Krome Audio Loudspeakers are designed to produce the extreme output that is necessary in the vehicles with multiple subwoofers. Clear and accurate sound reproduction will not only allow you to be the loudest, but will also allow you to enjoy the music. The impregnated cloth fiber surrounds, cast aluminum baskets, long strand Kevlar re-inforced paper pulp cones, and larger than standard voice coils are what make Krome Audio Loudspeakers dominate. GET LOUDER with less speakers!
