MB Quart DK2-116S - 6.5" Discus 2-Way Shallow Coaxial Speakers With Aluminum Inverted Dome Tweeters And Butyl Rubber Surrounds - 240 Watts Peak

Features & Benefits
Compatible Vehicle Fitment: Universal

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 magnet 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.
