Fully Marinized + UV Protection + Water Resistant

But not water proof. There is a difference between the two.

Since the MRWT40 lives near the water most the time, all of the major components such as the spider, surround etc. have been specially coated and sealed exclusively for the protection that is needed from the corrosion present in a humid and salty environment.

The outside shell also has an Ultra-Violet coating to protect it from the damaging effects that the sun has to offer by maintaining material integrity and keeping them looking new.

Cone – Poly Injection

A substance called 'Polyurethane' and is categorized as a 'Polymer'. It is a resilient, flexible and durable manufactured material that can take the place of paint, cotton, rubber, metal or wood in thousands of applications across virtually all fields. It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue.

In the specific case of our cones, this material allows for maximum flexibility that produces great sounding speakers lasting you a long, long time.

Surround – Butyl Rubber

Butyl Rubber is a synthetic (man made) rubber and is valued for its chemical inertness, impermeability to air and the ability to endure or resist exposure to the many types of weather fronts. Butyl rubber has many different applications. Anywhere from Sports equipment to automotive parts, the medical industry and more. We use them for the Surrounds that connect the cone to the basket.

Did you know that most modern chewing gum uses food-grade butyl rubber as the central gum base, which contributes not only the gum's elasticity but an obstinate, sticky quality?

Just like that chewing gum, the Butyl Rubber Surround in our speakers can take the equivalent amount of abuse without quitting on you.

Midrange & Tweeter – Mylar

For a modern edge, the best car speaker could be the high tech Mylar tweeter, as it generally has more ability for a wider variance of sound modifications and channel handling. Unlike paper cones, the Mylar has a higher rate of durability, as the cone is made of a plastic poly material, which does not rip or tare easily, under abnormal frequency changes.
