Israel Blume has been at it again. For the past
few years he has brought a
new design to the market annually with the Grand
Victory his latest attempt
to conquer yet another segment of the high-end market.
Appearance:
Well, Grand is a good description of the Victory
loudspeakers as their size
is imposing, almost intimidating: 52 inches high,
11.5 inches wide and 22
inches deep. In addition, each enclosure weighs
a hefty 200 pounds. Even
though the cabinets are large, they boast an immaculate
finish on all sides.
The driver array on the front baffle contribute
even more to the cabinets'
stately look, as there are four woofers and a ribbon
tweeter to magnify the
overall impression. Grilles are optional. Four connecting
terminals allow
bi-wiring or biamping, though two amplifiers are
unnecessary as the GVs are
very efficient, which brings us to the systems.
Technology:
Four woofers and a tweeter is an unusual driver
configuration, and it is
just as uncommon to find that the bass drivers all
work in phase and in
parallel connection, crossing to the higher tweeter-generated
frequencies at
2.2kHz. This translates to a (not so simple) 2 way
design which employs a
more sensitive variation of the ribbon tweeter used
in the Victory and Total
Victory models complemented by four 8 inch woofers.
The woofer cones are
paper treated resulting in low mass but high rigidity
and operating in a
prodigious magnet assembly. The (cone) suspension
system is very rigid and
responds quickly to an incoming signal, providing
an ideal environment for
the piston-like excursion generated by small or
large amplifiers. Blume
tuned the GVs very tightly and they are highly damped
to complement
amplifiers with low damping factor, such as single
ended triodes. This is
likely the reason why, when paired with these speakers,
the Wyetech Labs
Sapphire monoblocks (reviewed in this issue) provided
exemplary tight bass.
The isodynamic ribbon tweeter used in this design
has the same sonic
characteristics as the unit used in the Victory
and Total Victory speakers,
but features a more powerful magnet assembly and
3db higher sensitivity. It
is finished off with a solid brushed aluminum face
plate to achieve rigidity
and diminish induced resonances.
As in most Coincident designs, the crossover is
a model of simplicity. All
components are matched to within 1% tolerance, with
lead to lead
construction eliminating the need for wires, circuit
boards or connectors.
This results in a direct signal path so as to render
an uncorrupted musical
signal.
Most loudspeaker designers know that the components
used in a loudspeaker
are only as good as the enclosure(s). The GV's cabinet
is the largest in the
Coincident line-up but its construction is as unyielding
and inert as one
might expect to find in small enclosures. Blume
employs a complex array of
computer-designed vertical and horizontal braces
(10 horizontal and 5
vertical) and incorporates this arrangement with
one inch MDF hardwood and
spline joint construction (our stethoscope and knuckle
tests confirmed
this). All the above is part of good design technology
and, certainly, the
specifications read like a blueprint for an ideal
loudspeaker: frequency
response is from 28Hz to 40kHz (don't need a super
tweeter); impedance is 8
ohms (according to Blume the impedance never drops
below 7.3 ohms or rises
above 10 ohms); sensitivity is 100 db @ 1w/metre;
look at the system's power
requirements with 1.5 watts (small tube amps) to
300 watts or more. Specs,
however, do not make music and it is important to
listen toŠ
The Sound:
Unlike most Coincident designs, the GVs are 8 ohm
loudspeakers which
translates to a nice'n easy load for any vacuum
tube amplifier. What makes
these speakers sing is not power, as in watts per
channel, but a quality
amplifier with a beefy power supply to duplicate
proper dynamics as one
would find in a live performance. As it happened,
we had just two such
amplifiers in-house to use in this evaluation‹the
Wyetech Labs Sapphire and
the new Perreaux integrated unit, both reviewed
in this issue. To check
compatibility with other designs, we also used the
Bryston 7B SST monoblocks
(reviewed in Vol. 14 #2), the Copland integrated
amplifier (80 watts/
channel) and the British Tube Technology integrated
amp (70 watts/ch),
reviewed in this issue. Our in-house Wyetech Labs
Opal preamplifier was used
where needed and our source components were the
Audio Aero Capitole
(reviewed in Vol. 15#2) and the Chord DAC64 and
matching transport‹the Blu
(also reviewed in this issue). Wiring was done with
Nordost Valkyrja speaker
cables and interconnects.
Before we began our auditioning sessions, we operated
the GVs continually
for three days using our in-house Magnum Dynalab
MD 108 tuner for burn-in.
This is an important step before serious listening
as the ribbon tweeter
used here must be in optimum operating condition.
For our first auditioning session, we used the Wyetech
Labs monoblocks and
almost instantly became aware of the GVs ability
to deliver wonderfully
rich- sounding bass. Our favourite discs to check
deep bass are Todo Sobre
De Madre and Sept Paroles Du Christ. The loudspeakers
managed to reach all
the way down to a well resolved 28Hz, but allowed
us to hear harmonics above
and below. We consider this an accomplishment not
often found in loudspeaker
designs and an augmentation to the term ³musicality².
Good bottom end
harmonics correctly disclose the (different) structure
of harmonics of, say
a kettle drum, a double bass or an electric bass‹and
the Wyetech Labs
amps/Grand Victory system did this without unpleasant
side effects, such as
booming or lack of firmness.
Midrange clarity is of the utmost importance as
most musical material and
voices fall into this segment of the frequency range.
We believe it was J.
Gordon Holt who once said that a loudspeaker without
proper midrange is not
a loudspeaker at all‹and our Editor agrees.
However, the GVs quickly
established that they can deliver even the most
complex program material.
One of our favourite tracks to test this is a tune
called ³Emily² on the
JVCXR disc featuring Zoot Sims. As the nickname
implies Zoot is a master of
the baritone saxophone and when done right, listeners
can hear Zoot's saliva
passing through the mouthpiece and reed assembly
on the sax. Female and male
vocals are also enlightening when evaluating midrange
information and a lot
of loudspeakers do this very well. However, few
can delineate the
differences in tonal gradations between a baritone
and a tenor or a soprano
and mezzo soprano as well as the Grand Victory speakers.
High frequencies are often misunderstood and they
tend to be the source of
contention for many folks. Some like it hot, some
like it soft, some like it
smooth and some like it hard. However, preferences
are usually based on
personal taste‹or more precisely on what the
subconscious mind has learned
to accept as proper. As reviewers, we do not have
the luxury of choosing
what we like, but have the obligation to inform
our readers of what to
expect. The ribbon used in the GVs can produce up
to 28kHz, but the speakers
require about 30 minutes of operation before the
tweeters settle down to
their ultimate operating condition. However, once
burned in, we noticed
quite similar performance characteristics to the
Total Victory model
(reviewed in Vol.15 #2): razor-edge resolution in
midrange and high
frequencies. We'd like to subdivide the GV's performance
in the range from
about 160Hz to 1300Hz as the lower midrange, from
1300Hz to about 2,600Hz as
pure midrange and the segment between 2,600Hz to
about 5,000Hz as upper
mid/lower high segment. The GVs performance is nothing
short of revealing as
it turns up every nuance of the program material
in the upper and pure
midrange frequencies. We feel that the speakers
provide a little less energy
in the lower midrange than in the segments above
and below, but didn't find
this too important as program material didn't seem
out of musical
proportion. Besides, connected to the Perreaux integrated
amplifier, this
tiny nitpick was not apparent. All in all, Blume
has produced a loudspeaker
system that delivers almost as much superb audio
as one would get from the
more expensive model, the Total Victory.
Synopsis & Commentary:
Every loudspeaker has a personality that stands
on its own, but similarities
are apparent with almost all solidly engineered
designs from the same
manufacturer. Coincident Technology loudspeakers
sport an audible
affiliation with one another, and though the all-round
sonic signature is
shared by most models, there are many slight variations
between them. Blume
has not made a second rate loudspeaker since we
began reviewing his designs,
about 10 years ago. In fact, over the years, he
has marketed a number of
superb designs and we feel that the Grand Victory
is but one more. These
loudspeakers are a little more system-dependent
than some of the other
models and benefit more from powerful amplifiers.
The best sound was
achieved with the Perreaux amplifier, just slightly
more refined than our
second choice, the Wyetech Lab Sapphire monoblocks.
The Bryston 7B SST
monoblocks and the Tube Technology integrated amplifier
came in a close
third in the overall performance rating.
