The new 3500 'd' Series subwoofers have been redesigned to utilize more features and manufacturing techniques from the 95/9900 series. The new 'd' Series motors are made just like their bigger brothers, we buy our own USA made steel, plasma cut to machinable size, then CNC'd to 1/1000ths of an inch accuracy. We have the parts plated for corrosion protection at a local shop and we then paint all inner motor suraces flat black to aid in heat transfer. The "d" series changes also include larger magnets (the magnet weight jumps to 170 ounces).

The 35s feature one of the largest voice coils in this market class - 3 inches in diameter. This large diameter voice coil helps produce the tremendous amount of force needed for todayís audio systems. This motor system also utilizes the DD exclusive FREE FLOW COOLING SYSTEM, now using the larger machined vents used on the 95/99 series. Separate 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 its only on DD products.

The 3500d also use 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 3500 'd' Series drivers capable of over 3.0 inches of useable, continuous excursion. The 3500d 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 3500d Series drivers 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 itís the best way we can.
