The Focal ICU690 is a 2-way coaxial speaker kit designed to bring a balanced and clear audio experience to your vehicle. These 6x9 inch speakers handle 80 W RMS and up to 160 W of maximum power, utilizing a 4 Ohm impedance and a sensitivity of 93.6 dB/W/m to ensure efficient performance. The sound is produced by a Polyglass® cellulose composite woofer and an inverted dome tweeter made from an aluminum-magnesium alloy, which together cover a frequency range from 55 to 21,000 Hz. To help you tailor the sound to your preference, the kit includes an integrated 6 dB/octave crossover and a high-frequency level adjustment that allows you to switch between flat and +3 dB settings. The physical design features a compact chassis with mounting dimensions of 147 x 218 mm and a depth of 83.5 mm, making installation straightforward in most compatible car doors or rear shelves. The tweeter is further enhanced by an acoustic horn design to improve sound projection, though you should note that these speakers are supplied without protective grilles.
