ABOUT REVEL CONCERTA2
LOUDSPEAKERS SERIES
Thank you for purchasing Revel Concerta2 loudspeakers Series
speakers. These true full-range loudspeakers feature small footprints
and sleek designs, allowing them to blend-in easily with your existing
décor. They deliver an impressive combination of wide frequency range,
uncompressed dynamic range and low distortion across the entire
audible spectrum.
Typical tweeter magnetic assemblies have a small space behind the
dome that causes a high mechanical resonance. In designing the
Concerta2 series, this challenge was met head on by Revel engineers.
They created a tweeter mechanical resonance that is well below the
operating band which would ensure linearity and consistency at the
crossover frequency. To do so, a large cavity behind the magnetic
assembly is vented around the perimeter. This, along with a compliant
diaphragm surround, sets the mechanical resonance frequency to a low
800 Hz compared to a typical 1.5 kHz found in similarly priced speakers.
These advances allowed the tweeter/midrange crossover to be set an
octave lower thereby improving the system directivity.
By repositioning the voice coil in the woofer, Revel engineers discovered
they could improve the symmetry of the woofer displacement and
thereby lower distortion. Also, asymmetry attributed to spider non-
linearity can also lead to higher distortion. This was solved by adjusting
the spider progression to greatly improve the symmetry and as a result,
lowered distortion.
A novel technique of cabinet construction was used to create Concerta2
enclosures that were not only beautiful, but also have the rigid, curved
side walls plus extensive bracing that results in a strong and inert
enclosure. This ensures no cabinet coloration to the sound. The
attractive designs are also painted a high gloss white or high gloss black
finish, have magnetic grilles and show no visible fasteners, features not
typically seen on speakers at this price point.
Revel Concerta2 crossover networks feature carefully-selected
components that contribute to great performance and benchmark
setting value. These high-order crossover networks dramatically reduce
distortion and dynamic compression for clear sound that maintains the
same quality over a very wide dynamic range. These precision networks
optimize the speakers' timbral accuracy, enhancing musical enjoyment
for listeners who are anywhere in the room, not only those seated on-
axis to the loudspeakers.
During development, every Revel loudspeaker model is compared to
competitive models in our unique position-independent double-blind
listening lab. This process utilizes the latest psychoacoustic research
to assure that these listening tests are valid, enabling us to verify that
all Revel loudspeakers are superior to their competitors before they are
allowed to go into production.
