Frequent questions about ATB20P


Welche Leistung bietet der ATB20P Subwoofer von Axton?

The ATB20P subwoofer from Axton delivers an output power of 150 W RMS at 4 Ohm. The integrated Class A/B amplifier ensures stable and powerful performance, ideal for deep bass. The versatility of the input allows you to use either an RCA cinch input or a high-level input with auto turn-on, enabling effective adaptation to existing audio systems. This makes the subwoofer excellent for use in vehicles that demand powerful and deep sound without the need for a separate amplifier.

Wie beeinflussen die Passiv-Membranen den Klang des ATB20P?

The two passive membranes in the ATB20P from Axton significantly contribute to deep bass reproduction. They extend the bass response by better utilizing resonant frequencies without the need for additional active drivers. This technique allows for an increase in the efficiency and sound pressure of the subwoofer, resulting in deeper and more powerful bass. This is particularly advantageous in closed enclosures like the aluminum die-cast of the ATB20P, as it expands the bass range without requiring more energy input.

Wie wirkt sich der Frequenzgang des ATB20P auf den Bass aus?

The frequency response of the ATB20P subwoofer from Axton ranges from 25 to 150 Hz. This means that the subwoofer is specifically designed for low frequencies that traditional speakers cannot reproduce efficiently. The lowest frequency range starting at 25 Hz allows for particularly deep bass tones to be audible, while the upper range at 150 Hz ensures the transition to the main speakers. Such a bandwidth enables seamless integration into existing audio systems and ensures that the bass sounds deep and full, even at low volume.

Welche Vorteile bietet das Aluminium-Druckgussgehäuse des ATB20P?

The aluminum die-cast housing of the ATB20P from Axton offers several advantages for sound quality and durability. Aluminum has excellent thermal properties that help regulate the temperature of the built-in 150 W RMS amplifier, providing improved long-term reliability. Additionally, a die-cast housing minimizes unwanted vibrations and resonances that could affect the sound, ensuring more precise bass reproduction. At the same time, it is robust and protects the sensitive internal components from external influences. Another practical aspect is the flat design, which allows for discreet installation.

Welche Kontrollmöglichkeiten bietet der ATB20P Subwoofer?

The ATB20P from Axton offers several control options to customize the sound: A phase switch allows for switching between 0 and 180 degrees to adjust the phase between the subwoofer and main speakers. The low-pass filter is adjustable from 50 to 150 Hz to set the exact upper frequency limit. In addition to the subsonic filter at 20 Hz to protect against extremely low frequencies, a bass boost allows for an increase of 0 to 18 dB @ 45 Hz. These fine adjustments can be conveniently made using the included bass level remote control, giving you optimal control over the sound image.

Wie ist der ATB20P Subwoofer im Auto zu installieren?

The ATB20P from Axton is optimized for placement under a vehicle seat, as the controls and connections are integrated at the front of the aluminum die-cast housing. Installation is therefore space-saving and discreet. Since the housing is kept compact, you should pay attention to the exact dimensions of the installation location to ensure an optimal fit. For correct installation, the power cables are connected to the high-level or RCA input, with the auto turn-on simplifying operation by automatically turning the amplifier on and off. This ensures seamless integration.

Welche Anschlussmöglichkeiten bietet der ATB20P Subwoofer?

The ATB20P subwoofer from Axton offers versatile connection options for various audio systems in the car. It is equipped with an RCA cinch input, ideal for connecting to car radios with preamp outputs. Additionally, a high-level input is available, allowing a connection to speaker outputs, which is especially useful for factory radios without preamp outputs. The auto turn-on is another practical feature that automatically activates the subwoofer when an audio input signal is detected, ensuring easy handling without additional switches.

Wie beeinflusst der Bass-Boost die Klangqualität des ATB20P?

The bass boost of the ATB20P from Axton allows for an increase in bass levels of up to 18 dB at 45 Hz. By strategically using this function, you can adjust the bass to your personal preferences to achieve a richer sound. Especially if you enjoy music genres with intense bass lines, the boost can distinctly highlight the low frequencies without causing distortion. Control over this setting is conveniently done via the included bass level remote control, providing you with maximum flexibility in sound design.

Wie funktioniert der Phasenschalter im ATB20P Subwoofer?

The phase switch in the Axton ATB20P subwoofer allows switching between two phase positions: 0 degrees and 180 degrees. This ability to adjust the phase is crucial to ensure that the subwoofer operates in sync with the main speakers. By adjusting the phase, you can avoid phase shifts that could lead to the cancellation of bass frequencies, thus ensuring a harmonious listening experience. This function is particularly useful in complex audio systems in vehicles to ensure that all frequencies play in harmony.

Was ist der Zweck des Subsonicfilters im ATB20P Subwoofer?

The subsonic filter in the Axton ATB20P is designed to eliminate frequencies below 20 Hz, which are not audible to the human ear and often unnecessarily tax the amplifier's performance. These frequencies can stress the voice coil without contributing to the active listening experience. By using the subsonic filter, unnecessary low-frequency signals are prevented from burdening the subwoofer, which improves both the performance and lifespan of your subwoofer. This results in a clearer and more efficient bass sound, especially under heavier loads.
