Renaissance
The Renaissance (R-3 plus R-4) loudspeaker
system is a premium
electrostatic panel that
provides the ultimate in versatility and small panel performance. The mission of the
Renaissance is
to provide the finest acoustical reproduction from the lower mid-range to the
highest audio frequencies. A single piece-wise curved membrane provides a
cohesive sound source that is free from the anomalies created by the use of
multiple drivers. Dispersion is an amazing seamless 90 degrees in the horizontal
plane, making the entire listening room the "sweet spot". What's
more, the Renaissance
has a higher efficiency than is
normally expected from an electrostatic speaker, making possible the use of lower-powered amplifiers. The
Renaissance
has four
controls to equalize and optimize sound reproduction: one control permits
a choice of four gain positions, a second control permits a choice of four
mid-frequency levels. A third control, brilliance,
permits adjustment of the high-frequency balance. Finally, a fourth
control, bias, allows optimal adjustment of efficiency.
The R-3 portion of the Renaissance is not intended to reproduce the lower
two octaves of the audio spectrum. The choice of a low-frequency
transducer system, or sub-woofer, is left open so that bass characteristics can
be selected to meet the desired criteria of the application. It has been
our experience that some listeners prefer a fast articulate bass characteristic
while others prefer a heavy, less defined characteristic. The demands of
serious music listeners tend to prefer the former while those having interest in
the reproduction of explosive special-effect sounds of video tracks prefer the
latter. Sound Lab offers a special matching sub-woofer, the
Rennaisance-4 (R-4). The R-4
is designed to provide an excellent balance between these characteristics.
If a sub-woofer is desired that can perform acceptably over a variety of
situations, we recommend the R-4. However, if
the application requires fine-tuning for a specific application, then the
appropriate bass unit can be independently selected. If it is desired to
employ a special-purpose sub-woofer, then just the
R-3
is purchased, which has it's own free-standing base. When the R-4
is employed, it mounts to the lower back of the R-3,
forming a monolithic structure. In this case, the free-standing base is
not necessary and the R-3 is purchased without it.
The Renaissance
represents over a quarter of a
century of electrostatic loudspeaker development. Nothing has been spared
to provide the absolute finest in electrostatic reproduction and application
versatility.
