Titanic MKIII Subwoofers!
The best just
got better! We took our popular Titanic MKII Subwoofers and
made them even better! Our main goal was to create subwoofers
that produce deep clean bass, have high power handling
capabilities and long term reliability. The new Titanic MKIII
Subwoofers exceeded all of our expectations. These drivers
will work well in both vented and sealed enclosures, and with
their unique VCSTM cooling system, copper shorting ring, and
2-1/2" diameter voice coils, they can handle even more power
to produce higher output levels with less distortion! We've
used the finest materials available to ensure that each driver
is built to the highest quality standards for long-term
trouble-free performance even under extreme sound pressure
levels!
A. Rigid Cast
Frame
The cast aluminum basket features aerodynamic
supports that provide maximum rigidity for the motor structure
without impeding air movement from the rear of the cone or
causing unwanted reflections. The mounting flange features a
thick rubber gasket that not only provides an air tight seal
but also looks cool!
B. Ultra Stiff Composite Fiber
Cone
The cone is manufactured using the finest grade
pulp reinforced with Kevlar fibers and sealed with a
polymerized coating. The result is a very stiff cone that
remains stable even under the stress of very high sound
pressure levels.
C. Butyl Rubber Surround
A
large roll surround is used so the suspension has the travel
to handle the long excursions that this driver is capable of
producing. The surround is made of durable Butyl rubber for
long-term stability and reliability. The thickness of the
surround was precisely calculated to eliminate the possibility
of "suck back" in small enclosures, while still providing good
linearity.
D. Ventus Cooling System
(VCS)
This unique cooling system utilizes a vented
spider and pole piece. As the cone moves in and out, air is
drawn across the voice coil and through the motor structure
greatly improving its thermal capacity thus reducing
distortion and power compression. The harder you push the
driver, the greater the cooling effect!
E. Copper
Shorting Ring
A copper ring has been added to the pole
piece to counter the effects of back EMF (electromotive
force), resulting in reduced second harmonic distortion. By
locating the shorting ring at the top of the pole piece, we
also get the added benefit of reducing the effective voice
coil inductance.
F. Optimized Motor
System
The motor system features double stacked magnets
and an extended pole piece. It was optimized using FEA (Finite
Element Analysis) to ensure a strong symmetric magnetic field
in the air gap. The double-stacked magnets ensure there is
plenty of clearance to prevent the long-excursion voice coil
from bottoming. The motor system also features a long 2-1/2"
voice coil, which is wound on a Kapton former for improved
heat dissipation and higher power handling.
G. Flat
Progressive Nomex Spider
This proprietary spider is
made from high tech Nomex blended material for long term
stability. It provides a uniform restoring force throughout
its normal range of travel. As the driver nears its maximum
excursion the spider gets "progressively" stiffer. This
prevents the voice coil from accelerating out of the magnetic
gap during high output peaks reducing distortion and possible
voice coil bottoming. This unique spider also has the heavy
gauge voice coil leads stitched or "snaked" through the
spider. This eliminates "lead slapping" during extreme
excursion.
