The completely renewed Redline 600 series subwoofers have many things that make them better than their predecessors. Redesigned frames and suspension geometry allow for a lower Fs value and a larger range of motion. These two things give you MORE LOW BASS. The renewed voice coils have greater heat resistance than before, reduced inductance and better efficiency. Thanks to these things, you get a more balanced reproduction, more sound with the same amplifier and more power endurance. The red double stitching that used to be characteristic of the DD Redline is no longer there, instead there is a red stripe or redline at the junction of the cone and the heat-molded multi-layer upper suspension. The logo of the dust cup is made of reflective metal foil. All cones and dust cups have a matte black finish. The frames have DD logos either die-cut or cast. Triple venting of the voice coil, wires braided into a triple underlay, laminated underlays and extended pole pieces that have always made DD subwoofers such functional entities can still be found in the new models. The cone is a mixture of fiberglass and paper fiber and coated with a moisture-resistant coating. This has resulted in a light and strong cone that withstands the conditions in the car very well.
