Kenwood KFC-S1057 4 Inch Dual Cone Car Speakers 220W Peak 21W RMS 4 Ohm 88dB PP Cone Pair

The Kenwood KFC-S1057 is a pair of 4-inch (10cm) dual cone car speakers rated at 220W peak and 21W RMS per speaker, with a 4-ohm impedance and 88dB sensitivity. The woofer uses a polypropylene (PP) cone with cloth surround and ferrite magnet in a steel basket. No grille included. Tapping screws, speed nuts, and speaker cords included. 12-month warranty.

Product overview

The KFC-S1057 is a dual cone 4-inch speaker suited to factory 4-inch speaker locations in compact cars and vehicles where mounting space is limited. A dual cone design uses a secondary smaller cone attached to the main woofer cone to extend high-frequency reproduction without a separate tweeter, keeping the design simple and the overall mounting depth compact. The 102mm cutout diameter and 43mm mounting depth suit standard shallow factory 4-inch speaker cavities. At 21W RMS per speaker with 88dB sensitivity, the KFC-S1057 is suited to factory head unit power levels.

Note: no grille is included with the KFC-S1057. If a grille is required it will need to be sourced separately.

Frequently asked questions

What is the cutout diameter and mounting depth of the KFC-S1057? The KFC-S1057 requires a 102mm (4-inch) cutout diameter and has a mounting depth of 43mm. Confirm these dimensions suit your speaker location before purchasing.

What is a dual cone speaker? A dual cone speaker uses a secondary smaller cone attached to the main woofer to extend high-frequency reproduction, rather than using a separate tweeter. This keeps the design compact and straightforward while broadening the frequency range beyond what a single cone alone would reproduce.

What power handling does the KFC-S1057 require? The KFC-S1057 handles 21W RMS per speaker (220W peak). The 88dB sensitivity is compatible with standard factory head unit output levels.

Does the KFC-S1057 come with a grille? No. The KFC-S1057 does not include a grille. Tapping screws, speed nuts, and speaker cords are included. A grille must be sourced separately if required.

Are these compatible with factory head units? Yes. The 4-ohm impedance and 88dB sensitivity are compatible with standard factory head unit outputs without amplification.
