BEETHOVEN CONCERT GRAND
Scale, power and grandeur are all conferred by its name. As with all models in the Grand™ range, the
composer name is selected based on the scale, complexity and power of performance for which they
are best known. The term Concert Grand, like the piano of the same designation, refers to its ability to
deliver this level of performance in large concert halls and music rooms. The new 3-way Concert Grand
delivers far more than just power and scale. The careful listener will delight in the lucidity and clarity of
the all-important middle ranges where virtually all instruments find their tonic origins. Here it excels,
with a natural ease, clarity and quietness where only a few much more expensive designs have tread.
For a large-scale screening room or theater, the Concert Grand delivers even the most demanding
scenes with an ease that allows for deeper immersion into the film experience. A truly extraordinary
product that will re-calibrate your expectations.
Handcrafted enclosures in beautiful wood finishes define the Vienna Acoustics aesthetic. The Grand
Series features the following selections to complement any interior: Piano black, Maple, Cherry, and
Rosewood.
Three new 7” Spidercone bass drivers (or ULF, Ultra Low Frequency,
drivers), feature a reworked motor assembly and revised placement of
the XXP ribs, providing increased output, extension and control. The huge
surface area that results from the use of three of these extraordinary
drivers means effortless reproduction of extreme bass dynamics with
articulation and force.
All bass and midrange drivers benefit from a new inverted rubber surround
design and formulation that constitutes a breakthrough in no loss damping
of cone edge resonances.
The new 6” midrange driver benefits from a reformulation of Vienna
Acoustics’ proprietary XPP cone material. Combining TPX, the unique
thermoplastic used in all XPP cones, with three polypropylene based
synthetics, achieves maximum inner damping, ultra-low mass, and precise
control over cone density and rigidity. Dubbed X3P (X3P because of the
three additional polymers in its composition) this new cone material allows
the driver to provide an extraordinarily wide bandwidth, while possessing
a level of inner detail, quietness, and control that is truly remarkable.
All bass and midrange drivers benefit from a new inverted rubber surround
design and formulation that constitutes a breakthrough in no loss damping
of cone edge resonances.
The new tweeter was developed by Vienna Acoustics, in conjunction
with Scan Speak, resulting in greater resolution of the subtlest of high
frequency impulses while maintaining the midrange warmth and clarity
for which Vienna Acoustics has been renowned.
A completely new linear crossover layout, with the copper circuit paths
arranged in the direction of electron flow, takes into account the potential
for sympathetic and parasitic interactions among crossover components
that may inject unwanted noise and distortions while allowing for more
direct and efficient transfer of signal to the drivers which leads to a greater
level of detail and purity.
New proprietary cabling, consisting of large scale solid copper conductors,
with each cable pairing precisely twisted a prescribed number of turns for
the particular length of each cable so that any noise injection through the
wiring harness is avoided.
New gold-and-silver alloy terminal for lowest transfer resistance and
durability are directly connected to the crossover circuit board to ensure
complete current delivery and no loss of clarity in the signal transfer from
binding post to crossover
Innovative and unique grilles feature an aluminum frame that incorporates
an integral V-shaped phase diffuser to control dispersion so that they can
be left on for all but the most critical listening without an adverse influence
on performance. In fact, it can be used as an additional tuning device for
the audio enthusiast, benefiting soundstage presentation both in depth
and stereo imaging. As an additional benefit, the V-shaped groove running
the length of the middle of the grille results in a more elegant appearance
for the speaker.
Special decoupling and stability optimization through the use of a highpressure die cast aluminum spike assembly and solid steel spikes further
improve performance.
Cabinets boast massive baffles that are 1.6” thick, 30% thicker than
previous models, for maximum rigidity and resonance control.
Maple and Cherry finishes join a revised Rosewood, applied to the highest
of standards using the state-of-the-art veneer-wrapping technology for
the front and rear baffles first pioneered on the Classic series. A true Piano
Black lacquer is now available, the quality of which will permit inclusion
into any living room as it mirrors its surroundings.
