These new DD Separates are an excellent way to upgrade sound quality at a price that will please any system budget. These DD Seperates consist of 28mm flush mounted tweeters, separate woofers and crossovers.

High quality parts are used throughout the drivers. The surrounds are formed from a high loss but light weight rubber to smooth the frequency response and keep the sensitivity as high as possible. The surround is attached to an injection molded, mineral filled polypropylene cone. This makes a rigid cone with good internal damping.

The voice coil uses the highest temperature wire wound on a reinforced, black anodized aluminum coil former. The machined motor structure helps keep the tolerances tight while providing the high energy magnetic strength needed for today's high output demands.

The tweeter is a 28mm, back vented neo magnet system with liquid cooling. The metal alloy diaphragm provides smooth response by moving breakup modes beyond the audible frequency range. The lightness of the diaphragm contributes to higher sensitivity and less strain at a given volume.

The crossover uses high power handling/low inductance parts, film capacitors and high voltage electrolytics. The laminated steel coils keep resistance low, cutting output losses to a minimum. A solid state fuse helps to keep the system safe when accidental overloads occur. The connections are gold plated to prevent corrosion. The tinsel leads run through the spiders to eliminate potential buzzing and improve durability.

The kits come with everything needed to mount in just about any situation, included are two crossovers, speaker wire, speaker grills and mounting tabs/screws.

The new DD Separates bring high-end performance within reach of any enthusiast, giving high value, ease of installation and high fidelity.
 

DD introduces a new line of coaxial speakers in 4", 5.25", 6.5", 5x7 and 6x9 sizes. These CX Series speakers have been designed to more compact dimensions than the DDC Seperates making installations possible in a wider range of vehicles.

These coax units are focused on smooth response found mainly in separate components. They share the same type of injection molded, mineral filled poly cones, rubber surrounds and 28mm vented back tweeter from our component line. The shallower profile reduces needed mounting depth while oversized voice coil diameters allow maximum heat dissapation. The coils use high temperature wire wound on black anodized aluminum formers reinforced with layers of insulating Nomex.

The tweeter is one of the largest available for coax units at 28mm. The large diameter makes high efficiency and high power handling possible without having to use harsher sounding cone type tweeters. It is more expensive to use 28mm, vented back neo magnet tweeters than common cone type units, but it is the best way to get increased output with smooth response.The tweeters are mounted at 15 degree offset to allow some shaping to the desired soundfield.

The CX line uses many high end design elements, tinsel leads are incorporated into the spiders, filtering is by high DF factor, 100Volt capacitors, secondary overcoat on all glue joints and rear vented tweeter housings. The CX line can bring separate component sound quality to the harder to fit applications.

These new DD midbass drivers offer unsurpassed installation flexibility and an excellent upgrade to sound quality at a price that will please any system budget.

The Z series represent the pinnacle of transducer archeology. The unique design dates back to the precocious era of unequivocal magnetism and the vector planar research of underwater acoustic proliferation. The open archeology concentrates flux lines in the magnetic gap while side lobbing interference cancels stray flux from entering the atmosphere. The result is increased efficiency over the entire bandwidth of collaborating bass frequencies. This allows the Z Series woofers to play amazingly loud with little wasted energy being dissipated as unwarranted heat, this means they get on it and don't get real hot.

The Z Series breaks new ground in rare earth magnetics, using newly discovered material, neo-demetrious iron proton (Ned), incalculably more strenuous than the other discovered rare earth magnet material. Ned is highly unstable and very difficult to modulate, yet alone saturate, so its use is mainly limited to noncommercial phase generators used in anti-matter plasma generation. Digital Designs has acquired the rights to use Ned magnetics in non-military acoustic weaponry and the peaceful development of humanistic cohesion through harmonizing wave generation. The unstable Ned blocks are held in symmetry by the side lobe interference which allows the use of the catchy monolithic block shapes from that cool 2001 space movie. These are spatially arrayed to over saturate the Permendur top plate imported from Switzerland in one of those really beautiful, lake filled mountian valleys, giving huge magnetic energy to drive the voice coils.

The moving parts of the Z Series have undergone a minute amount of scrutiny also, the cones feature newly contrived composite materials to handle the extra load lines emulating from the motor, the voice coils are spiral wound in reversing layer directions for optimum efficiency and the voice coil former is really strong. The combined technological oeuvre nearly eliminates all chance of spurious effluvium from occuring. The spiders also feature new technology never found on arachnid based suspensions, silkaleneotton. Genetically altered spiders produce a chemical blended thread of silk, polyethylene and cotton. This synthetic blend is superior to our other synthetic blend. The new synthetic blend is stronger than standard arachnid fiber, more flexible than polyunsaturated polyethylene, lighter than water (it actually floats) and yet so soft and comfortable. This material can stretch to 1.7 times its weight, allowing for un-presidential travel.

The new Z Series woofers have more Watts than any speakers we have ever built, so many Watts they got, that we thought of using a new slogan, Got Watts?, but that’s lame so we didn't. We tried to measure the exact amount of Watts a Z Series makes, but no matter how hard we tried to invent a machine to measure the speaker Watts, we could never do it, so they must really make lot of Watts.

We, at DD, strive to push the boundaries of a lot of things that are a big hassle to deal with. And why did we do all this... because we want to.

The 9500 'g' Series was designed with a singular goal in mind, to achieve the highest possible volume levels and to do so with the lowest possible distortion. The 9500 models are the most copied and cloned subs in today's car audio market, some even copy the name.

The new 'g' series design takes the 95's to even higher performance levels with a magnet system utilizing over 23 pounds of material and increasing the number of machined cooling vents.. These goals combine high efficiency, extended range of motion and high power handling in one package. 95's are engineered without compromise, and without a marketing department trying to capitalize on trendy fads. The long gap design keeps the highly efficient voice coils under power beyond 3 inches of throw. Voice coil control at extreme levels is crucial to clean output. The machined motor structure features the FREE FLOW COOLING SYSTEM which pumps cooling air through and around the voice coil with each and every stroke.

The SFB cone is a model of a high strength-to-weight ratio modern cone. These synthetic blend cones are strong enough not to flex at extreme power levels and light enough to react to quickly changing signals. The cone fibers like Kevlar, Polyester and Sisal allow less material to have higher strength than conventional cones and this low mass contributes to a fast transient response, which in turn lowers distortion. The suspension must also be engineered to many conflicting criteria to lower distortion at high excursion. The surround is the now often imitated EROM profile. This DD innovation allows long excursion while lowering mass and maximizing cone area. The spiders follow the same principal, reduce the surface area while increasing the corrugation heights. This results in long controlled motions while minimizing coil rocking and unwanted moving mass.

The 9500 'g' Series might be the ultimate woofer, hand assembled to the tightest tolerances in order to reproduce music as exact as possible, at whatever volume level you desire.

The 9100 series drivers are long magnetic field designs that have been optimized for high speed and low distortion. These drivers receive many of the improvements that R&D has developed on the 9500 and 9900 series drivers. The all new 9100s are true audiophile quality drivers that will excel in any application such as mobile audio, home theater, recording studios and esoteric high end audio.

Longer Magnetic Fields: The magnetic energy has been increased and a longer magnetic gap engineered to take advantage of that energy, over 60mm of linear field for the voice coil to travel in. A new 160 ounce magnet powers the motor that features our exclusive Free Flow Cooling System

New Spiders: A new spider topology was developed to increase the linear suspension travel and further reduce sources of distortion. This dual spider design is capable of increased throw with necessary control at high excursion.

New Double Lead Wires: The new double lead wire system is laminated into the spiders. This lowers the resistance added by the leads and provides redundancy for reliability.

New Cone Formula: A synthetic blend of fibers was developed with high rigidity as the goal while keeping the moving mass low. The synthetic fibers and resins we use make for a very rigid cone, which will not flex at high G-loads, and it passes along the signal as it was intended.

New Surround: The EROM surround replaces the previous half roll surround to increase excursion. The surround stiffness has been optimized with the spider suspension to add restoring force to the moving system while providing centering and stabilization under power.

New Voice Coil: The new dual 4 ohm coil was developed to reside in the long magnetic gap. Although this coil is lightweight and short in winding length, it is made with the highest temperature adhesives available. This combination yields low mass with excellent power handling.

The 3500 series is now optionally available with a Composite Cone!

The new 3500 'e' Series subwoofers have been redesigned to utilize more features and manufacturing techniques from the 9500 series. The "e" series changes include new cast baskets with more cooling and more excursion, larger magnets (the magnet weight jumps to 200 ounces), longer coil windings and increased internal motor cooling.

The 35s feature the same voice coils used in the 9500 Series - 3 inches in diameter with longer winding lengths than the previous Series. This large diameter voice coil and high energy motor combine to produce the tremendous amount of force needed to reproduce the impact in today’s bass intensive music. This motor system also utilizes the DD exclusive FREE FLOW COOLING SYSTEM, we increased the number of vents to spread the heat dissapation over a wider area. Seperate cooling vents machined into the voice coil, top plate and pole piece focus cooling air into the magnetic gap and around both sides of the voice coil with every up and down stroke. 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 harder the speaker works, the more air is blown onto the coil wire, cool, huh. Its one of our patent-pending designs and it's only on DD products.

The 3500e also uses our American made, Synthetic Spider Suspension, our Synthetic Fiber Blend (SFB) cone stock, and EROM surrounds. The lead wires are Direct Connection terminations with 10 gauge battery cable hook-up wire. These features combine to make the 3500e Series drivers capable of over 3.0 inches of useable, continuous excursion. The 3500e Series are all about extracting every last bit of efficiency from a system design.

In keeping with stringent DD standards, the 35s have low moving mass, use a well controlled suspension and are powered by our own precision machined motor assemblies. These features make the 3500e Series driver a perfect choice for a wide variety of system designs. The 3500 Series woofers have been part of award winning SQ systems, brutal ground-pounders, record setting SPL cars and countless enthusiast systems around the world. The DD way isn't the most cost effective way to build speakers, in fact its about 180 degrees off, but it produces the best speakers possible.

The 2500 'a' Series subwoofers were designed to extract the highest performance from today's power crazy car audio systems. High powered sound systems require high power subs that are built to handle the load. The 2500s match up well with the 500-800 Watt RMS amps driving a single woofer, or the 1000-1600 Watt RMS amps driving a pair. As is with DD's common design practice, the 25s share the same materials as the 35/95s, but with the 2500 motor designed for it's target excursion and power range.

Optimum performance requires a unique blend of design parameters/materials for these subs to hit hard, sound great and last a long time. The motor uses dual 25mm thick magnets sandwiched between 12mm thick, machined steel plates. Internal cooling vents from our Free Flow Cooling System keep fresh air circulating around the voice coil. The 2.5" voice coil diameter has sufficient surface area to handle the long term heat buildup while low enough in mass to keep high efficiency. The coil is coupled to our strong, multi-fiber cone that is reinforced with an epoxy based dustcap. The EROM surround is efficient in both excursion and minimal mass. The suspension follows our philosophy of multiple spider layers for tight bass with low fatigue over the long haul. The lead wires are laminated into these spider layers which further enhance durability and sound quality.

All our subs are hand assembled, rigorously tested and retested. We use multiple glue types and multiple glue joints for all attachment points. We use the most electrically efficient connections, direct copper to copper, the Direct Connect. Cosmetic options include real hand-laid Carbon Fiber dustcaps if so desired.

The 2500 Series subs are the perfect choice for systems stepping up in long term power requirements. The coils are designed using materials with the highest heat resistance on the market and are driven by a precision machined motor structure. The fatigue-resistant parts of the suspension use the finest USA made materials that can be found. These are subs designed to do a job and do it well, to fill your car with the kind of sound that makes you want to keep driving. We've spared no expense to deliver the goods.

The 1500 Series woofers are based on the 35/95 series design standards, bringing bass with power and authority to systems designed with 300-500 Watt RMS/per driver power levels.

The 1500 Series start with a powerful motor design using a 50mm thick magnet section, thick steel plates with 12mm thick magnet gap. The motor design is topped off with machined cooling vents from our Free Flow Cooling System pumping fresh air around the voice coil. The voice coil uses the same grade wire as our 9500 Series, the same high temperature capability and the same adhesives.

The surround uses our EROM profile to give 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 makes ours louder and faster. We developed new tri-laminated surround material which is highly elastic and very tough, perfect for daily rugged use. The cone is our multi-fiber blend designed for high strength and low weight, again, lighter is louder and faster.

The suspension in a subwoofer takes a real pounding, so the 1500 Series uses proven materials from the 35/9500 Series. The most durable spider materials are used in multi-spider arrangements in order to provide long but controlled excursion. We laminate our lead wires between spider layers to eliminate lead slap and broken lead wires. Our laminations cost more to produce, take longer to make, and take longer to assemble. They are built with USA made materials and tinsel lead, they are formed in the USA, cut, trimmed and laminated into spider assemblies in-house. Making longer lasting speakers doesn't happen by accident, it's a methodical and purposeful endeavor.

All our subs are hand assembled, rigorously tested and retested. We use multiple glue types and multiple glue joints for all attachment points. We use the most electrically efficient connections, direct copper to copper, the Direct Connect. Cosmetic options include real hand-laid Carbon Fiber dustcaps, if so desired.

The 1500 Series subs are the real deal; high quality subs at an affordable price that sound great while being as durable as possible. We think you should be able to enjoy your system for years to come, and then move your DDs to the next car you buy.

The new 510 and 512 woofers bring DD impact and durability to the most affordable price ranges we've ever offered. You still get the hand built, high performance quality at a price within every budget. The 500 Series was designed to optimize performance from amplifiers in the 100-300 watt RMS range. Not everyone is going to try to crush their tonsils with the latest bass jacked MP3, but that doesn't mean one should have to settle for lower quality parts or design.

The 500 series woofers benefit from the highest quality parts available, close production tolerances, and hand built quality as do all DD woofers. The motor and moving systems have been designed to get higher efficiency from lower powered systems. We found ways to reduce mass from the cone, surround, spiders and voice coil which raises the efficiency on a given level of power. The suspension stiffness and excursion capability were carefully dialed in through many real world test samples. The result is a very fast woofer capable of delivering surprising output from modest power sources.

The 500s feature multiple layers of durable cloth in the spider system, our exclusive laminated lead wires into the spider layers, double laminated half-roll surround, non-pressed cone and a motor system modeled after the 3500 Series woofers. The 510 and 512 are very easy to use in vented, sealed, and band-pass boxes and are the perfect presents in gift boxes. Now there aren't any excuses to get a DD system in every car.

The DDW6.5 mid-bass/mid-range driver was designed to deliver the widest possible bandwidth while providing a fast transient response with high levels of long term power handling. The cone is a composite blend of Kevlar fibre,carbon fibre and a very stiff and lightweight resin.

This combination has an excellent strength to weight ratio that is light enough to react quickly to complex signals yet rigid enough not to flex when subjected to extreme power levels. The surround is a well dampened rubber half roll. The motor structure incorporates long magnetic field technology which ensures precise control over cone excursions and efficiently dissipates heat from the voice coil.

The voice coil former is made from black anodized aluminum layered with arimid fiber and wound with the wire capable of enduring temperatures to 500 degrees F. The dual flat spider suspension is made from synthetic materials to give the smoothest response and long lasting durability.

The lead wires are laminated into the layers and run across opposite sides to even out weight over the moving system. The leads are terminated in 10ga. copper wire for the most efficient electrical transfer.

The DDW6.5 makes an excellent subwoofer in space limited systems and great for high powered midbass applications.
