Rockford Fosgate M2 1" Marine Add-On Tweeter Kit 
The M2-TS 1" tweeter kit increases system overall sonic performance by adding to your existing M2 Color Optix full range speakers. The tweeter is protected with a stainless-steel mesh grille and can be installed using a flush or horn mount bezel. The Element Ready design and IPX6 certification makes them truly purpose-built for marine or motorsport applications where protection from damaging UV rays and water spray is essential. The M2-TS add-on tweeters do not incorporate built-in LEDs, but are designed to work with M2 Color Optix speakers that do.  Sold in pairs (2 each).
