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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eNote: no grille is included with the KFC-S1057.
