Kenwood Excelon speakers incorporate technical know-how and advanced materials to give your music the full, rich sound it deserves. These full-range speakers sport a diamond-array pattern etched into their woofers that increases the strength of the carbon-polypropylene cone for improved dynamic response and lower distortion. The butyl rubber surround resists weathering, providing reliable support that keeps your music playing, no matter what. The KFC-X173 6-3/4" full-range speakers feature 3/4" silk dome tweeters that deliver all the high-frequency details without sounding harsh. Because of their specially designed magnetic circuitry and neodymium magnets, these compact tweeters use less steel in their construction than most tweeters, so you'll hear more accurate response.
