Built-in audiophile components and a massive aluminum heat sink ensure optimal sound quality and heat dissipation. The error protection system of the high-level inputs guarantees trouble-free operation. It features a MOSFET-PWM power supply and a triple protection circuit, maximizing both efficiency and safety. With these features, it is an excellent addition to any car audio system.

How does the bass adjustment work on the Quantum QL500.1?

The ESX Quantum QL500.1 offers precise bass control through a compact cable remote, allowing easy adjustment of the bass level. Additionally, there is a subsonic filter from 10-40 Hz and a low-pass filter from 40-150 Hz to eliminate unwanted frequencies. The bass boost is adjustable between 0-18 dB, allowing for finely tuned bass reproduction. The phase shift range of 0-180 degrees helps optimize timing and performance, ensuring a clean integration into the existing system, especially when using Subwoofers.

What protection mechanisms are integrated into the Quantum QL500.1?

The ESX Quantum QL500.1 is equipped with a triple protection circuit that protects against overheating, overcurrent, and short circuits. This is supported by a solid MOSFET-PWM power supply that ensures stable power delivery. The protection mechanisms are crucial for the longevity of the amplifier, as they prevent damage from electrical anomalies. Additionally, the audiophile-tuned components provide natural sound reproduction, and the error protection system of the high-level inputs ensures trouble-free signal processing, enhancing the overall experience.

What is the efficiency of the ESX Quantum QL500.1?

The efficiency of the ESX Quantum QL500.1 is impressively up to 93%. This high efficiency results from the advanced Class D technology, which ensures minimal energy waste and maximum power output. In practical operation, this means less heat generation, allowing the amplifier to have a longer lifespan and reliable performance even under high loads. The combination of low heat generation and energy-efficient design makes it an optimal choice for users who value performance while saving energy.

What installation options does the ESX Quantum QL500.1 offer?

With its dimensions of 226 x 43 x 120 mm, the ESX Quantum QL500.1 is specifically designed for limited installation spaces. Despite its compact size, there is no need to compromise on performance. It fits into most standard installation spaces in vehicles, with positioning remaining flexible due to its emission-free and efficient technology. Installation can be made straightforward, as the amplifier is not only lightweight but also robust with heavy aluminum die-cast side panels. Perfect for hidden installation in challenging space conditions.

How do the audiophile components of the Quantum QL500.1 affect the sound?

The audiophile-tuned components of the ESX Quantum QL500.1 ensure outstanding sound quality. They enable precise and distortion-free sound reproduction, detailing even the finest nuances in music. These components have been selectively chosen to achieve the highest fidelity, making the amplifier ideal for use in high-end audio systems. Especially for music lovers who place a high value on details and clarity, this amplifier offers a refined combination of power and sound neutrality. It provides a listening experience that goes far beyond the standard.

What frequency ranges does the ESX Quantum QL500.1 cover?

The ESX Quantum QL500.1 covers different frequency ranges that optimize specific applications in the sound setup. With a subsonic filter covering frequencies from 10 to 40 Hz, very low bass frequencies are specifically filtered to avoid unwanted resonant vibrations. The low-pass filter offers a range from 40 to 150 Hz, important for precisely adjusting bass reproduction to personal preferences or structural vehicle characteristics. These settings allow for optimal sound setup in different listening environments while also protecting the amplifier itself.

Is the ESX Quantum QL500.1 compatible with modern cars?

Yes, the ESX Quantum QL500.1 is compatible with modern cars, especially due to the 'Auto Turn-On' feature and 'Start/Stop Ready' function, which enable seamless use in new vehicle electrical systems.

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.
