Features
Polypropylene Woofer Cones: The Kicker KS-series speakers feature durable polypropylene woofer cones for power and control. Polypropylene is also resistant to the moisture and temperature extremes found in automotive applications.
Santoprene Surrounds: The woofer surrounds are made of Santoprene rubber to allow extended cone excursion for additional bass output and higher SPL. Santoprene is durable and resists moisture for a long life.
Balanced Dome Tweeters: The 1/2" PEN (Polyethylene Naphthalate) balanced dome tweeters provide a smooth high frequency response with a wide dispersion pattern. The tweeters have strong neodymium magnets for higher power handling.
Grilles: The KS40s come with a pair of graphite-colored, plastic, spoke-style speaker grilles.

For such a small speaker it does a good job providing a wide variety of sounds however it struggles slightly (as expected) when it comes to bass but in all I am satisfied with my purchase
