CS-Series 6-1/2-inch Coaxial Speakers are the perfect way to upgrade your factory speakers. The stamped-steel framework supports a rigid polypropylene cone with EVC (Extended Voice Coil) technology for the best sonic quality. Using zero-protrusion PEI tweeters with neodymium magnets, you get the clarity you need without interfering with factory grilles. These CS speakers work best with 100 watts of continuous power.
