The ESB HR 6C is a pair of 2-way coaxial automotive speakers from the Harmony series, designed to bring balanced audio to your vehicle. Each 165 mm driver features a pressed paper cone woofer with a rubber surround and a 13 mm Mylar dome tweeter, combining a 9.1 oz ferrite magnet for the low end with a neodymium magnet for the high frequencies. These speakers handle 50 Watts RMS and can reach peaks of 100 Watts, operating at a nominal impedance of 4 Ohm. With a frequency response ranging from 65 Hz to 18 KHz and a sensitivity of 88 dB, they provide a clear soundstage. The 25 mm woofer voice coil and 13 mm tweeter voice coil ensure reliable performance for drivers looking to replace factory speakers with a more capable audio setup.
