MB Quart DK2-116 Discus 6.5 inch 2-way coaxial car speakers pair aluminum inverted dome tweeters with lightweight thermal-formed polypropylene cones, so midrange stays quick and vocals come through clean. Butyl rubber surrounds and a high-temp adhesive bond hold the cone and surround together through high-power use and weather extremes, while the 6dB internal crossover keeps the transition from midrange to tweeter smooth.

Pure copper voice coils on Kapton formers build a strong magnetic field and shed heat efficiently, and the over-coil cooling system moves air across the coil through the spider. Heavy gauge progressive-die stamped steel frames keep everything rigid, ferrite magnets fit nearly any mounting location, and spade connectors or direct solder both work for hookup.
