Frequent questions about Quantum Q208A

Wie unterscheidet sich der Quantum Q208A von seinem Vorgängermodell?

The Quantum Q208A from ESX offers 150 watts RMS through an integrated Class A/B amplifier, representing a 50% power increase compared to its predecessor model. This increase in amplifier power significantly improves bass signal output. Also characteristic is the robust housing with passive woofers on both sides, which creates a powerful bass foundation despite compact dimensions. In addition to power, the Q208A offers useful features such as the auto turn-on function, a bass remote control, and a fixed subsonic filter set at 20 Hz, which enhance not only comfort but also sound quality.

Welche Einbauabmessungen hat der ESX Quantum Q208A?

The ESX Quantum Q208A measures 249 x 78 x 346 mm, making it ideal for installation under many vehicle seats. The compact aluminum housing allows for easy placement without intrusive installations. However, the available space should be measured precisely to ensure that there is enough ventilation space to prevent the amplifier from overheating. Its placement should be chosen to provide easily accessible RCA and high-level inputs, which are necessary for a clean connection. This compactness is particularly advantageous for tight vehicle spaces.

Welche Vorteile bieten die passiven Tieftöner des Quantum Q208A?

The passive woofers of the Quantum Q208A on both sides of the enclosure expand the bass foundation through passive resonance. This technique enhances bass performance without requiring additional power consumption. The advantage lies in a more efficient bass amplification with the same enclosure size. Protected by stable metal covers, the woofers are safe from damage in the vehicle, contributing to greater longevity. The passive technology allows the subwoofer to produce low frequencies that are more difficult to achieve with an active system alone. This technology thus improves the overall sound in the vehicle.

Wie wird die Bassleistung des ESX Quantum Q208A optimiert?

The bass performance of the ESX Quantum Q208A is optimized by features such as bass boost and the subsonic filter. The bass boost can be adjusted from 0 to 18 dB at 45 Hz to support individual listening preferences. The subsonic filter is optimized at a fixed setting of 20 Hz to eliminate unnecessary frequencies, thereby amplifying only relevant bass sounds. With the integrated bass remote control, the listener can dynamically adjust the bass level. These technological adjustments allow for the reproduction of clear, intense bass that is tailored to the acoustics of the vehicle.

Ist der Quantum Q208A mit bereits vorhandenen Audiosystemen kompatibel?

The Quantum Q208A is compatible with numerous audio systems due to its high and low level inputs. Its RCA and high level inputs allow connection to a variety of car radios, even if only a factory radio is installed. The automatic power-on feature ensures that the subwoofer integrates seamlessly into existing systems without requiring additional activation. As long as the vehicle's audio system has high or low level outputs, the subwoofer can be incorporated. The design and technologies of the Q208A thus support flexible adaptation to various audio system configurations.

Welche Rolle spielt der Class-A/B-Verstärker im Quantum Q208A?

The integrated Class A/B amplifier in the Quantum Q208A offers 150 watts RMS power and ensures improved acoustic performance. Class A/B combines the advantages of Class A and Class B amplifiers by uniting linear power with low distortion and improved efficiency. This increase in efficiency minimizes energy consumption in the vehicle battery system. The amplifier allows the subwoofer to reproduce deep tones clearly and powerfully. The quality and reliability of the Class A/B design are essential for a dynamic and detailed sound, especially for bass-heavy music content that is in demand in the automotive sector.

Wie unterstützt die Bass-Fernbedienung den ESX Quantum Q208A?

The bass remote control of the ESX Quantum Q208A allows the driver to conveniently adjust the bass intensity via hand control. This control is used for fine-tuning the subwoofer while driving, without the need for physical changes to the device. Especially when you listen to different music styles, this feature is essential to adapt the bass to individual preferences. The remote control provides direct influence on the bass amplification and can significantly affect the sound character of playback in the vehicle. Position the remote control within reach of the driver's seat for an optimal user experience.

Welche Funktionen bietet die automatische Einschaltfunktion des Q208A?

The automatic power-on feature of the Quantum Q208A activates the subwoofer as soon as an audio signal is detected. It simplifies the installation process, as no additional control line is required. This feature ensures a hassle-free start of the subwoofer, allowing it to operate without manual switching. It reduces energy consumption, as the subwoofer is only active when music is actually being played. This automation is designed for fans of comfort solutions who appreciate easy and reliable integration into the vehicle audio system without having to worry about additional power-on scenarios.

Wie beeinflusst der fest eingestellte Subsonic-Filter des Quantum Q208A den Klang?

The subsonic filter of the Quantum Q208A is fixed at 20 Hz and plays a central role in protecting the subwoofer from harmful low frequencies. By filtering out these very low frequencies, it prevents the amplifier from expending unnecessary energy to amplify sounds that are barely audible to the human ear. This improves the efficiency of the subwoofer and optimizes sound clarity by only amplifying relevant frequencies. Especially in music pieces with intense deep bass passages, the subsonic filter allows for clearer, more precise sound reproduction without distortion.

Welche Phasenverschiebungseinstellungen bietet der Quantum Q208A?

The Quantum Q208A offers two phase shift settings: 0° and 180°. These settings are crucial for correctly synchronizing the subwoofer with the rest of the audio system. Phase adjustment may be necessary if the subwoofer produces slightly delayed bass sounds due to its placement. By toggling between the phases, the user can choose the setting with the best sound coherence. For example, a 180° shift can help avoid phase issues that may arise from the placement of the subwoofer in the rear passenger compartment. Correcting this phase position contributes to clearer playback.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
