The Quantum QXB12 subwoofer has an impedance of 2+2 ohms, which means it is designed for both series and parallel connections. This flexibility allows you to optimally match the subwoofer to your amplifier. In a series connection, the total impedance increases, while the parallel connection reduces it to the minimum, which can lead to different loading scenarios for amplifiers. The dual terminal design of the subwoofer facilitates installation and provides additional options for system customization, especially in more complex audio setups.
The Quantum QXB12 subwoofer is a 12-inch (30 cm) enclosure subwoofer. This dimension significantly contributes to the performance and efficiency of the subwoofer and allows for deeper bass reproduction at higher volumes. The size is ideal for vehicles that require powerful bass without taking up too much space in the trunk. With dimensions of 63 x 40 x 37/27 cm, it is compact enough to be installed in various car models while still providing enough volume for high-quality music playback.
The installation of the Quantum QXB12 from ESX in the vehicle requires careful consideration of the dimensions: 63 x 40 x 37/27 cm. These measurements allow for the integration of the subwoofer into a variety of vehicle types. It is important to ensure that there is sufficient space in the trunk or another suitable area. The subwoofer should be securely mounted to minimize vibrations and not compromise sound quality. Thanks to the dual terminal, connecting to an amplifier is straightforward and only requires attention to the impedance configuration to ensure optimal performance.
The Quantum QXB12 is equipped with a luxurious 4-fold protective grille that has been specially designed for this model. This grille protects the subwoofer from physical damage and preserves the delicate membrane from alienation, while simultaneously not compromising sound quality. The reinforcement provided by the protective grille helps to increase the durability and reliability of the subwoofer, especially under intense use. This feature is particularly useful for installations in vehicles, where it may be exposed to unwanted impacts and foreign objects, which is essential for protection against wear.
The Quantum QXB12 subwoofer offers flexible connection options thanks to its 2+2 ohm impedance. It can be operated with amplifiers designed for low impedances as well as those that require a higher impedance. Amplifiers capable of delivering up to 2000 watts at 4 ohms or 1000 watts RMS at 2 ohms are particularly suitable. This variability in connection provides the opportunity to perfectly match the subwoofer to many different audio setups. Both mono and multi-channel amplifiers that provide the appropriate power ratings are compatible with this subwoofer.
The 76 mm dual voice coil of the Quantum QXB12 plays a central role in the performance and sound precision of the subwoofer. This component ensures improved heat dissipation and enables the generation of deeper frequencies with greater precision. The dual voice coil supports the high load capacity of the subwoofer by allowing for distortion-free listening pleasure at maximum volume. Additionally, it increases flexibility in amplifier matching through the option of series or parallel connection. These features make the dual voice coil a crucial factor for the acoustic excellence of the subwoofer.
The Quantum QXB12 from ESX is equipped with an innovative dual terminal that offers a 2+2 Ohm impedance. This configuration allows the subwoofer to be connected both in series and in parallel. A dual terminal provides flexibility for integration into various car audio systems. It not only allows for easy adjustment of the amplifier impedance to the speaker requirements but also supports better distribution of the electrical load. This connectivity is ideal for enthusiasts seeking more control over their audio adjustments and preferring more complex audio configurations.
The special 4-fold protective grille of the Quantum QXB12 from ESX offers protection without compromising acoustic performance. This grille protects the speaker membrane and other sensitive components from physical influences and damage, which is especially important in mobile applications like in cars. It is designed not to obstruct sound flow, with the structure of the grille minimally affecting audio output. The protective grille ensures that the subwoofer remains consistent in its performance, provides extended protection against mechanical damage, and guarantees a longer lifespan for the subwoofer.

Your advantages with Masori

Quantum QXB12 by ESX: Buy powerful bass performance online

The Quantum QXB12 is a remarkable enclosure subwoofer from ESX, boasting a solid construction and impressive performance. With an RMS power handling of 1000 watts and a maximum power handling of 2000 watts, this subwoofer offers immense output power, ideal for deep and powerful bass. This performance makes it particularly suitable for demanding audio setups that require enhanced bass. The Masori Lowest Price Guarantee ensures you get the best price. The sturdy 18 mm MDF cabinet and the extra-reinforced front panel contribute to excellent resonance control, minimizing vibrations to ensure clean bass reproduction.

Integrated double terminal with flexible cabling

The Quantum QXB12 features an integrated dual terminal with an impedance of 2+2 ohms. This configuration allows for flexible cabling options, either in series or parallel, depending on your amplifier's requirements. Such cable management versatility is rare in this category, making the Quantum QXB12 an attractive option for audio systems with diverse amplifier requirements. The 2+2 ohm impedance is ideal for providing greater control over electrical resistance and can increase the efficiency of your system.

76 mm dual voice coil: More control and power

The ESX subwoofer is equipped with a 76 mm dual voice coil, allowing it to efficiently handle higher power levels. The dual voice coil increases the cone's range of motion, resulting in improved bass performance. A larger voice coil provides improved thermal and acoustic control, which is crucial for achieving full power without distortion. Units with smaller voice coils may be limited by heat generation, compromising reliability and fidelity.

Robust MDF cabinet for resonance-free playback

The solid construction of the 18 mm MDF cabinet plays a crucial role in reducing unwanted resonances. This strong cabinet structure prevents vibrations that could impair sound clarity. MDF is known for being an excellent soundproofing material, enhancing sound quality by channeling and minimizing resonant frequencies. Comparable subwoofers without this cabinet rigidity may suffer from sound distortion.

Specialized protective grille for more safety

Another standout feature is the custom-designed quadruple grille, which is both stylish and functional. It protects the subwoofer's delicate diaphragm from physical damage, which can often occur in vehicle environments. This type of protection is essential for high-performance subwoofers to extend their lifespan and ensure consistent sound reproduction. Without such a robust grille, environmental influences could degrade sound quality over time.

Subwoofer dimensions as an important installation factor

Measuring 63 x 40 x 37/27 cm, the Quantum QXB12 fits seamlessly into a wide variety of vehicle layouts. These dimensions are crucial for precise in-vehicle installation planning, as they ensure that no functionality is lost in the designated space. Never underestimate the importance of dimensions; inappropriate dimensions can lead to overheating or compromise audio quality if not installed correctly.
