Model Seven Mk II
The Vandersteen Flagship
We are very
proud to introduce the Model Seven Mk II, the newest Vandersteen
flagship! The chief improvement in the Model Seven Mk II was achieved by
mechanically altering the "acoustic lens" that surrounds midrange and
tweeter, aligning the acoustic centers of those drivers just enough to
substantially decrease the amount of hand tuning required for the
compensation network. The result is even more natural, open sound for a
soundstage that is palpably taller, wider and more "3D" in its image
focus and specificity. Additional improvements were realized by weaving
the voice-coil leads directly into the spiders of the push-pull
subwoofer cones in the powered subwoofer, strengthening the connection
between the Model Seven MK II's integral power amplifier and subwoofer,
allowing increased linear excursion for even greater bass authority in
the subterranean (100Hz and below)

2015 PRODUCT OF THE YEAR- THE AUDIO BEAT
"A genuine flagship
performer, regardless of size and price, the Vandersteen Model Seven Mk
II takes holistic design to another level." -Roy Gregory, The Audio Beat
Meet the Model Seven Mk II, the
newest Vandersteen Audio flagship! The original Model Seven was
introduced in 2009 and remained in constant production for over five
years, an unprece- dented run during which it was firmly ensconced as a
Stereophile Class A Recommendation, a perennial TAS Editor’s Choice
winner and a winner of universal praise from reviewers and consumers
around the world. All of which is testament to the fact that the Seven
was a tough speaker to improve upon!
However, Richard and Nathan Vandersteen, the architects of this
ambitious project found that mechanically altering the “acoustic lens”
that surrounds midrange and tweeter aligned the acoustic centers of
those drivers just enough to substantially decrease the amount of hand
tuning required for the compensation network. The result is even more
natural, open sound for a soundstage that is palpably taller, wider and
more “3D” in its image focus and specificity.
Although the crucial aspects of the Model Seven’s ultra-rigid
carbon-fiber “cabinet within a cabinet” construction remain familiar
with the Mk II, the tighter physical integration of the tweeter/
midrange interface creates a more elegant appearance with the grill
cloth on, and a look we are pleased to note also increases the visual
similarity between Vandersteen’s flagship speaker and the liquid-cooled
Further sonic improvement was realized by weaving the voice coil
leads directly into the spiders of the push-pull subwoofer cones in the
powered subwoofer, strengthening the connection between the Model Seven
MK II’s internal power amplifier and the powered sub, allowing increased
linear excursion for even greater bass authority in the subterranean
(100Hz and below) frequencies.
Of course the beating heart of the Model Seven Mk II is the patented carbon-fiber-clad Perfect-PistonTM
drivers that made the Model Seven a sensation. Richard Vandersteen
spent 10 years developing these amazing carbon cones, a completely
original technology which realizes the dream of true pistonic linearity
from dynamic driver cones without the unnatural sonic color- ations
inherent in metal driver cones.
The Model Seven Mk II employs Vandersteen’s most powerful and refined
powered-bass system. Each speaker incorporates a 400- watt amplifier
with a dual-motor, push-pull subwoofer comprised of two 12” curvilinear
aluminum cones sandwiched together and 11-band room EQ. A passive,
first-order (6dB/octave) high-pass filter allows the main amplifier to
perform its best, unburdened
of reproducing deep bass. Passive speaker designs always require
placement compromises between the areas in the room where the imaging is
best (farther out in the room) and where the bass is best (closer to
the walls for boundary reinforcement). The Model Seven Mk II can be
placed out in the room where it images best, while the 11-band EQ
ensures “unbeatable” in-room powered- bass performance.
The flagship Model Seven Mk II is entirely uncolored and free of
cone-imposed distortions that even the most astute listeners never
identified as originating from the loudspeaker itself. The Perfect
Pistons’ startling linearity opens an entirely new window on your music
collection revealing nuances only heard by the artists and artisans who
made the original recording.
The Model Seven Mk II's advances are rooted in their 30 year-old
cornerstone concept, which is to design full-range, time- and
phase-accurate, minimum baffle, vertical array speaker systems.
We introduced this concept with the original Vandersteen Model 2 in 1977
and the fact that narrow speakers with vertically-arrayed drivers are
ubiquitous today further demonstrates both the influence and validity of
this speaker design.
Everything they do at Vandersteen Audio revolves around one simple
precept… serve the source. In the case of loudspeakers this means
faithfully preserving the waveform produced by the power amplifier,
including all of the delicate time-domain relationships that comprise
the recorded musical performance.
They develop and blend both engineering and technology to act as
conduit between you the listener and heightened satisfaction from your
Perfect-Piston™ driver diaphragms. Vandersteen has
revolutionized loudspeaker design by combining structural engineering
and material technology to create diaphragms that act as perfect pistons
throughout their operating ranges and beyond. The unique diaphragm
material used to make Vandersteen Perfect Piston™ Drivers marries carbon
fiber and balsa wood in a unique 3-layer configuration with the highest
stiffness-to-weight ratio available and allows all direct-radiating
drivers to utilize diaphragms made from the same materials.
Fusion™ Subwoofers. The unique dual-motor, push-pull
subwoofers two curvilinear aluminum cones sandwiched together with an
exotic honeycomb material built-in to Vandersteen Model Seven Mk
II loudspeakers are unlike anything else on the market. They don’t
simply “augment” bass. They extend the low frequency response of the
speakers while reducing distortion in the midrange. Bass response and
harmonic response are fused together in a seamless blend, maintaining
full-range amplitude linearity and phase-response.
Stealth™ Enclosures. The structure or body of a
musical instrument, like a piano, violin or guitar, is designed to add
rich and pleasing resonances to the sound of the strings. Any sound
created by the structure of a loudspeaker is distortion so all
resonances should be eliminated. Vandersteen Stealth™ enclosures
eliminate these distortions by virtually eliminating resonances,
minimizing baffle dimensions and covering the remaining surfaces with
non-reflective materials, and carefully contouring all edges.
Vandersteen speaker enclosures are acoustically inert. All structural
panels are made from proprietary constrained-layer-damped materials and
heavily braced. Vandersteen Model Seven Mk II speakers have additional
carbon fiber layers applied inside and out with a
high-pressure, high-temperature autoclave.
cohesive by design…
Creating and integrating the finest components is a start, but not
good enough. Equally important is the abilty for those components to
perform as desgned in the presence of other elements – Vandersteen
loudspeakers have established the ability to perform with an organic
ease and pace, with natural timbre and tonality, without cmpromise.
The custom laser tool shown above is part of the dealer installation
kit used to precisely adjust speaker tilt and toe-in, along with bass
400-watt amplifier. In each Model Seven Mk II,
Vandersteen integrates an ultra-high-current 400-watt amplifier with
power-factor-corrected, regulated power supply. The Eleven-band bass
equalization, plus master level control, along with Adjustable“Q”™ allow
bass response to be perfectly tailored to a myriad of speaker positions
in a variety of rooms. Vandersteen’s phase coherent bass EQ is unique
because it affects low frequencies only; there is no processing in the
signal path above bass frequencies all within the analog domain.
