|---|---|
| Tweeters | Aluminum inverted dome tweeters deliver great sound with increased reliability. |
| Cone Material | Lightweight thermal-formed polypropylene cones enable faster midrange response. |
| Surround / Cone Coupling | Butyl rubber surrounds provide durability and deeper mid-bass impact. 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. |
| 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 magnt 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. Tinsel Leads: Highly conductive while remaining flexible during high power applications. |
