Frequent Questions about Dieci DBA 201 F

What is the output power of the Dieci DBA 201 F?

The Dieci DBA 201 F from Hertz offers a maximum RMS output power of 220 watts at a supply voltage of 14.4 VDC and a distortion of less than 1% THD. This power rating indicates the Subwoofer's ability to produce consistent and clear bass reproduction during continuous operation. The use of a high-flux ferrite magnet and a large voice coil with a diameter of 38.6 mm ensures powerful and dynamic bass output. This power can be fully utilized, especially during intense musical passages or deep bass notes.

What size and design does the Dieci DBA 201 F have?

The Dieci DBA 201 F features a compact and super-slim design with a sealed enclosure and a driver size of 8 inches (20 cm). The precise dimensions of 345 mm in width, 245 mm in depth, and a height of only 79 mm allow for easy integration into vehicle environments with limited space. This design is ideal for achieving maximum Subwoofer performance without taking up valuable interior space. The flat construction ensures that the Subwoofer remains unobtrusive while still delivering powerful bass. This design is optimal for a variety of automotive installations.

How can the bass reproduction of the Dieci DBA 201 F be optimized?

The Dieci DBA 201 F offers advanced controls for fine-tuning bass reproduction. The integrated 24 dB/octave low-pass crossover filters frequencies and allows adjustments between 50 and 150 Hz, while the bass boost in the range of 0 to 6 dB at 45 Hz gives users the ability to tailor sound settings to personal preferences. The phase switch with 0/180° enables precise tuning of the phase alignment with the main speaker system, which is essential for sound integration. The subsonic filter protects the diaphragm with a fixed setting of 15 Hz to avoid excessive diaphragm excursion.

How does the automatic power-on function of the Dieci DBA 201 F work?

The automatic power-on function of the Dieci DBA 201 F is based on a built-in audio-sense circuit that activates the Subwoofer upon detecting an input signal. When the signal is lost, the Subwoofer automatically switches to standby mode to save energy when not in use. This function eliminates the need for additional manual activation. Alternatively, a remote power-on cable can be used to disable the automation. This technical solution ensures that the Subwoofer is only active when it is actually needed, promoting sustainable efficiency.

What frequency response range does the Dieci DBA 201 F offer?

The Dieci DBA 201 F features a comprehensive frequency response between 32 Hz and 400 Hz, providing precise bass reproduction without missing critical frequency ranges. The frequency range is optimized by the combination of a sealed active enclosure and the strong 38.6 mm voice coil made of copper. This promises to deliver both precise low frequencies and the necessary power clarity. The frequency response bandwidth ensures that the Subwoofer maintains its brilliant precision and impressive stage presence even when reproducing demanding genres like dubstep or orchestral works.

What input signals does the Dieci DBA 201 F accept?

The Dieci DBA 201 F accepts both PRE and SPK input signals. The PRE input signals range from 0.2 to 5 VRMS, while SPK input signals are supported from 1.2 to 30 VRMS. This adjustment tolerance allows for seamless integration into various audio systems, whether they are factory-made or custom. The PRE input has been optimized to accommodate the lower voltage output levels of OEM audio devices, making it particularly versatile in use. With appropriate sensitivity control, distortion and power losses are minimal, enhancing the enjoyment of precise bass representations.

How is the diaphragm of the Dieci DBA 201 F protected?

The diaphragm protection of the Dieci DBA 201 F is primarily achieved through a fixed subsonic filter set at 15 Hz and 24 dB/octave. This high-precision filtering protects the driver diaphragm from overexertion and effectively reduces the risk of over-excursion, which could lead to mechanical damage. Additionally, the massive ferrite magnet combined with the robust construction of pressed paper provides crucial support to minimize physical stress during intense bass. The durable Subwoofer is thus ready for the challenges of modern and bass-intensive audio productions.

What are the dimensions of the Dieci DBA 201 F and where does it fit in the car?

The dimensions of the Dieci DBA 201 F, with a width of 345 mm, a depth of 245 mm, and a height of 79 mm, allow for discreet installation of the Subwoofer in a variety of vehicle types. Its super-slim design is excellent for space-restricted areas, such as under seats or in tight corners of the trunk. By carefully measuring the intended mounting space in your vehicle, you can ensure that the Subwoofer fits perfectly. The sealed construction ensures that, regardless of position, the sound performance is not compromised. Customization options provide compatibility with many vehicle settings.

What type of filter does the Dieci DBA 201 F offer for sound tuning?

The Dieci DBA 201 F features both a variable 24 dB/octave low-pass crossover filter and a subsonic filter also at 24 dB/octave with a long-term cutoff at 15 Hz. This means you can flexibly adjust the low-pass filtered signals in the range of 50 to 150 Hz to seamlessly complement your speaker system. These filters combine to create an advanced sound palette that ensures bass frequencies are reproduced clearly and without distortion. Both DJs and sound enthusiasts benefit from these features to achieve optimal sound quality. The highly controllable filter structure offers outstanding precision and flexibility for passionate audio lovers.

How does the phase switch work on the Dieci DBA 201 F Subwoofer?

The phase switch on the Dieci DBA 201 F allows for a toggle between 0 and 180 degrees, enabling you to align the phase of the Subwoofer with the other components of your audio system. In practice, this switch helps to avoid interference between the Subwoofer and the main speakers, which can lead to cancellations or overlaps. Especially in more complex vehicle installations with various speaker positions, this can make a significant difference in the clarity and strength of bass reproduction. Such a fine-tuning mechanism effectively optimizes the spatial distribution of low frequencies.
