Best in Class
The 500 series is one of the best performing subs you can find in its power class. With a highly efficient design, the 500 series can easily be driven to high output levels on as little as 150-400 Watts. When compared to the 200 Series the 500 Series uses a longer coil, more powerful motor and the suspension is designed to handle higher transient peaks. These are very versatile subs that work well in sealed enclosures while providing the extra energy and control needed for vented enclosures applications.
500 Series Features:
- EROM surround
- High-temp, 2.0”, voice coil
- Double Layer Deep bass, high excursion spider system
- Unique glass fiber and natural pulp cone
- Back plate coil gap venting
- Extended pole piece
- DD stamped steel basket (508-512)
- DD cast basket (506)

Any DD Audio Product bearing the Marine Grade logo incorporates water resistant features enabling it to be used in applications where moderate exposure to moisture will not result in damage to the product.
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.
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.
These high-temp voice coils are wound with USA made wire and held together with USA made adhesives. They feature a thick-walled, black anodized aluminum coil former for superb heat transfer.
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.
Utilizing a unique glass fiber and natural pulp formula, treated with a moisture resistant matte finish, REDLINE cones are ultra strong, yet impressively lightweight.
The motor’s backplate features precision drilled vents in the coil gap for increased voice coil heat dissipation.
The REDLINE subs feature extended pole pieces for added high excursion control and improved heat dissipation.
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.
DD cast baskets are custom designed for strength, stability, and precision. Using cast aluminum allows for added heat dissipation properties as well as high rigidity and low resonance. All these qualities combined, result in a basket that supports powerful high excursion designs.
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.
