Kicker 51KSS6504 KS Series 6.5" Component System With 1" Tweeters, 4ohm KICKER KS-Series Speakers let you play at concert-like volume, yet maintain the smoothness and subtlety to please even the most selective ear.

Experience your music as a component system with separate tweeters, or as a high-end coaxial system. The woofers’ removable bullet-style phase plug is replaced with a special adapter, allowing the 25 millimeter, silk-dome tweeters to rotate and tilt.
