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. View larger Midrange – Polyimide Cone Polyimides are a form of resin and family of some of the most heat and fire resistant polymers known. View larger 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. View larger Tweeter – Piezo Piezoelectric tweeters have several advantages over conventional tweeters.They are resistant to overloads that would normally destroy most high frequency drivers and they can be used without a crossover due to their electrical properties.The active element is basically a piece of polarized material (i.e. some parts of the molecule are positively charged, while other parts of the molecule are negatively charged). View larger Voice Coil – Aluminum Our speakers are capable of higher or elevated temperature strength and fatigue properties that will increase performance and efficiency of heavy duty play time through lower weight and higher operating temperatures.
