The ESB 3.6K2 is a two-way component speaker system from the 3000 series, designed to bring a balanced and detailed audio experience to your vehicle. This set combines the ESB 3.165 mid-woofer with the ESB 3.28 tweeter, all managed by the ESB 3.6K2CX passive crossover to ensure a smooth transition between low and high frequencies. At the heart of the low end is a 165 mm mid-woofer featuring a pressed paper diaphragm with a waterproof treatment, which helps maintain performance even in humid conditions. Its basket is crafted from glass-filled ABS plastic for high torsional rigidity, supporting a Y-35 grade ferrite magnet that handles a nominal power of 120W and peaks at 240W. This component covers frequencies from 65 Hz up to 9 kHz with a sensitivity of 91.5 dB, providing a solid foundation for your music. High frequencies are handled by a 28 mm soft dome tweeter made from silk-impregnated fabric, which lends a natural tone to the sound. To keep the audio clear and controlled, the voice coil is ventilated and damped with iron-fluid oil. With a nominal power of 90W and a frequency range extending up to 25 kHz, these tweeters offer the precision needed for crisp vocals and instruments, making this system an inviting choice for anyone looking to upgrade their car's interior sound quality.
