The ESB 1.6K2 is a two-way component speaker system from the 1000 Series, designed to bring a balanced and clear audio experience to your vehicle. This set features 165 mm woofers with pressed paper cones and rubber surrounds, which provide a sturdy foundation for the sound, while the 25 mm silk dome tweeters utilize neodymium magnets to ensure crisp high frequencies. With a nominal power of 70 W and a peak of 140 W, these 4 Ohm speakers deliver a frequency response ranging from 60 to 22,000 Hz. Installation is straightforward thanks to a modest mounting depth of 60 mm for the woofers, making them compatible with various car door panels. The system includes high-pass filters with a 6 dB/octave slope to protect the tweeters and refine the audio crossover. Because of their 90 dB sensitivity and ferrite magnets in the woofers, you can achieve a full, detailed sound without needing an overly powerful amplifier, making this kit an inviting choice for anyone looking to upgrade their factory audio with reliable components.
