Description
The Van Medevoort ED7.2. Reference speaker system with electrostatic
mid-high unit. Slim lined floor standing model in line-source version.
Due to its special design, this loudspeaker is very suitable for any
listening room, the living room and even a more spacious living room.
The model is made up of two segments, whereby the closed low cabinet is
internally equipped with our exclusive vM Anti-Resonance sub-low system.
This has further improved the 'low'. Less compression, a fuller bass,
more openness and quietness in the mid-range. The "high" is placed phase
linearly next to the "low", whereby the slim ESL unit is equipped with
an acoustic lens for greater wide dispersion and to prevent diffraction
and bundling. The radiation is very large, especially in the horizontal
plane, so that a perfect focusing and placement of the instruments in
the sound image is realized in width, depth and height. This provides an
optimal stage, even for multiple seating positions / listeners. The
loudspeakers are executed or supplied as left and right model. Perfect
reproduction quality of any genre of music reproduction at any realistic
listening level.
With the vM ED7.2 you have a compact, aesthetically designed high-end
reference loudspeaker system that reproduces any genre of music in
studio quality
Technique
The Van Medevoort ED7.2 is made up of two segments, where the 'high', an
electrostatic line source mid-high unit with a surface of 50x1250mm, is
placed phase-linearly as a dipole next to the 'low'. This vM ESL unit,
constructed with an as open as possible stator system from acoustically
dead and resonance-free material in a robust, stable HPL sandwich frame.
The bandwidth of this tall unit is much higher due to the narrow
construction. The slim housing is equipped with an acoustic lens to
prevent diffraction and bundling, so no hot spot. This is in contrast to
full-range ESLs and other wide-panel speakers. These are difficult to
place, poor bass reproduction due to acoustic short circuit, are in the
way, need a lot of space behind to prevent reflection and coloring, can
be listened to by only one person who also has to sit still, in short,
not good and very tiring hotspot. The vM ESL can be placed very well in
any listening room for perfect stereo imaging and free from listening
fatigue. The in-house developed and manufactured symmetrical C-core
audio transformer with large bandwidth and dissipation power, connected
to special correction networks and x-over filter, makes it possible to
supply more power to the ESL with less distortion. The ESL volume is
adjustable on the high-voltage power supply unit for fine tuning in the
listening room. The closed low cabinet has been given
an optimal content for internal placement of the exclusive vM
Anti-Resonance sub-low system with acoustic filtering at 100Hz, a
technical improvement of the Isobaric configuration and already used in
the first vM speaker systems since 1985. The low-frequency dynamic
performance level is therefore even further improved. Less compression,
a fuller bass, more openness and quietness in the mid-range, in other
words the perfect match with the vM ESL. Despite its small dimensions,
the 'tactile' bass reproduction can be realized with ease in comparison
with other usually much larger speakers in the same target group. The
bass reproduction continues straight to below 35 Hertz!
With the vM ED7.2, all units per speaker system are specially
manufactured, modified and prepared to achieve maximum efficiency and
consistently high sound quality. The various electronic components for
the loudspeakers are carefully paired and matched per set, then
individually prepared. The x-over filters for high and low are
respectively placed in the high and low cabinets, the crossing point is
490Hz. This simplifies bi-wiring, with two cables from the amplifier to
improve the damping factor. Even better results are achievable with
bi-amping, two amplifiers that drive high and low separately. Always use
two amplifiers with the same phase behavior, never or usually not the
case with different techniques and brands. As is known, all vM power
amplifiers have been specially developed for ESLs, which means that they
can be matched with different models. Then use the largest amplifier for
the high, because an ESL is a more complex load than the low system. Due
to the clever size of the low housing, as well as the 'in line' executed
and inside mounted ESL high units next to the low units, so that phase
behavior and sound image are not affected. Partly because of this, a
very realistic stage, excellent focusing and perfect reproduction
quality of every music genre are guaranteed: from pop to classical and
from soloist to large orchestra or big band. |
