Frequently Asked Questions about CBA 250

What is the impedance of the Hertz CBA 250 Subwoofer?

The Hertz CBA 250 active Subwoofer has an impedance of 0.4 ohms. This low impedance contributes to the high efficiency of the Subwoofer and allows for more power to be extracted from the Amplifier. Combined with the specially adapted high-performance amplification module, which can deliver a nominal power of 250 watts RMS, it produces high-quality and powerful bass. This is particularly notable when reproducing low frequencies, ensuring dynamic audio playback.

What power can the amplification module of the Hertz CBA 250 Subwoofer deliver?

The amplification module of the Hertz CBA 250 active enclosure Subwoofer is designed to provide a continuous power output of 250 watts RMS. This is achieved through the use of He-Li technology (high efficiency / low impedance), which increases the module's efficiency to an impressive 90%. Additionally, the Subwoofer has a peak power capacity of 500 watts. This technical setup ensures that there are no quality losses even at high volume. Especially if you enjoy listening to music loudly, the sound remains clear and the bass powerful.

What frequency curve does the CBA 250 Subwoofer offer?

The Hertz CBA 250 Subwoofer offers an extensive frequency range coverage from 20 to 200 Hz. This allows for overwhelming reproduction of low frequencies, providing an impressive bass experience. The adjustability through the integrated Butterworth low-pass filter, which cuts off at 12 dB/octave and can be set variably between 50 and 200 Hz, allows you to optimally tune the sound to your individual preferences or bypass the filter for external processors.

What are the dimensions of the Hertz CBA 250 Subwoofer?

The external dimensions of the Hertz CBA 250 Subwoofer are 440 mm in length, 334 mm in width, and 135 mm in height, with a stand base bringing it to 158 mm. Thanks to this compact design, the Subwoofer can be easily integrated into many common vehicles without worrying about excessive space requirements. The ultra-compact construction offers maximum flexibility for installation in the vehicle, even in limited space.

What type of magnet is used in the CBA 250?

The Hertz CBA 250 Subwoofer uses a high-density ferrite magnet. Ferrite magnets are known for their strong magnetic force and provide reliable performance. Measuring 140 x 70 x 30 mm, these magnets work in conjunction with the 10-inch driver to deliver powerful and precise bass reproduction. The choice of a ferrite magnet supports the goal of producing rich and deep sounds that are clear and free of resonance at any volume.

How does the bass boost control work in the Hertz CBA 250?

The bass boost control of the Hertz CBA 250 allows for adjustment of the bass level in the range of 0 to 6 dB at 45 Hz. This control gives you the ability to specifically enhance the bass in the lower frequency ranges to customize your audio enjoyment. Such adjustments are particularly helpful in larger or acoustically challenging environments to highlight the bass and achieve a well-rounded sound. Fine-tuning can help tailor the sound perfectly to your listening preferences.

Which audio systems is the Hertz CBA 250 compatible with?

The Hertz CBA 250 is compatible with a variety of audio systems thanks to its high-level and low-level inputs. The high-level input on the multi-pin connector facilitates integration with existing OEM audio systems, while the low-level input on the RCA allows connection with external sound sources. This flexibility in integration makes the CBA 250 an ideal choice for various vehicle brands, which do not need to be specified, as universal compatibility is the priority.

What features does the 2S² design of the Hertz CBA 250 have?

The 2S² design of the Hertz CBA 250 stands for '2 sides / 2 sounds' and focuses on maximum efficiency and sound quality. It offers optimization of air and sound flow within the enclosure, resulting in outstanding, powerful sound. This design combines advanced acoustic technology and space-saving construction to ensure both punchy bass and flexibility in installation. Ideal for easy integration into almost any vehicle without compromising sound quality.

How does the Xmech of the Hertz CBA 250 affect the sound?

The Xmech or maximum mechanical displacement of the CBA 250 is 14.75 mm, which plays a significant role in bass reproduction. This specification indicates how far the diaphragm can be displaced from the center position before distortion occurs. A high value for the Xmech ensures that the cone can perform large displacements without damage or sound distortion, which is particularly crucial when reproducing dynamic, bass-heavy music passages. This significantly contributes to a clean and powerful sound.

What materials are used in the Hertz CBA 250?

The Hertz CBA 250 uses high-quality materials to ensure long-lasting and robust performance. The cone of the Subwoofer is made of pressed paper, known for its good sound quality while being lightweight. The voice coil diameter is 60 mm and is made of copper, which provides excellent thermal conductivity. This choice of materials is crucial for the durability and efficiency of the Subwoofer, as it helps minimize weight and maximize sound performance.
