The ESB HR 5C is a pair of 2-way coaxial automotive speakers from the Harmony series, designed to provide a balanced audio upgrade for your vehicle. Each 130 mm speaker features a pressed paper woofer cone with a rubber surround, which helps maintain durability and consistent sound reproduction. To handle the higher frequencies, a Mylar dome tweeter is integrated into the center, utilizing a neodymium magnet for precise performance. These speakers operate at a nominal impedance of 4 Ohm and handle 50 Watt RMS, with the ability to reach a peak of 100 Watt. They cover a frequency range from 70 Hz to 18 KHz with a sensitivity of 88 dB, ensuring they can be driven effectively by most standard car head units. The build is supported by a 9.1 oz ferrite magnet in the woofer and a 25 mm voice coil, making them a reliable choice for drivers looking to refresh their factory sound system with a dependable, compact solution.
