DD Audio DD-210-D4 200 Series DVC Subwoofer

The 200 series is designed to provide some satisfying boom on as little as 100-300 Watts. Enhancing these sub’s output efficiency is their smooth, wide bandwidth.

Note: Marine Grade products are not waterproof, and submersion or excessive moisture exposure may result in product failure. DD Audio Marine Grade products are not certified for saltwater environments.

REDLINE EROM Surround

EROM (Extended Range Of Motion) surrounds, pioneered by DD in the early 90’s, allow our subs to have higher, more linear excursion with more cone area than subs using wider surround profiles. Simply put, this surround design allows our subwoofers to make more and better bass than other subs out there. In fact, we like this surround style so much that some variation of it is used on all levels of our subwoofers. The REDLINE EROM surround features new signature aesthetics including a red accent line pressed into the surround and an embossed REDLINE logo.

REDLINE Voice Coil

REDLINE Spider

Spiders are the heart of a subwoofers suspension. Engineered to work with today’s music and system design trends, the multi-layer, multi-configuration REDLINE spiders achieve the perfect balance between control and compliance to deliver longer excursion and deeper bass.

REDLINE Cone

Utilizing a unique glass fiber and natural pulp formula, treated with a moisture resistant matte finish, REDLINE cones are ultra strong, yet impressively lightweight.

Back Plate Coil Gap Venting

The motor’s backplate features precision drilled vents in the coil gap for increased voice coil heat dissipation.

Extended Pole Piece

The REDLINE subs feature extended pole pieces for added high excursion control and improved heat dissipation.

DD Stamped Baskets

The DD stamped basket uses rigid steel with a specialized coating resulting in a sturdy, durable, low resonance design. It features precision punched DD logos incorporated into lower venting section.

10-Gauge Push Terminals

Push terminals allow for quick sturdy connections to the speaker wire coming from your amplifier. These terminals will accept up to 10-Guage speaker wire for delivering maximum power to the voice coil.
