The JVC CS-J520X car speakers feature a coaxial 13 cm (5.25 inch) design with a polypropylene cone woofer and a balanced 25 mm dome tweeter, allowing for clear audio reproduction in the frequency range of 60 Hz to 20,000 Hz. These 2-way speakers have a power handling capacity of 35 W RMS and 180 W peak power with a nominal impedance of 4 ohms, making them compatible with most standard car hi-fi systems. The compact 13 cm design is suitable for replacement in many vehicle door panels and rear shelves where factory-installed speakers of similar dimensions are used. Built with a durable butyl rubber surround and a stamped steel basket, these speakers are designed to withstand temperature fluctuations and vibrations typical of vehicle environments. The integrated crossover network ensures proper frequency distribution between the woofer and tweeter without the need for additional external components. With a sensitivity rating of 90 dB, these speakers deliver efficient sound pressure at moderate power inputs. The speakers come with grille protection and mounting hardware for easy installation, with professional installation recommended for optimal performance, as well as proper sealing and alignment. The CS-J520X model represents a reliable upgrade option for vehicles with factory audio systems, offering improved clarity and frequency response over basic factory speakers while maintaining the original mounting dimensions. These speakers are particularly suited for listeners seeking enhanced midrange and high-frequency details in their vehicle audio experience without requiring extensive modifications to their vehicle's audio system infrastructure.
