Kenwood KFC-S1066 4inch coaxial speakers

The Kenwood KFC-S1066 is a compact 10cm 2-way coaxial speaker for upgrading compatible factory car-audio locations. It combines a woofer with a balanced-dome tweeter to extend high-frequency response beyond a basic dual-cone design. Power handling is rated at up to 220W peak and 21W RMS, with a 4-ohm nominal impedance and 88dB sensitivity. The speaker covers approximately 50Hz to 22kHz and requires only about 43mm of mounting depth, making it well suited to smaller dashboard or door positions where installation space is restricted.
