SW9100 Titanium DVC Pro Series
SW9100 Titanium DVC Series
40
The SW9100 Titanium Double Voice Coil (DVC)
series subwoofers were developed to meet the
need for subwoofers that combine quick
response, efficiency and very high SPL
performance. These demanding specifications
required the development of the radical new
technologies used in engineering and building
the Titanium series subwoofers.
Performance that's a revelation
Apart from delivering prodigious amounts of
low frequencies, truly excellent subwoofers
show what they’re made of by the quality of the
low frequencies they produce. Along with
moving lots of air, the ability to define the pitch
of the low notes is important and to preserve
transients is crucial. To do that, subwoofer
cones have to be able accelerate fast. The ability
of the low-mass high X-max 15˝ to move faster
than a typical 8˝ woofer but provide bass like an
18˝ cone is what make the SW9100 Titanium
DVC Series deliver such exceptional
performance.
Solid titanium cone
The solid titanium cone adds the best of this
metal’s properties to the subwoofer: very high
tensile strength, high stiffness to mass ratio,
excellent heat dispersion and corrosion
resistance. At high power levels, the titanium
cone resists the cone flex that causes coloration
and distortion, moving air efficiently throughout
the full power handling range.
2-inch surround
The surrounds are two inches wide to
accommodate speaker travel of 3.5 inches peak
to peak excursion. Made of special polyether
foam that is resistant to ultraviolet radiation and
moisture, the surrounds have superior
mechanical properties and the low mass needed
to produce extremely high excursions.
Aluminum voice coil
The voice coil former is made of 8/1000˝ thick
aluminum, much thicker than industry standard,
to handle the stresses of the high power motor
at large displacements. The voice coil wire is a
high-temperature aluminum wire, used to
minimize mass and maximize thermal radiation.
Since the bond between cone and former is
thermally conductive, the voice coil heat is
quickly dissipated throughout the entire
titanium cone. The superior conductivity
combined with unparalleled heat dissipation of
this voice coil and former assembly means
more power transfer into the cone movement
instead of wasted heat.
Dual symmetrically arranged spiders
Two spiders designed with special non-linear
Finite Element Analysis (FEA) software are
spaced precisely apart to keep the voice coil
centered in the motor structure. The woven-in
tinsel lead wires are the ultimate in durability
and power transfer. The synthetic fabric used to
manufacture the spiders is four times stronger
than conventional material used in most
subwoofers.
High force motor structure
The motor structure was designed to maximize
the force versus displacement curve of high
excursion drivers. The motor has a unique
shape that results in 20% more force from the
same magnets than is normally achieved. The
magnetic field is very symmetrical above and
below the magnetic gap, contributing to a low
distortion and audibly superior driver.
QCA (Quick Change Assembly)
technology
ECLIPSE QCA exclusive technology has
designed the speaker to instantly allow
its two sections to separate in the event that the
speaker cone gets physically damaged. Simply
unlock the two sections with one allen key, twist
off the speaker assembly (QCA) and replace
with another.
Cast aluminum frame
The aluminum frame forms the skeleton of the
high performance Titanium series subwoofers.
Venting below the spiders accommodates the
enormous amounts of air that are moved during
operation, as well as keeping the motor
assembly free of any excess heat. The cast
frame also acts as a heatsink to dissipate any
additional heat produced from the subwoofers.
Triple-stacked magnet
ECLIPSE Titanium subwoofers feature a
extra-long magnet and pole piece to accurately
control woofer travel and enable high-power
performance.
One-piece machined back plate and
pole piece
The back plate and pole pieces of a Titanium
series subwoofer are machined from a single
block of low-carbon steel. This expensive
process yields a component part of unparalleled
precision and results in a highly efficient
magnetic circuit.
Aero-vented pole
The pole piece of the subwoofer is aero-vented
both outside and inside to facilitate the laminar
flow of air into and out of the voice coil area for
superior motor cooling. Aero-venting also
reduces vent noise in high driver travel
conditions.
The Advantage of
Dual Voice Coil (DVC)
Dual Voice Coil speakers are designed to
maximize space for more flexibility during
installation. A dual-voice coil speaker is
essentially two speakers in one: two separate
voice coils are connected to the amplifier.
Depending on the impedance of each voice coil,
the two can be combined in a parallel or series
configuration to match the impedance ability of
the amplifier. The dual voice coil design does
not sacrifice system power handling or SPLs.
