Robust die-cast aluminum basket for stability and durability

The ESX Quantum QXE8D2 features a high-quality die-cast aluminum basket that not only ensures stability during operation but also minimizes vibration. This solid structure supports the subwoofer's high power handling of up to 800 watts. The aluminum basket is significantly more robust than other materials such as plastic, making it ideal for applications where durability is paramount. A weaker basket could lead to resonance issues that impair sound quality.

64 mm double voice coil with 36 mm winding height for precise frequency reproduction

The Quantum QXE8D2's dual voice coil has an impressive 64 mm diameter and a 36 mm coil height, allowing for precise control of the cone movement. This design allows even low frequencies to be reproduced clearly and with detail. Compared to subwoofers with smaller coils, the QXE8D2 offers improved efficiency and lower distortion at high volumes. A smaller voice coil would compromise precision at high and low frequencies.

Powerful 126 oz. dual magnet for powerful bass reproduction

Equipped with a remarkable 126 oz (3.6 kg) dual magnet, the ESX subwoofer delivers the outstanding magnetic force necessary for powerful bass reproduction. Strong magnets are crucial for optimizing the driving forces acting on the coil and precisely controlling the diaphragm excursion. A weaker magnet would reduce the dynamics and limit the overall volume of the system.

Pole core ventilation for effective cooling and heat dissipation

The pole core ventilation in the Quantum QXE8D2 ensures effective cooling, preventing overheating during extended operation. This feature is especially important for extending the coil's lifespan and minimizing performance degradation due to heat buildup. Without effective cooling, this could lead to a reduction in electrical performance and potential coil damage, which would inevitably affect sound quality.

Double-stitched beading for extreme resilience and durability

The surround of the ESX subwoofer is double-stitched, providing increased strength and durability. This construction prevents material fatigue and cracking that can occur with conventional surrounds. The double-stitched surround is particularly beneficial at high volumes or in challenging installation scenarios, keeping the cone stable. A simple, unreinforced design could limit power handling and increase the risk of distortion.

Xmax of +/- 18 mm for impressive sound depth and bass precision

The Xmax value of +/- 18 mm on the Quantum QXE8D2 allows for significant cone excursion, resulting in improved bass reproduction. The greater the excursion, the better the subwoofer can handle low frequencies. A lower Xmax would limit the ability to produce powerful bass, which could severely impair sound quality when listening to bass-heavy music.

Flexibility through 2+2 Ohm dual voice coil for versatile configurations

Thanks to its dual voice coil design with 2+2 ohm impedance, the Quantum QXE8D2 is versatile and can be flexibly adapted to different amplifiers. This flexibility allows parallel or series connection to vary the overall system impedance. Compared to fixed-impedance subwoofers, this allows for broader compatibility and adaptability to the specific requirements of the sound system.

Subwoofer dimensions and installation options for perfect integration

With a mounting depth of 138 mm and a mounting opening of 183 mm, the Quantum QXE8D2 fits into most vehicle configurations. These compact dimensions make it particularly suitable for vehicles with limited space. Optimal adaptation to the installation space can affect bass reflection and acoustics, so precise installation is important. Inappropriate mounting dimensions could cause vibrations and significantly limit the subwoofer's optimal operation.
