More about the product
The Hertz CX100 Cento 4-Inch Coaxial Speakers are designed to provide clear and balanced sound in compact spaces. This model combines a 4-inch woofer with a coaxially mounted tweeter, delivering a full-range audio experience from a single speaker unit. It is ideal for vehicles where space is limited but sound quality is still important.
The woofer features a semi-pressed paper cone reinforced with mica. This combination offers natural sound reproduction with added stiffness for improved clarity and reduced distortion. The tweeter uses a Tetolon dome, chosen for its ability to produce crisp, detailed high frequencies without harshness, making vocals and instruments sound more lifelike.
The CX100 handles up to 40 watts RMS and 120 watts peak power, making it suitable for factory replacement or integration into a modest aftermarket system. Its 4-ohm impedance ensures compatibility with most car audio setups. The design focuses on efficiency and clarity, delivering strong output even when powered by a standard head unit.
Installation is simple thanks to the compact 4-inch size and included grille. The speakers are designed to fit easily into factory locations, reducing the need for modifications. The build quality reflects Hertz’s commitment to reliability, with materials chosen to withstand the demands of automotive environments.
While the CX100 offers excellent clarity and balance for its size, it is not intended for deep bass reproduction. Pairing these speakers with a dedicated subwoofer is recommended for those seeking full low-frequency impact. For users who value clear mids and highs in a compact form factor, the CX100 delivers impressive performance at an affordable price.

Look out for Bankstown Sound Recommendations
The Hertz CX100 is ideal for upgrading factory speakers in small vehicles or tight spaces. It offers better clarity and detail than basic OEM units, thanks to its coaxial design and quality materials. While it handles mids and highs well, it lacks deep bass, so pairing with a subwoofer is recommended for a full-range system. Compared to larger speakers, it is more compact and easier to install, making it a practical choice for simple upgrades without major modifications.
