Alcons Audio Pro-Ribbon Loudspeakers
|Surefoot Sound, LLC is proud to be
part of the Alcons Audio Team, our personnel participate in National
Trade Show Events and Demonstrations, and we stage Alcons Audio
Demonstrations of our own in the Central third of the US. We are
authorized to demonstrate, sell, and install Alcons systems anywhere in
the US. We do respect the territories of other Alcons dealers and work
with them cooperatively.
Our installed Alcons System base is growing, we'll highlight some here.

|A primer on Pro-Ribbon High Frequency drivers|
|Alcons Audio Pro-Ribbon drivers, in
contrast to other ribbon drivers, exhibit very wide horizontal
dispersion patterns (actual 90 or 120 degrees depending on product and
application), and very narrow (15 degrees
depending on array configuration) vertical patterns making them ideal
for line array and line source applications.
With very low moving mass and none of the compression chamber introducing distortion found in compression drivers, Pro-Ribbons easily reach 20khz with no listener fatigue.
When wider horizontal dispersions are required (up to 120 degrees) a "morpher" waveguide is added to open the horizontal pattern further.
When wider vertical dispersion is required (such as in point source or constant curvature applications) a waveguide with vertical pattern expansion as well as horizontal pattern expansion is used, and asymmetrical patterns (wider vertical dispersion on the bottom of the pattern) can also be realized.
|Pro-Ribbons are slightly less
efficient than compression drivers. However, in their ideal passband
they are capable of handling greater power to bring them into parity
with compression drivers without attendant distortion. See this
recent detailed test
of the LR18 Line Array by Production Partner for more information. It's worth your while.
From the tiny 4" ribbon of the LR7 line array, the LR18 Line Array, the massive 14" ribbon of the LR28 Arena Line Array or the 18" ribbon of the QR36 line source array column, or any of the Alcons Pro-ribbon products, Pro-Ribbon drivers shine.
