Frequently Asked Questions about Quantum QXE8D2

What performance features does the Quantum QXE8D2 offer?

The Quantum QXE8D2 from ESX impresses with a power handling of 400 Watts RMS and a maximum power of 800 Watts. With its 64 mm dual voice coil and a robust aluminum die-cast basket, this 8-inch Subwoofer is a powerful addition to any audio system. The double-stitched surround and effective ventilation through the pole core contribute to thermal stability and high sound quality. Its impedance of 2+2 Ohms allows for flexible adjustments and configurations. The strong 126 oz. dual magnet ensures excellent sound depth, further enhanced by the Xmax of ±18 mm.

How is cooling achieved in the ESX Quantum QXE8D2?

The Quantum QXE8D2 utilizes a thoughtful ventilation design of the pole core to ensure efficient cooling. This method of air circulation helps maintain a consistently low temperature of the dual voice coil, which in turn maximizes the durability and performance of the 8-inch Subwoofer. Especially when you intend to utilize the maximum power handling of 800 Watts, the ventilation helps prevent thermal overload. The combination of the robust aluminum die-cast basket and the cooling allows for sound precision to be maintained even under intense use.

What sound quality can be expected from the Quantum QXE8D2?

With the Quantum QXE8D2 from ESX, you can expect exceptional sound depths and sonic precision enabled by the Xmax of ±18 mm. The 126 oz. dual magnet, along with the pressed paper cone and double-stitched surround, ensures a resonance-free sound reproduction. The precise construction and the 64 mm dual voice coil allow for a dynamic soundscape with deep, rich tones. Ideal for discerning listeners who appreciate both volume and clarity in their audio system and want to benefit from a power of 400 Watts RMS.

What is the installation depth of the Quantum QXE8D2 Subwoofer?

The installation depth of the Quantum QXE8D2 Subwoofer is 138 mm. This compact dimension allows for flexible integration into almost any audio system, especially in vehicles with limited space for speaker installation. Additionally, the required installation opening is 183 mm, ensuring precise fit within the specified width. Its compact design and robust aluminum construction also allow for versatile positioning, both in the trunk and as part of a custom sound system.

Which car brands and models is the Quantum QXE8D2 compatible with?

The ESX Quantum QXE8D2 is designed to easily integrate with a variety of car brands and models due to its carefully calibrated dimensions and flexible impedance of 2+2 ohms. Unfortunately, specific car brands are not explicitly listed in the product description. However, adaptability is ensured by the compact design and the specified installation dimensions – particularly the installation opening of 183 mm and the installation depth of 138 mm. This allows for easy installation in common vehicle types without requiring special modifications at the installation site.

What materials are used in the Quantum QXE8D2?

The Quantum QXE8D2 uses high-quality materials to ensure durable and powerful performance. It primarily features an aluminum die-cast basket that provides stability and longevity. The 64 mm dual voice coil is responsible for precise sound control, complemented by a double-stitched surround that enhances resonance reduction. Furthermore, the diaphragm is made of pressed paper, offering a good mix of strength and lightness, resulting in outstanding sound reproduction. The 126 oz. dual magnet supports the sound spectrum and bass performance.

Can the Quantum QXE8D2 be integrated into existing audio systems?

Yes, the Quantum QXE8D2 can be easily integrated into existing audio systems. Thanks to the 2+2 ohm impedance, it offers flexible configuration options, making it adaptable for different amplifiers and sound systems. The power output of 400 watts RMS ensures excellent sound quality even when combined with powerful systems. The compact dimensions, particularly the installation opening of 183 mm and the installation depth of 138 mm, facilitate installation in existing setups without significant structural modifications.

How is the design of the Quantum QXE8D2 Subwoofer structured?

The design of the Quantum QXE8D2 Subwoofer focuses on performance and flexibility. The aluminum die-cast basket provides the structural integrity necessary to minimize vibrations while maximizing durability. An important component of the design is the 64 mm dual voice coil, which aims for optimal frequency response. The double-stitched surround complements this design with improved cone control, while the strong 126 oz. dual magnet ensures exceptional low-frequency performance. The outer design is compact yet functional, allowing for easy integration into many sound solutions.

What type of voice coil does the Quantum QXE8D2 have?

The Quantum QXE8D2 is equipped with a 64 mm dual voice coil. This special voice coil allows for highly precise control of the Subwoofer, ensuring high-quality sound production. This construction also supports the selectable impedance of 2+2 ohms, enabling amplifier-friendly integration and ensuring compatibility with various audio equipment. The winding height of 36 mm of the voice coil offers a balance between precision in playback and durability at high volumes, creating ideal conditions for long-lasting and powerful sound results.

What role does the dual magnet play in the Quantum QXE8D2?

The 126 oz. (3.6 kg) dual magnet in the Quantum QXE8D2 plays a central role in sound reproduction by efficiently driving the voice coil. The enhanced magnetic force optimizes the mobility of the diaphragm, resulting in deeper, richer bass and improving overall sound quality. This is particularly important for consistent frequency response and strong bass performance, which audiophiles appreciate. The magnet is designed to harmonize with the robust aluminum die-cast basket and the pressed paper diaphragm to achieve superior sound performance across various audio applications and systems.
