    Subwoofers for The Demanding Bassaholic with A Profound Interest in Physics

    9915.jpg

    These subwoofers were designed to provide long-term power handling, with accuracy, and high excursion capabilities. It’s been optimized for a 1500 – 2500 watt power band with the ability able to handle bursts of up to 10,000 watts. One look at the 9900 motor and you see why we call it the beast.

    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.

     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.

    Non-Pressed Paper Cones

    SFB

    These high-tech fibers have incredible strength and are further enhanced by using techniques to increase the cone cross section area without adding additional mass. The resin used creates a hard outer skin on the cone surfaces, creating a sandwich construction format. One skin cannot bend without the other skin doing the same, the further these skins are moved apart, the higher the resistance to mutual bending becomes. The ratio of increased strength is exponential, twice the thickness results in 4 times more rigidity. The newest DD synthetic blend cones are state of the art in cone technology and an integral reason why our speakers can supply high SPL and low distortion.

    DD Spiders

    The DD multi-spider suspensions start with layers of fine weave cloth impregnated with thermal activated resin.  These fine cloth sheets are then placed together with the weave grain at opposite angles, equalizing the inherent tension and increasing the strength. The layers are formed by heat and pressure until cured in molds with very high peaks and valleys. The two layers of fine cloth are far stronger than a single layer of heavier cloth, the higher surface area of the fine weave cloth gives more contact area for the resin. The high peaks and valleys, or corrugations, dramatically increase the strength over wide, shallow, progressive type rolls.

    Laminated Leads

    Another DD innovation was eliminating lead wire noise, breakage and suspension offset distortions with the introduction of our Laminated Lead Wire System. We pioneered this development as increased speaker excursion exceeded the limits that stretched tinsel jumping across the frame to cone gap could accommodate. The longer lead lengths cause excessive slapping against the cone as well as setting up oscillation modes that fatigued the wire.

    High-Temperature, Aluminum Former Voice Coils

    Aluminum Shorting Ring

    Free Flow

    This motor system also utilizes the DD exclusive FREE FLOW COOLING SYSTEM; separate cooling vents machined into the voice coil, top plate and pole piece which focus cooling air into the magnetic gap. This high-tech, precision machined cooling system actually lowers the working temperature of the voice coil, thereby lowering the stress on the entire audio system. The more the speaker moves, the more air is pumped onto the coil wire.

    Back Plate Coil Gap Venting

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

    DD Cast Baskets

    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. 

    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.
