Kaladex-domed tweeters with a stout neodymium magnet.

Curvilinear gray woofer cones with Santoprene surround.

Give factory sound a serious power injection with a KS-Series Coaxial Speaker upgrade. With added improvements on the woofers and tweaked tweeters, dropping them in where factory speakers were seems like a no-brainer. The curvilinear, gray woofer cones, Santoprene surround, and newly designed basket give KS Coaxials the extra brawn to deliver a smooth, rich sound at any volume.

The half- and three-quarter-inch, Kaladex-domed tweeters contain a stout neodymium magnet dipped in ferrofluid for maximum coolness, recreating highs that rival live performance.

KS Coaxes are available in 10 sizes, from the capable 3.5-inch up to the marine-ready 6 x 9. The line includes a 6 x 8 for special applications. If you're looking for more from your doors, there's also a KS6930 3-way system in the lineup with an additional one-inch midrange.
