From the manufacturer
Cone: Poly Injection
Polyurethane 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 time.
Surround: Rubber
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. 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 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 Rubber Surround in our speakers can take the equivalent amount of abuse without quitting on you.
Basket: Stamped
Here are a couple of advantages of die-casting over stamping speaker frames. One of the more noticeable differences is the fact that a die-cast frame has better Resonant Frequencies. This means that the frame is able to absorb and transfer much of the energy produced by the speaker. It doesn’t vibrate like a bell would when it is stricken. Another advantage is that a die-cast frame is more durable and harder to damage or break.
Voice Coil: Aluminum
One of the most abundant elements on earth, Aluminum is remarkable for its low density and for its ability to resist corrosion. It is nonmagnetic (does not have any magnetic properties) and does not easily ignite. This solid material has the ability to perform under stress in both high tension and high compression environments. Aluminum is relatively soft making one of the more ideal materials to use in voice coils.
