View larger Midrange – Poly Injection Polyurethane categorized as a polymer 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 – Rubber Rubber is a synthetic man made material 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 applications from sports equipment to automotive parts the medical industry and more. 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. 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 it one of the more ideal materials to use in voice coils. 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. – Woofer: 4 inches – Tweeter: .79 inches – Peak power: 100 Watts – RMS power: 50Nominal impedance: 4 to 6 Ohms Frequency response: 100Hz – 20kHzSensitivity: 85 d – B 2.83v @ 1 Meter – Dimensions: 31.14 H x 2.09 W x 2.09 LWeight: 2.8 pounds Weather Proof Enclosed System 4 3-way Speaker Pair200 Watts MAX 100 Watts RMS Power Handling per Pair80 Hz to 18 k – Hz Frequency Response and 85d – B Sensitivity – Polypropylene Woofer Cone and Rubber Surround1 Tweeter and 1.5 inch Poly Cone Midrange Per Speaker
