Frequently Asked Questions about ATB20P

What power does the ATB20P Subwoofer from Axton provide?

The ATB20P Subwoofer from Axton delivers an output power of 150 Watts RMS at 4 Ohms. 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 line 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 impactful and deep sound without the need for a separate amplifier.

How do the passive radiators affect the sound of the ATB20P?

The two passive radiators in the ATB20P from Axton significantly contribute to deep bass reproduction. They enhance bass output by better utilizing resonant frequencies without the need for additional active drivers. This technique allows for increased efficiency and sound pressure of the subwoofer, giving you deeper and more powerful bass. This is particularly beneficial in sealed enclosures like the aluminum die-cast of the ATB20P, as it expands the bass range without requiring more power input.

How does the frequency response of the ATB20P affect the bass?

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.

What advantages does the aluminum die-cast housing of the ATB20P offer?

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 Watt 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.

What control options does the ATB20P Subwoofer offer?

The ATB20P from Axton provides several control options to customize the sound: A phase switch allows toggling 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 profile.

How is the ATB20P Subwoofer installed in the car?

The ATB20P from Axton is optimized for placement under a vehicle seat, as controls and connections are integrated at the front of the aluminum die-cast housing. Installation is thus space-saving and discreet. Since the housing is kept compact, you should pay attention to the exact dimensions of the installation location to ensure a proper fit. For correct installation, the Power Cable is 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.

What connection options does the ATB20P Subwoofer offer?

The Axton ATB20P Subwoofer offers versatile connection options for various audio systems in the car. It is equipped with an RCA 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.

How does the bass boost affect the sound quality of the ATB20P?

The bass boost of the Axton ATB20P allows for an increase in bass level of up to 18 dB at 45 Hz. By using this feature, 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.

How does the phase switch work in the 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 works in sync with the main speakers. By adjusting the phase, you can avoid phase shifts that could lead to cancellation of bass frequencies, thus ensuring a harmonious listening experience. This function is particularly useful in complex audio systems in the vehicle to ensure that all frequencies play in harmony.

What is the purpose of the subsonic filter in the 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, improving both the performance and lifespan of your subwoofer. This results in a clearer and more efficient bass sound, especially under heavier loads.
