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 today’s 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
it’s the best way we can.
