Amp up how you listen to your car's audio with a pair of the Hifonics Zeus ZS65CXS 6.5-Inch 3-Way 300-Watt Shallow Mount Coaxial Speakers. These shallow mount coaxial speakers have neo mylar soft dome tweeters built to resist impact, are reliable, and provide superior audio quality. The 1-inch tweeters are able to clear highs and handle high power without sounding harsh. Rubber surrounds also provide high mid-bass impact. Alpha cellulose poly woofer cones are extra lightweight and rigid for increased speed and deep base. Passive butterworth crossovers provide smooth transitions of frequencies and anti-resonant stamped steel basket frames keep harmonics to the minimum by preventing distortions from flexing or ringing. The mounting diameter is 5.59 inches with a mounting depth of 1.65 inches. This package also includes a pair of Hifonics Zeus 5.25-Inch 2-Way 200-Watt Coaxial Speakers that pack a punch. Made from neo mylar and alpha-cellulose that's nearly as strong as the Greek god himself, these speakers stand protected against moisture and impact. Additionally, the frame is made from anti-resonant stamped steel, which prevents distortions that could affect your sound. The mounting diameter is 4.48 inches with a mounting depth of 2 inches.
