Frequently Asked Questions about Quantum QXB12

What is the load capacity of the Quantum QXB12 Subwoofer?

The Quantum QXB12 Subwoofer from ESX is designed for a maximum load capacity of 2000 watts, while the RMS load capacity is 1000 watts. These values make it ideal for intense music use. The high load capacity allows for the reproduction of both subtle bass notes and powerful beats without distortion. Thanks to its robust construction and the powerful 76 mm dual voice coil, the QXB12 provides the sound stability expected from an Enclosed Subwoofer of this class. Especially if you enjoy listening to music at high volumes, this Subwoofer excels with its sustained performance.

What material is used for the housing of the Quantum QXB12?

The housing of the Quantum QXB12 from ESX is made of 18 mm thick MDF with an extra reinforced front panel. This material offers optimal stability and minimizes unwanted vibrations, leading to a clearer sound image. The robust construction is specifically designed to support the powerful output of the Subwoofer. The stable build not only protects the internal components of the Subwoofer but also provides a resilient structure that easily withstands the demands of intense audio applications. The design with logo stickers adds an aesthetic touch to the housing.

What impedance does the Quantum QXB12 have and what does that mean?

The Quantum QXB12 Subwoofer has an impedance of 2+2 ohms, which means it is designed for both series and parallel connection. 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 a minimum, which can lead to different load scenarios for Amplifiers. The dual terminal design of the Subwoofer facilitates installation and offers additional options for system customization, especially in more complex audio setups.

What size is the Quantum QXB12 Subwoofer?

The Quantum QXB12 Subwoofer is a 12-inch (30 cm) Enclosed Subwoofer. This dimension significantly contributes to the performance and efficiency of the subwoofer, allowing 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. The dimensions of 63 x 40 x 37/27 cm make it compact enough to be installed in various car models while providing enough volume for high-quality music playback.

How can the Quantum QXB12 be installed in a vehicle?

Installing the Quantum QXB12 from ESX in a 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 enough 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 terminals, connecting to an Amplifier is straightforward and only requires attention to the impedance configuration to ensure optimal performance.

What special protective features does the Quantum QXB12 have?

The Quantum QXB12 is equipped with a luxurious 4-fold protective Grille specifically designed for this model. This Grille protects the subwoofer from physical damage and keeps the delicate diaphragm safe from alienation while not compromising sound quality. The reinforcement provided by the protective Grille helps increase the durability and reliability of the subwoofer, especially under heavy 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.

Which Amplifiers can the Quantum QXB12 be operated with?

The Quantum QXB12 Subwoofer allows for flexible connection options thanks to its 2+2 Ohm impedance. It can be operated with Amplifiers designed for low impedances as well as those requiring 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 offers the possibility 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.

What role does the dual voice coil play in the Quantum QXB12?

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 enjoyable listening at maximum volume without distortion. 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 sound excellence of the Subwoofer.

What advantages does the dual terminal of the Quantum QXB12 offer?

The Quantum QXB12 from ESX is equipped with an innovative dual terminal that provides a 2+2 Ohm impedance. This configuration allows the Subwoofer to be connected both in series and in parallel. A dual terminal offers 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.

How does the protective grille affect the performance of the Quantum QXB12?

The special quadruple protective grille of the Quantum QXB12 from ESX offers protection without compromising acoustic performance. This grille protects the speaker diaphragm and other sensitive components from physical influences and damage, which is especially important in mobile applications like 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.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
