The fully redesigned subwoofers from the Redline 200 series feature improved frames and suspension geometry, allowing for a lower Fs value and greater excursion, providing more depth in bass.

The redesigned voice coils have greater heat resistance and reduced inductance, offering a more balanced sound reproduction and increased power handling.

The red stripe at the cone junction and the thermally molded multi-layer suspension replace the red double stitching. The dust cap logo is made from reflective metallic foil.

All cones and dust caps feature a matte black finish, while the frames have DD logos either stamped or cast.

The triple venting of the voice coil and the braided wires in double, laminated, and extended pole pieces contribute to the exceptional performance of DD subwoofers.

The cone is made from a blend of fiberglass and paper fibers, coated with a moisture-resistant layer, providing a lightweight and strong cone that withstands automotive conditions.
