2-Way Component System: 6.5-inch (165 mm) Woofer, 0.75-inch (19 mm) Aluminum Dome Tweeter
C1 speakers deliver real substance and great audio performance in a format designed for easy fit behind factory grilles.
To facilitate fit, multi-application adaptor rings are included for the C1-650 woofers, allowing easy, drop-in installation in vehicles equipped with oversized 6.5-inch and 6.75-inch speaker openings. Without the ring, the woofers will also fit into many "6-inch" speaker locations as well. Surface and flush mounts are included with C1 tweeters for maximum installation versatility.
