More about the product
The Hertz CBA250 Cento 10-Inch Active Subwoofer Box is designed to deliver deep, powerful bass in a compact and practical enclosure. This active subwoofer combines a high-performance 10-inch driver with an integrated amplifier, making it an all-in-one solution for upgrading low-frequency sound in a car audio system. The enclosure is carefully tuned to maximise output while maintaining clarity, ensuring that bass notes sound tight and controlled rather than muddy.
The CBA250 features a sturdy, sealed enclosure that reduces unwanted resonance and distortion. Its compact design allows for easy placement in most vehicles without taking up excessive space. The integrated Class D amplifier is optimised for efficiency and power, providing strong output while keeping heat and energy consumption under control. This design ensures reliable performance even during extended listening sessions.
The subwoofer is engineered to deliver a balanced sound that complements the rest of the audio system. It produces deep bass that adds impact to music without overpowering midrange and treble frequencies. The enclosure includes a protective grille to safeguard the driver from accidental damage, making it suitable for everyday use.
Connectivity is straightforward, with high-level and low-level inputs that allow integration with factory or aftermarket head units. Adjustable controls for gain, crossover frequency, and phase make it easy to fine-tune the sound to match personal preferences and system requirements. This flexibility ensures that the CBA250 can work well in a variety of setups.
While the CBA250 offers excellent bass performance in a compact form, it is not intended for extreme SPL or competition-level systems. Instead, it focuses on delivering clean, powerful low frequencies for everyday listening. Its combination of a quality driver, efficient amplifier, and well-designed enclosure makes it a practical choice for those seeking a noticeable improvement in bass without complex installation.
