The ESB 3.6C is a pair of 2-way coaxial speakers from the 3000 series, designed to bring a balanced audio experience to your vehicle. With a nominal diameter of 165 mm, these speakers handle a continuous power of 80 W and can reach peaks of 160 W, making them compatible with amplifiers ranging from 20 to 140 W RMS. They cover a frequency range from 65 Hz to 25 KHz, ensuring that both the low-end punch and high-frequency details are delivered clearly thanks to a sensitivity of 91.5 dB. Construction focuses on durability and acoustic precision, featuring a basket made of fiberglass-reinforced ABS. The woofer uses a pressed paper cone with a waterproof treatment to withstand humidity, paired with a high-damping single wave rubber surround for controlled movement. Inside, the 25 mm voice coil consists of an aluminum support with double-layer copper wire winding and an aluminum core, driven by a high-grade ferrite magnet. The integrated tweeter utilizes an N35 neodymium magnet to keep the high frequencies crisp and precise for anyone looking to upgrade their car's factory sound system.
