800 Series

Bass Cruiser

The 800 Series is aimed directly at the over the top bass cruising market. These subs get low and loud for an entire evening long cruise. The motor was designed around a humungorific 4 inch, high temperature, USA made, flat wire, aluminum voice coil.  This monster subs also possesses features such as backplate venting, basket venting and outer shorting ring/heat sinking to ensure the highest long-term heat dissipation possible.
The suspension is a combination of two DD Audio innovations. It utilizes a higher density EROM surround coupled with an exclusive multi-layer composite spider system. This style of suspension gives precise coil movement and long term durability under heavy use.
The new 800 Series is some serious equipment made for the system designer who is going all out in the pursuit of the ultimate bass experience.
800 Series Features:
  • Double Stitched EROM Surrounds 
  • High-temp 4.0”, aluminum former voice coil
  • Laminated Spiders
  • Non-pressed paper cones 
  • Cooling vent equipped cast aluminum baskets
  • Back plate coil gap venting
  • Extended pole piece

Direct Connect

We developed the most electrically efficient connections, the Direct Connect, one of the latest DD innovations now being copied the world over. First off, our multiple tinsel leads are twisted and soldered to copper power wire at the edge of the speaker frame. This twisted and soldered connection reduces any signal lost to an absolute minimum.

Our 10 gauge power cable is made from Oxygen-Free copper. Copper provides perfect contact in contrast to speaker terminals or push-down spring connections which are made from low grade metal. Many of these “pretty” (but poorly made) terminals have 0.1-0.2 Ohms of resistance in just the terminal housing. If you don’t believe us, unscrew one and watch it stick to the speaker magnet.

Another flaw of common speaker terminals is the inability to match up with large gauge speaker wire…And if one is able to find a terminal large enough to accept large gauge wire, it is still made from cheap metal thus the signal loss problem. Our 10 gauge power wire Direct Connects can be twisted (the best mechanical connection possible) with any gauge wire, AND also be connected with ANY number of wires. Series and parallel connections can be done in any combination and WITHOUT signal loss.

DD suggests the use of wire nuts for direct wire to wire terminations. Twisted wire connections are the only code approved termination in building codes due to the no loss transfer ability and permanently held connection. These same wire nut terminals are the perfect connection for mobile audio connections.

Direct Connect allows virtually any gauge and number of speaker wires to be connected without signal loss.

EROM

The surround uses our EROM( Extended Range Of Motion) profile, copied en masse to become an industry wide standard. The EROM design gives long, controlled excursion while keeping the cone diameter as large as possible. This profile also saves mass over the sculpted rubber surrounds and inner tube style surrounds, less mass is louder and faster.

The EROM profile, nearly parallel walls with a half-round top, is more self-supporting than the wide half-roll type surrounds. This enables the surround to become part of the suspension compliance, helping to control the high forces of the accelerating moving mass and enabling the coil to better track incoming signal.

The DD EROM profile innovation allows for more cone area, lower mass and increased stiffness. It’s no wonder than the DD EROM has become the most copied surround in the world.
