...ir). Speaker Impedance: 4 Ohms. Frequency Response: 55 Hz - 20 kHz. Sensitivity: 88 dB. Crossover Point: 2 kHz. Crossover Slope: 12 dB. Tweeter Dome Material: Aluminum dome tweeters deliver great sound with increased reliability.
Speaker Surround: Butyl rubber surrounds provide durability and deeper mid-bass impact. Voice Coil: Pure Copper voice coil creates a strong magnetic field with a very thin extrusion. Voice Coil Former: 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. Cone Material: Lightweight thermal-formed polypropylene cones enable faster midrange response.
Surround/Cone Coupling: The cone/surround connection utilizes a high temp 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. Tinsel Leads: Highly conductive while remaining flexible during high power applications. Cooling System: Over-coil cooling system allows air exchange over the voice coil through the spider.
External Component Crossover: External Passive Butterworth crossover for a smooth transition of frequencies f....
