high stiffness while being lightweight. This allows for precise sound reproduction with minimal distortion. The membrane materials combine flexibility and damping, ensuring outstanding control over the mid and low frequencies. Especially if you enjoy listening to music at high volumes, you will benefit from the clarity and durability of the materials, which ensure even sound distribution. The interplay of the materials helps to create a dynamic and vibrant sound character and accurately reproduce the desired frequencies.

What advantages do the 25 mm voice coils of the Quantum QXE52 offer?

The 25 mm voice coils of the Quantum QXE52 enable excellent performance and heat resistance, which is particularly important at high volumes and during extended use. Voice coils of this size can handle more electrical power, resulting in a more powerful and dynamic sound. Additionally, they contribute to improving the thermal stability of the speaker by efficiently dissipating heat. These attributes are crucial for optimizing the speaker's durability and ensuring consistent sound quality without compromise—even under intense use.

How do you install the Quantum QXE52?

The installation of the Quantum QXE52 is quite straightforward due to its compact design with a mounting depth of 54 mm and a mounting diameter of 115 mm. Make sure to have enough space in the vehicle to optimally distribute the sound within the interior. The speaker can be mounted in standard speaker cutouts, with the included protective grille safeguarding the speaker from mechanical influences. To ensure proper performance and function, the speaker cable should be connected correctly. The low installation effort makes the Quantum QXE52 particularly user-friendly.

What sound advantages does the 20 mm silk dome neodymium tweeter of the Quantum QXE52 offer?

The 20 mm silk dome neodymium tweeter of the Quantum QXE52 is specifically designed to reproduce clear and brilliant highs. The combination of silk dome and neodymium magnet allows for precise high-frequency reproduction with high sensitivity. Especially in complex musical pieces, small details become clearly audible, leading to an overall more precise sound image. The lightweight neodymium magnet keeps the design compact, while its high magnetic energy provides efficient driving force. This results in a dynamic and evenly distributed high-frequency range. These characteristics come together to create a balanced and refined listening experience.

What frequency range does the Quantum QXE52 cover?

The Quantum QXE52 covers an impressive frequency range of 62 - 22,000 Hz, allowing it to reproduce a particularly wide sound spectrum. This means that both deep bass and high tones are clearly and detailed audible, benefiting a comprehensive listening experience. The reproduction of this bandwidth is ideal for all music genres and allows for the full exploitation of the fine nuances and dynamics of the music. The broader frequency coverage makes the speaker versatile, as it delivers great results in both standard and high-quality sound systems.

How effective is the magnetic driver of the Quantum QXE52?

The 12.96 oz. magnet driver of the ESX Quantum QXE52 is designed for maximum effectiveness by creating an optimal balance between size and performance. Magnet technology plays a crucial role in sound quality as it controls the movements of the diaphragm. With its strong magnetic force, the driver is able to keep the diaphragm in precise movements, minimizing sound distortion and producing a powerful bass. The construction allows for quick response and many details in the sound image, making the speaker a robust and high-performance choice for discerning listeners.

What wattages does the Quantum QXE52 deliver in RMS and peak?

The Quantum QXE52 offers a rated power of 80 watts in the RMS range, which means it is designed for a constant power draw while delivering stable sound quality. In the peak range, it can handle up to 160 watts, making it capable of covering short power spikes without damage. These watt ranges give the speaker the flexibility to reproduce clear and detailed sound in both conventional and more powerful sound systems. The balance between RMS and peak power ensures that the speaker performs perfectly under various conditions and delivers clear performance.

Is the Quantum QXE52 compatible with my vehicle?

The Quantum QXE52 has a mounting depth of 54 mm and a mounting diameter of 115 mm, making it suitable for installation in a variety of vehicles. It is essential to measure the available spaces in the vehicle to ensure compatibility, as these parameters are industry-standard measurements that often align with standard cutouts. Furthermore, you can check if the installation location has enough space for the included protective grille. The universal size of the Quantum QXE52 adapts well to the standard construction specifications of most automotive manufacturers.

What is the function of the protective grille on the Quantum QXE52?

The protective grille of the Quantum QXE52 serves as physical protection for the diaphragm and tweeter against mechanical damage, dust, and other environmental influences. Especially in busy vehicle interiors or installations where the speakers are mounted unprotected, this grille provides an additional safety aspect. Additionally, the cover helps to harmonize the setup style and offers a more professional appearance. The use of the protective grille has no negative impact on sound quality, as it is designed to allow sound waves to pass through without significant obstacles.
