Hit the road with the big, rich, detailed sound the JBL® brand is famous for. In your car. Yes, your car. In addition to the serious bass of a Plus One® woofer cone, an edge-driven My-Ti™ super tweeter produces extended high frequencies like the best home audio speakers do. This is attention to detail rarely given to car audio. And it changes everything.
