The Kenwood KFC-S1677EX is a pair of 6-inch (16cm) 2-way car speakers rated at 330W peak and 60W RMS per speaker, with a 4-ohm impedance and 87dB sensitivity. The woofer uses a cloth surround and ferrite magnet in a steel basket. The tweeter is a 25mm PEI balanced dome with a copper finish. Grille holders, tapping screws, speed nuts, and speaker cords included. 12-month warranty.
The KFC-S1677EX is a 6-inch 2-way speaker set suited to factory 6-inch and 6.5-inch speaker locations. The 123.6mm cutout diameter and 49mm mounting depth suit factory door and rear deck speaker cavities. The 25mm PEI copper balanced dome tweeter extends high-frequency response to 22kHz. At 60W RMS per speaker the KFC-S1677EX suits both factory head unit output levels and aftermarket amplifier setups. The 220g ferrite magnet is heavier than entry-level equivalents, contributing to stronger motor control across the woofer's operating range.
