Frequent questions about ATB20A

Wie beeinflusst die konkave Membrangeometrie des ATB20A die Klangqualität?

The concave membrane geometry of the Axton ATB20A allows for high stiffness of the membrane, which ensures precise and powerful bass. This design improves sound reproduction by minimizing distortion and making bass playback clearer. Furthermore, the durable surface of the high-strength structural paint contributes to longevity and protects against damage from vibrations. Especially when you listen to music with intense bass, the concave structure ensures coherent bass reproduction even at high volumes. Thus, the overall sound experience becomes fuller and more dynamic, which is an essential advantage when installed in vehicles.

Welche Vorteile bietet das Class-D Verstärkermodul mit 100 W RMS?

The Class-D amplifier module in the ATB20A from Axton provides an impressive output of 100 W RMS, which ensures efficient and powerful sound amplification. Class-D amplifiers are known for their high energy efficiency, resulting in lower energy consumption and thus less heat generation. This keeps the system stable even at higher volumes without overheating. The 100 W RMS output is sufficient to produce a strong and clear bass in various types of vehicles, positively affecting the overall audio quality.

Wie kann der variable Tiefpassfilter des ATB20A optimal eingestellt werden?

The variable low-pass filter of the Axton ATB20A allows for flexible adjustment of the frequency response between 50 and 150 Hz with a slope of 12 dB/octave. By adjusting the crossover frequency according to your listening habits or the acoustics in the vehicle, you can precisely control the bass. For example, a lower crossover frequency can extend the bass range and allow for smoother transitions to the mid-tones. When the subwoofer is placed in a room that tends to resonate, a higher value can help avoid unwanted bass emphasis. This adaptability makes the ATB20A universally applicable.

Welche Bedeutung hat der Bass-Boost im Subwoofer ATB20A?

The bass boost on the Axton ATB20A allows for the amplification of low frequencies between 0 dB and 12 dB. With this feature, you can specifically enhance certain frequency ranges to increase the bass volume, which is particularly beneficial for music genres with sustained bass notes. These adjustments can be tailored directly to your personal listening preferences or the specific acoustic conditions of your vehicle. For example, a setting of 12 dB increases the presence and intensity of the lowest tones, providing noticeable depth and power. Thus, the bass boost significantly expands the flexibility of the ATB20A.

Welche Funktion hat der Phase Shift beim ATB20A Subwoofer?

The phase shift function of the Axton ATB20A offers two settings: 0 and 180 degrees. By adjusting the phase, you can align the sound produced by the subwoofer phase-accurately with the speakers in the vehicle. This improves overall sound quality, as a correct phase alignment makes bass reproduction appear coherent and strong. For example, you can compensate for phase issues or room modes that lead to a reduction in bass levels by changing the phase to counteract or enhance certain frequencies. The phase shift setting is a useful tool for fine-tuning the sound system.

Welche Abmessungen hat der ATB20A Subwoofer und wie wirken sie sich auf die Installation aus?

The Axton ATB20A measures 315 x 275 x 330 mm, a compact design that makes it ideal for installation in various vehicles. Thanks to the slanted rear wall, the subwoofer can be easily installed even in tight spaces. If you have a vehicle with limited trunk space, it is still possible to accommodate the ATB20A without losing too much cargo area. The space-saving dimensions allow for flexible integration behind seats or along the side wall, which is a significant advantage for small cars and those with unconventional geometries.

Wie funktioniert die Auto Turn-On Funktion des ATB20A?

The Auto Turn-On function of the Axton ATB20A is activated via the high-level inputs. This function allows the subwoofer to turn on automatically as soon as an audio signal is detected. It simplifies installation since no separate remote cable is needed to power the device on. This feature is particularly advantageous in older vehicles without a specific subwoofer output, as it allows for seamless integration into existing systems. Don't forget to connect this function correctly to ensure flawless functionality. This significantly enhances user comfort.

Welche technischen Spezifikationen beeinflussen die Frequenzeinstellungen des ATB20A?

The frequency response of the Axton ATB20A is specified at 45 - 150 Hz, ensuring impressive deep bass performance. This specification provides insight into the range of low frequencies that the subwoofer can articulate, making it ideally suited to the sound signature of many music tracks. Consistency in the reproduction of this frequency range is crucial for the experience of a full and dynamic car sound. The use of a variable low-pass filter and bass boost provides additional control over the efficient utilization of these specifications to create a sound profile tailored to individual preferences.

Wie trägt die Basspegelfernbedienung zur Nutzererfahrung beim ATB20A bei?

The included bass level remote control of the Axton ATB20A offers the ability to adjust the bass level directly and conveniently from the driver's seat, without having to physically go to the subwoofer. This significantly increases user-friendliness, as a quick adjustment of the bass volume can be made depending on the song or personal taste. For example, while driving on different road surfaces, the bass intensity can be minimized to reduce disturbing vibrations. This practical feature allows for dynamic music adjustment, which is particularly advantageous in changing driving conditions.

Ist der ATB20A Subwoofer kompatibel mit gängigen Fahrzeugmodellen?

The Axton ATB20A is compatible with many common vehicle models, especially thanks to its compact dimensions of 315 x 275 x 330 mm. These measurements allow the subwoofer to be integrated into a variety of vehicle types, whether in sedans, station wagons, or SUVs. Its angled rear panel supports fitting in particularly tight spaces such as behind the rear seats or in small trunks. The universal high-level inputs allow for installation in both older and more modern models, while the auto turn-on function increases convenience when integrating into existing sound systems.

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!
