Frequently Asked Questions about Access Bomba BP20

What inputs does the Access Bomba BP20 Subwoofer have?

The Access Bomba BP20 Subwoofer from Focal is equipped with high and low-level inputs to ensure flexible integration into various audio systems. The high-level inputs allow connection to the speaker outputs of a car radio, which is particularly advantageous when dedicated preamp outputs are not available. Low-level inputs, on the other hand, enable a direct connection to a preamplifier or head unit with corresponding outputs. These versatile connection options make the BP20 an excellent choice for different car audio installations without needing to alter the existing setup.

What is the frequency response of the Focal Access Bomba BP20?

The frequency response of the Focal Access Bomba BP20 ranges from 20 Hz to 125 Hz, allowing for comprehensive bass reproduction. This range covers both very low frequencies that provide powerful bass and higher bass frequencies that are relevant in many music genres. Thanks to the integrated low-pass filter, the transition to the main speakers of the audio system can be optimized to avoid overlaps or gaps in the frequency spectrum. This wide frequency range makes the Subwoofer an ideal companion for music lovers who value a rich and intense bass.

What are the dimensions of the Bomba BP20 Enclosed Subwoofer?

The Bomba BP20 Enclosed Subwoofer from Focal has dimensions of 250 mm in height, 440 mm in length, and 324 mm in width. This compact design allows for easy installation in most vehicles without taking up much space. The dimensions are optimally tuned to the acoustic properties of the subwoofer, particularly regarding its bandpass enclosure principle, which enables efficient bass reproduction. When planning the installation, the intended space in the trunk or under the seats should be checked for compatibility with these measurements to ensure a hassle-free mounting.

Is the Focal Bomba BP20 compatible with my existing speakers?

The compatibility of the Focal Bomba BP20 with existing speakers primarily depends on the nominal impedance and connection options. The Subwoofer has a nominal impedance of 4 Ohms, which corresponds to the standard of many speakers in car audio systems. With its high and low-level inputs, the BP20 allows for seamless integration into both factory-installed systems and retrofitted audio systems, without requiring special adjustments. This makes the BP20 compatible with a variety of car audio configurations and provides an excellent enhancement of bass reproduction.

What role does the low-pass filter play in the Access Bomba BP20?

The low-pass filter in the Access Bomba BP20 is essential for adjusting the range of frequencies reproduced to meet the requirements of the audio system. Specifically, the crossover frequency is set so that the Subwoofer only reproduces the intended frequencies up to 125 Hz, while higher frequencies are suppressed. This prevents the Subwoofer from taking over frequency ranges that are better covered by the main speakers. Together with the bass boost and subsonic filter, the low-pass can significantly optimize the sound character and adapt it to individual requirements.

What is the nominal and maximum power of the Focal Bomba BP20?

The Focal Bomba BP20 offers high performance with a nominal power of 150 WRMS and a maximum power of 300 Watts. The nominal power corresponds to the continuous power output that the Subwoofer can handle without distortion. This measure is important for assessing regular bass efficiency. The maximum power, on the other hand, indicates how much power the Subwoofer can process during short dynamic peaks without being damaged. These power specifications highlight the dynamic capacity of the BP20 to deliver impressive and deep sound at various volume levels.

What installation tips should be considered for the Bomba BP20?

When installing the Bomba BP20, the dimensions (250x440x324 mm) should be taken into account. The choice of installation location in the vehicle is crucial for sound performance, and the Subwoofer is typically installed in the trunk. The bandpass enclosure principle requires that the Subwoofer is correctly aligned to keep pressure loss to a minimum. It is also important to lay the power and signal cables properly to avoid interference. Correctly setting the integrated filters (low-pass, subsonic) and the phase shift function is necessary to achieve harmonization with the existing speaker system.

What filter options does the Bomba BP20 offer?

The Focal Bomba BP20 is equipped with several filter options, including a low-pass filter, subsonic filter, and a phase shift function that allow for precise fine-tuning of the sound signals. The low-pass filter restricts frequencies to the range of 20 Hz to 125 Hz. The subsonic filter protects the speaker from inaudible, very low frequencies that could be concerning for the diaphragm's movement. The phase shift option allows for adjusting the phase of the bass signal to ensure a time-aligned integration with the front speakers, which is essential for homogeneous bass integration.

How does the bass boost affect the sound reproduction of the BP20?

The bass boost in the Bomba BP20 is an audio control circuit that enhances the bass range in sound reproduction to intensify the subjective perception of low frequencies. Especially if you enjoy listening to music loudly, you can benefit from using the bass boost, as it highlights specific frequency bands, making the bass fuller and stronger, even at lower volumes. This is particularly useful in open vehicles or environments with high noise levels. The bass boost can be adjusted to optimize the sound impression according to personal preferences or the acoustic conditions of the vehicle.

What enclosure principle does the Focal Bomba BP20 use and why?

The Focal Bomba BP20 uses the bandpass enclosure principle, which is particularly suitable for maximizing sound pressure in a defined frequency range. In this construction principle, the subwoofer is housed in a double-vented enclosure that intensifies the output of low frequencies and increases efficiency by dampening disruptive frequencies outside the desired range. This design results in higher output power while maintaining the same driver size, allowing for powerful and precise bass, which is especially useful in limited installation spaces.
