Tweeters

Aluminum 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.

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 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.
