THE ALIGNED DYNAMIC DESIGN:
The Model 1C 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 baffles
were each developed with the aid of FFT (Fast Fourier Transform)
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 One due to its
many potential advantages:
More precise 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.
Increased efficiency and improved dynamic range.
A stable impedance, assuring complete compatibility with any
amplifier or receiver.
THE COMPONENTS:
The active components used in the Vandersteen Model 1C combine
classic strength and durability with innovative design and construction.
The woofer uses the same type of cast-metal basket used in costly
esoteric loudspeakers. The cast-metal basket's inherent rigidity
and superior vibration resistance increase cone movement accuracy
and reduce sympathetic resonances for cleaner and more natural
sound. A filled polycone is used to insure high stiffness, superior
internal dampening and greater neutrality than metal alloy, woven
plastic or treated paper cones. The stiff, low weight polycone
resists flexing under all drive conditions for lower distortion
and increased detail. The Model One's transmission-line port extends
bass response while operating much closer to the ideal than any
of the more conventional ported or passive designs.
The metal 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 specific alloy
used for the dome was chosen for its superior strength and resistance
to break-up compared to common fabric and plastic domes. The quality
materials and advanced features of the Model One's tweeter result
in smooth and accurate response throughout the audible range.
The crossover of the vandersteen Model One is a transient-perfect,
first-order network designed to preserve the phase integrity of
the original sound. It is compensated to allow the drivers to
operate in absolute phase with each other while maintaining flat
amplitude response. This gives the Model One more precise imaging
and a more stable soundstage than conventional two-way speakers
using out-of-phase drivers. The crossover's computer grade components,
including film capacitors in the signal path, are hand soldered
on a double-sided, plated-through PC board for enhanced consistency
and reliability.
The baffles holding the drivers on the Vandersteen Model 1C are
as small as possible to eliminate virtually all of the early reflections
that affect dynamic speakers with conventional flat or low diffraction
baffles. Reducing both early reflections and edge diffraction
improves imaging and enhances the openness and transparency of
the speaker. The enclosure of the Model One is constructed of
MDF, a pressure-formed material that effectively resists vibration
and controls cabinet resonances. Broad spectrum, low-Q resonances
are controlled so as to cancel rather than become additive.
To insure consistency, each speaker is FFT analyzed for correct
response and performance compared to a model reference prior to
leaving the factory. The Model One combines superior components,
innovative engineering and quality construction for exemplary
performance and unparalleled value.
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 reveal the power,
the authority, the subtlety and the intimacy of the music.
This dimensional purity is the essence of the Vandersteen Model
1C. 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 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.
