The object is to prevent sound reflection back to the point of
origin until after several reflections and/or after being
considerably attenuated. Once again if you feel having a
standing wave problem in your room, please consult your
dealer to get proper assistance in this matter
Early reflections are the first sound reflections heard at the
listening position. They are usually intense and annoying. In
order of importance, they usually come from the floor, the side
walls and the ceiling. They can either be controlled by placing
diffusors or absorbers at their image location. Your dealer can
be of good assistance in properly helping you with this matter.
In an already well damped room, we recommend utilization of
diffusion instead of damping.
If you choose to work with a specialized room treatment
device, the included manufacturer’s instructions should be
followed.
Your new Fidelio is an extremely precise instrument that can
clearly reveal the qualities of your upstream equipment. Your
Fidelio performance will be closely related to the excellence of
its associated equipment. Subsequently, it would be wise to
invest in high-quality, ancillary equipment as your enjoyment
will be consequently rewarded.
The Fidelio shows an easy impedance load for most power
amplifiers. It has been evaluated with a wide variety of power
amplifiers and showed consistent results with quality solid state
and vacuum tube equipment. Superb performance can be
realized from either design.
The uniquely designed and manufactured binding-posts on the
Verity Audio Fidelio accept banana plugs, spade connectors or
bare wires. For best results, we recommend the use of spade
connectors.
When choosing speaker cables, experimentation is the best way
to find which ones will be the most satisfying in your
installation. Your Verity Audio Dealer can be of assistance in
making recommendations.
Power Handling
The Fidelio offers an outstanding power handling capacity and
yields astonishing dynamics.
The power tolerance of a loudspeaker is correlated to its
maximum voice-coil heat dissipation and to its maximum cone
displacement. These parameters are in turn stimulated by the
time, amplitude and spectral characteristics of the applied
musical energy. At low-frequencies, the maximum cone
displacement is normally reached before maximum voice-coil
temperature.
With the Fidelio transducers, because of their superior
ventilation system, the voice-coils will most likely never reach
critical temperatures. But, low-frequencies played at high levels
can ask for larger cone displacement than allowed by the
driver suspension. A driver reaching its maximum
displacement will not break unless this situation is maintained
for an inordinate period of time. Before a driver reaches its
maximum displacement, its distortion level will increase
greatly and will become audible. So when a speaker starts
sounding bright and hard or if any “cracking noise” can be
heard, just lower the level until it sounds comfortable again.
The Fidelio has to be played unexpectedly loud before any
occurrence of compression or distortion.
Cabinet Resonance
Cabinet resonances are controlled in a very special way. Their
amplitudes are lowered and their frequencies are increased.
Because higher frequencies are more directional, it will be
most unlikely that they get the chance to reach the listening
point. Of course, the listening room has to be properly treated.
Also, traveling high-frequency sonic waves attenuate faster than
their low frequency counterpart. A unique cabinet bracing
arrangement can break a wall resonance into multiple higher
frequency resonances that are not harmonically related. By
doing so, their amplitudes are greatly reduced. The cabinet
construction tolerances are so tight that only computer-
controlled tooling can cut panels with acceptable accuracy.
The cabinet rigidity lowers even more any chances of
coloration caused by unwanted vibrations. Special materials
are used to ensure stability of the cabinet in any acoustical
environment.
Care of the Finish
The high-gloss exotic wood veneer and black piano finish
available for the Fidelio is composed of high-grade Italian
lacquers. You will only find them on luxury pieces of furniture.
They are long-lasting finishes and need little care.
Never use any solvent or abrasives to clean your speakers. To
remove fingerprints, use a lint-free cloth moistened with a few
drops of water.
Use a cloth brush to clean the front panel black velvet. A
transparent packing tape works also very well.
The Verity Audio direct gold-plated solid-copper binding posts
have been specially designed to introduce a very low
impedance path for high-power signals. To keep it at its best,
we recommend cleaning them every year with one of the
special contact cleaners available on the market. The best
results can be obtained from products that have been specially
formulated for gold-plated connectors.
