MB Quart Formula Series 2-Way Coaxial Speakers (3.5")

WIDESHERE creates a large "sweet spot" for all listeners, even from the smallest speakers. Aluminum dome tweeters deliver high output, extended frequency response and natural music reproduction. Butyl rubber surrounds provide durability and deeper mid-bass impact. Textured ABS gasket assures a rigid linear seal to the mounting surface. Pure copper voice coil creates a strong magnetic field with a very thin extrusion. Kapton voice coil former is lightweight and efficiently dissipates heat. Natural fiber allows flexibility while the infused epoxy gives strength during the manufacturing process. Over-coil cooling system allows air exchange over the voice coil through the spider. Heavy gauge progressive-die stamped steel frames for ultimate rigidity.
