Frequently Asked Questions about Quantum QS-TWO

What power does the Quantum QS-TWO from ESX offer at different impedances?

The Quantum QS-TWO from ESX provides impressive power ratings at different impedances. At an impedance of 2 ohms, it reaches an RMS power of 2 x 95 watts, while at an impedance of 4 ohms, it offers 2 x 52 watts RMS. In bridged mode at 4 ohms, it even delivers 1 x 190 watts RMS. This flexibility makes it ideal for various speaker systems and highlights its suitability for demanding audio applications. Its compact design and high efficiency of up to 90% also make it particularly energy-efficient, relieving the vehicle's electrical system.

How do the dimensions of the Quantum QS-TWO differ from previous models?

The Quantum QS-TWO is 30% smaller than the previous model, with dimensions of only 70 x 35 x 90 mm. This compact size allows for easy integration into most vehicle interiors without taking up valuable space. Despite its small format, the amplifier offers remarkable performance data and is capable of delivering high RMS power. Use these compact dimensions to your advantage for flexible installation options – even in limited vehicle spaces, it is an ideal companion for high-quality sound systems.

What features does the Quantum QS-TWO amplifier offer in terms of sound quality?

The Quantum QS-TWO from ESX impresses with sound quality, particularly enhanced by a frequency response of 10 Hz to 60 kHz, which improves both standard audio and HD audio applications. Its ultra-low total harmonic distortion THD+N of less than 0.007% at 5W/RMS minimizes distortion, allowing it to reproduce even fine sound details accurately. With an impressive efficiency of up to 90%, it handles deep tones, ensuring excellent music playback. Especially for music lovers who value crystal-clear sound, this 2-channel amplifier offers a convincing performance.

What connection options does the Quantum QS-TWO amplifier offer?

The Quantum QS-TWO from ESX makes it easy for you to connect to various systems through its diverse options. It features high-level inputs with EPS and an automatic power-on function, making it particularly straightforward to connect to factory audio systems. You can also easily control low-frequency Subwoofers via the 2-channel RCA Line Out. The switchable high-pass and low-pass filters at 80 Hz additionally allow you to further optimize the sound. Use these features to effectively integrate the Amplifier into your existing audio system.

What does the high efficiency of up to 90% mean for the Quantum QS-TWO?

A high efficiency of up to 90% in the Quantum QS-TWO from ESX means that the Amplifier converts the energy it consumes into power extremely efficiently. This not only saves energy but also reduces heat generation and significantly relieves your vehicle's electrical system. Especially in modern vehicles with sensitive electrical systems, such an efficient device can be advantageous as it treats the vehicle battery more gently while still providing strong audio playback performance. The miniaturization and low energy consumption make the Amplifier the ideal choice for efficient car Hi-Fi applications.

What filter functions are integrated into the Quantum QS-TWO?

The Quantum QS-TWO from ESX is equipped with switchable filter functions: a high-pass filter and a low-pass filter, both operating at 80 Hz. These functions allow you to specifically adjust the frequency range and filter out unwanted frequencies. This is particularly useful when you want to tailor the sound to your speaker system or specific acoustic preferences. For example, you can suppress disturbing bass frequencies with small speakers using the high-pass filter. The precise tuning provided by these filter options makes the device particularly versatile.

How does the THD+N value affect the sound quality of the Quantum QS-TWO?

The THD+N value (Total Harmonic Distortion plus Noise) of the Quantum QS-TWO from ESX is below 0.007% at 5W/RMS, indicating an extremely clear sound reproduction. A low THD+N value means that there are only very slight distortions and interferences in the audio signal, resulting in music being reproduced with extreme detail and clarity. This is especially important for audiophiles who value the highest sound precision, as there is almost no audible loss of quality. This technical finesse is a standout feature of this Class D Nano Digital Amplifier.

Is the Quantum QS-TWO compatible with all vehicle models?

The Quantum QS-TWO from ESX is compatible with most vehicle models due to its compact dimensions and universal connectivity options. The integrated high-level inputs with EPS and the automatic turn-on feature make it particularly easy to connect. However, if you want to install it in older or particularly compact vehicle models, check the installation options based on the dimensions of 70 x 35 x 90 mm. This small size makes it easier to place under seats or in the trunk. Compatibility depends less on the car brand and more on available space and connection options.

How can the Quantum QS-TWO be installed in the car?

Installing the Quantum QS-TWO from ESX in the car is relatively simple due to its compact structure and versatile connection options. First, it is necessary to choose the ideal placement with the dimensions of 70 x 35 x 90 mm, such as under the seat or in the trunk. The high-level inputs are designed for seamless integration into existing system interfaces. Make sure the wiring is done properly to ensure optimal signal flow. The easily accessible ISO wiring harness simplifies the job, especially in conjunction with modern audio systems.

What features make the Quantum QS-TWO particularly suitable for HD Audio?

The Quantum QS-TWO from ESX is ideal for HD Audio due to its wide frequency response of 10 Hz to 60 kHz and low distortion. The exceptionally low THD+N value of under 0.007% ensures that even fine details are reproduced clearly and without distortion. Additionally, the ability to switch high-pass and low-pass filters at 80 Hz provides further flexibility for fine-tuning. The compact design and efficiency of up to 90% also contribute to outstanding audio playback, making this amplifier the preferred choice for audiophiles seeking excellent sound quality with high efficiency.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
