TWEETERS 1" Aluminum dome tweeters deliver great sound with increased reliability. CONE MATERIAL Lightweight thermal-formed polypropylene cones enable faster midrange response. SURROUND/CONE COUPLING The cone/surround connection utilizes a high temperature adhesive, which assure the cone and surround do not separate in high power uses or extremes of weather. GASKET A textured ABS gasket assures a rigid linear seal to the mounting surface. ​VOICE COIL/FORMER ASSEMBLY Pure Copper voice coil creates a strong magnetic field with a very thin extrusion / Kapton voice coil former is lightweight and efficiently dissipates heat. SPIDER Natural fiber allows flexibility while the infused epoxy gives strength during the manufacturing process. COOLING SYSTEM Over-coil cooling system allows air exchange over the voice coil through the spider. CROSSOVER 6dB internal crossover integrated into the design to assure smooth midrange to tweeter frequency transitions. FRAME Heavy gauge progressive-die stamped steel frames for ultimate rigidity. MOTOR Ferrite maget motor creates a strong magnetic field while remaining small enough to fit nearly every application. CONNECTORS Use spade connectors or solder direct for the best connection.
