TRUE TO SCIENCE AND MUSIC:
Since 1977, Vandersteen Audio has designed and built innovative
loudspeakers using advanced concepts such as minimum-area baffles
for driver mountings that virtually eliminate cabinet edge and
grille diffraction anomalies and mass alignment of driver elements
to insure proper time arrival. Vandersteen Audio was the first
loudspeaker manufacturer to use the Gen-Rad 2512 FFT (Fast Fourier
Transform) Computer Analyzer originally developed for the aerospace
industry, for in-house research and development and remains a
leader in interfacing complex computerized analysis of loudspeaker
parameters and performance with practical design and engineering.
The Model 2CE Signature II benefits from our years of experience
designing and building loudspeakers of unparalleled value and
performance. It couples proven technology with advanced materials,
construction and design for a speaker system that is always true
to both science and music.
THE ACTIVE COMPONENTS:
The components used in the Model Two CE Signature II combine classic
strength and durability with innovative design and construction.
The alloy dome tweeter is a dual-chamber design to improve range
and linearity. It is critically damped to extend the high frequencies
past audibility without the excessive ringing associated with
open or underdamped metal dome tweeters. The alloy used for the
dome was chosen for its superior strength and resistance to break-up.
The midrange and woofer use costly cast-metal baskets rather
than the more common stamped baskets. The cast-metal baskets'
inherent rigidity and superior vibration control increase cone
movement accuracy and reduce sympathetic resonances for cleaner
and more natural sound. Both drivers use filled polycones to insure
high stiffness, superior internal dampening and greater neutrality
than metal alloy, woven plastic or treated paper cones. The stiff,
low weight polycones resist flexing under all drive conditions
for lower distortion and increased detail. The midrange driver
features special construction and advanced acoustical techniques
to significantly reduce internal diffraction.
The active acoustic coupler accurately complements the woofer
to reduce box loss, thermodynamic loss and active/passive transfer
nonlinearities. This novel Electro-Mechanically Optimized Woofer
System provides powerful, detailed and extended bass response
as the Model Two operates much more closely to the ideal than
any conventional ported or passive designs.
THE CROSSOVER:
The crossover in the Model 2CE Signature II is comprised of transient-perfect,
first-order networks designed to preserve the phase integrity
of the music. Phase and impedance compensation allow the drivers
to operate in absolute phase with each other for more precise
and stable imaging than in conventional multi-way speakers using
out-of-phase drivers. The crossover's computer-grade components,
including low impedance air-core inductors and high-quality film
capacitors in the signal path, are hand soldered on a double-sided,
plated-through PC board for enhanced consistency and reliability.
Each completed crossover is tested to insure less than 0.1dB deviation
from a reference circuit. Like all Vandersteen Signature Products,
each crossover is hand tweaked with the speaker in an anacoic
chamber into matched pairs. Custom 6N wire with polypropylene
dielectric is used for internal wiring to maximize signal transfer.
The crossover is engineered for bi-wiring with a stereo amplifier
or passive vertical bi-amplification with two identical stereo
amplifiers. Inputs are barrier strips for optimum gas tight interface
(spade lug maximum width 7/16 inch # 10 screw).
THE CONSTRUCTION:
The baffles holding the drivers on the Model 2CE Signature II
are as small as possible to eliminate virtually all of the early
reflections that affect dynamic speakers with conventional baffles.
The edges of the baffles are curved to reduce diffraction. These
low-diffraction, minimum baffles improve the imaging and enhance
the openness and transparency of the speaker as baffle induced
interference is reduced.
With conventional speaker enclosures, the transmission of resonances
from the drivers causes secondary vibrations in the enclosure
that negatively affect the quality of reproduction. These enclosure
vibrations compromise the frequency response, imaging and resolution
of the speaker.
The Model Two's enclosure is constructed entirely of MDF, a pressure-formed
material that effectively resists vibration and controls cabinet
resonances. An accelerometer interfaced with an FFT computer was
used to determine the size, shape and thickness of each enclosure
part and the placement of the extensive internal bracing. Broad-spectrum,
low-Q resonances are controlled so as to cancel rather than become
additive. Enclosure vibrations and resonances are prevented from
interfering with the music.
To be compatible with your decor, hand-matched, natural oiled
wood veneers are used exclusively. An acoustically transparent
grille structure envelops the internal components of the Model
2CE Signature II.
THE ALIGNED DYNAMIC DESIGN:
The Model Two CE Signature II uses the proven Vandersteen Aligned
Dynamic Design to optimize the dispersion and transient accuracy
of the drivers while maintaining the input signal's time and phase
integrity. The drivers, their positioning and their associated
minimum-area baffles were developed with the aid of FFT computer
analysis to minimize diffraction, cone break-up, multi-driver
interference and out-of-band phase irregularities. The construction,
alignment and positioning of the drivers allow a point-source
wave front and maximize the phase coherence of the loudspeaker
at the listening position.
The Aligned Dynamic Design is used for the Model Two CE Signature
II due to its many potential advantages:
Precise, more dimensional imaging and a wider listening area.
A greater flexibility of placement options within the listening
room and better transient response.
A high level of genuine transparency and detail typical of planar
speakers without the distortions and response variations of multi-directional
dynamic loudspeakers.
A stable impedance, assuring complete compatibility with any
amplifier or receiver.
Increased efficiency and improved dynamic range.
QUALITY CONTROL:
Each Vandersteen Audio Model 2CE Signature II undergoes rigorous
testing and retesting during each phase of construction. Each
driver and crossover is tested for proper operation and computer
matched to within 0.1dB. After final assembly, each pair is high-power
sweep tested for structural integrity and FFT computer analyzed
for correct response and performance compared to a model reference.
This intense commitment to product quality and reliability is
unsurpassed in the audio industry.
DIMENSIONAL PURITY:
Music is pure in its dimensions. Vandersteen loudspeakers are
true to the original dimensions of the music. They preserve its
carefully crafted proportions and weight. They accurately convey
the composition, shading and timing that build an involving experience.
They reveal the power, the authority, the subtlety and the intimacy
of the music.
This dimensional purity is the essence of the Model Twos. It
allows them to recreate the music's original scope and passion.
You hear deeper into the music and better understand the feelings
forming its foundation. You become more involved in the music
as its complex inner structure is revealed with increased clarity
and realism.
At Vandersteen Audio, we believe that these qualities are fundamental
to your enjoyment of your music. We are pleased to have embodied
these qualities in a speaker whose simple, but elegant, physical
presence complements the decor of your listening room. We are
devoted to continue building distinguished loudspeakers that make
a statement about the importance of music in your life.
