Frequently Asked Questions about ATB20P

How much power does the Axton ATB20P Subwoofer deliver?

The Axton ATB20P Subwoofer shines with an impressive output power. At 4 Ohm, it achieves 150 Watts RMS, which is more than sufficient for most applications. The integrated Class A/B Amplifier ensures high energy efficiency and reduced heat generation. This power not only allows for powerful bass reproduction but also dynamic music playback. Especially if you enjoy listening to loud music or prefer bass-heavy tracks, the ATB20P with its 150 Watts RMS provides a solid foundation for an intense sound experience. Thanks to its intelligent placement in the aluminum die-cast housing, disturbing vibrations are additionally minimized.

What frequency ranges does the ATB20P cover?

The frequency response of the Axton ATB20P ranges from 25 to 150 Hz, covering a wide spectrum in the low-frequency range. This allows for precise and powerful reproduction of deep bass frequencies. The lower frequency range starting from 25 Hz is particularly impressive for a bass reflex system of this size. This means you can make both deep sub-bass frequencies and higher bass lines cleanly and precisely audible. The use of two passive membranes complements the performance potential and ensures improved bass reproduction. This is especially advantageous if you are looking for substantial yet well-balanced bass.

How can the Axton ATB20P be integrated into a car?

Integrating the Axton ATB20P into a vehicle is straightforward thanks to its thoughtful architecture. The subwoofer measures 203.2 mm (8 inches) and is housed in an aluminum die-cast enclosure that offers high strength with low weight. The mounting on the front of the enclosure is functional, making all controls and connections easily accessible. The RCA cinch input and the high-level input with auto-turn-on function provide flexible connection options, regardless of whether you are working with an existing car radio or an amplifier system. Note that there must be sufficient space in the vehicle for the enclosure to achieve optimal sound results.

What filter options does the Axton ATB20P offer?

The Axton ATB20P Subwoofer offers versatile filter options that allow you to tailor the sound specifically to your preferences. It is equipped with a low-pass filter with a frequency adjustment range between 50 and 150 Hz. This allows you to filter out unwanted high frequencies and focus on the bass frequencies. The integrated subsonic filter, set at 20 Hz, protects the subwoofer from distortion caused by ultra-low frequencies that cannot be reproduced. Additionally, you can adjust the bass boost; from 0 to 18 dB at 45 Hz. This is particularly advantageous for bass-intensive music genres.

What connection options are available on the Axton ATB20P?

The Axton ATB20P features several connection options that allow for flexible integration into existing audio systems. The subwoofer is equipped with an RCA input, which enables easy connection to the car radio. Additionally, there is a high-level input with an auto-turn-on function, which is particularly useful if your audio system does not have a dedicated subwoofer output. This automatic activation feature greatly simplifies installation and ensures that the subwoofer only operates when needed. The positioning of the connections on the front makes access and adjustments during operation easier.

How does the enclosure design of the ATB20P affect sound quality?

The Axton ATB20P Subwoofer is housed in a robust aluminum die-cast enclosure, which offers several advantages. The choice of this material is not random; it is characterized by high strength and durability while keeping the weight minimal. These properties are crucial for minimizing resonances and vibrations that could negatively affect sound quality. The enclosure is designed to optimally utilize bass pressure and reproduce frequencies clearly and without distortion. Especially in a car, where vehicle vibrations can be transmitted to the enclosure, such a stable construction is a significant advantage.

How does the phase switch affect the sound of the Axton ATB20P?

The phase switch on the Axton ATB20P allows you to change the phase of the Subwoofer between 0° and 180°. This is an essential tool for optimizing the integration of the Subwoofer into the existing sound system of the vehicle. For example, if you notice that the bass sounds unbalanced at certain positions in the car, there may be a phase issue. The switch helps to resolve such problems by adjusting the phase to better align the bass reproduction with the speakers, thus avoiding standing waves. This leads to a more coherent and balanced sound reproduction inside the vehicle.

What advantages do the passive membranes in the Axton ATB20P offer?

The two passive membranes built into the Axton ATB20P significantly improve bass reproduction. They act as bass reflex support without the need for a traditional bass reflex port. These membranes utilize the air pressure generated by the active driver to produce sound waves themselves, enhancing efficiency and bass reproduction, especially in the lower frequency range. This is particularly advantageous as it allows for deeper bass reproduction without the need to increase the enclosure volume. Especially in compact installations, as is often the case in vehicles, passive membranes offer significant benefits in terms of sound quality and efficiency.

What possibilities does the bass boost of the ATB20P open up?

The bass boost of the Axton ATB20P can be adjusted in a range from 0 to 18 dB at 45 Hz. This feature is particularly useful for enhancing the bass level according to your personal listening preferences. For example, if you often listen to bass-heavy music or if the bass in your vehicle is not strong enough due to acoustic issues, you can fine-tune the boost to maximize bass reproduction. The range of 45 Hz is well chosen as it corresponds to a large part of the musical bass range, thus promoting a balanced sound reproduction without overpowering other frequency ranges.

How is the Axton ATB20P controlled and what advantages does the remote control offer?

The Axton ATB20P is controlled by an included bass level remote control, which provides you with the convenience of adjusting the bass level at any time without having to change the actual controls on the Subwoofer. This remote control is particularly useful while driving, as you can quickly adjust the bass for different music tracks or preferences. Whether you want to boost or reduce the bass, the remote control allows for flexible adjustments from the cockpit. This ability to control the bass directly increases user-friendliness and enables a personalized sound experience in the car, tailored to the environment and musical mood.
