Line Array’s are the best technology for live sound but what
is lacking is the easy ability to do fine physical adjustments for each cabinet
to really “nail” the sound quality for a given venue. Live Sound Engineers dealing with reality
instead of theory will generally agree that a line array allowing minor ( or
major ) individual cabinet adjustment properly applied will improve a venue’s
sound.

Online 03/01/2001: 'John Meyer, Meyers Sound (1) : “You don't
have any control over the horizontal [coverage pattern],” notes Meyer.
“So if you have a line array that's 90 degrees, it has to fit the space
that you're putting it in. If it doesn't fit very well… We could never
use line arrays in Carnegie Hall, it's too long and narrow. You need to
be able to shape the array, so it's never going to be practical for
something like that.” '

Currently, audience members at various positions receive
sound from different parts of the array and the frequency response will not be
consistent. (2)
Line Array Manufacturers developed a variety of designs to partially minimize
frequency response problems. J Array “arc source” partially fix this coverage
and frequency-response problem by taking a portion of the line source array and
treating the portions in ways as a point source.
We do not claim to fully correct sound issues associated
with arrays but our system allows the sound engineers to have the physical
adjustment tool to help allow real sound quality improvements using line arrays
in the field.
The Venues where Line Source Arrays are used are never
ideal. True Accuracy cannot be claimed for live sound applications when it is only demonstrable on a computer
model at some specific position.
Arrays with Fixed Horizontal Cabinets create sound patterns with issues when used
in narrow areas as the sound reflects off the walls creating accuracy / imaging problems.
And array sound Vertically narrow's toward the rear of a room so the
strongest output needs to be pointed at the furthest seats— without reflecting
off the side walls. Each cabinet’s slight
individualized adjustment, a combined Horizontal and Vertical position adjustment can help customize
the sound to a venue.
Manufacturers can optionally take advantage of the
spherical cabinet shape used with the Chord designed for Horizontal/Vertical
cabinet adjustments to mount higher frequency drivers producing wavelengths which are less than
component spacing. This helps reduce accuracy
/ imaging problems due to the same drivers on various array cabinets having
different positions relative to any listener. (3)
Our design may help with...
INDOOR ARRAYS: Directive Adjustment is desirable to
further improve the ratio of direct to reflected energy at any given location.
OUTDOOR ARRAYS: Directive Adjustment is desirable for if
for no other reason that noise laws may stipulate
that sound may not bleed from a performance space into adjacent areas.

Enclosure offers 3 Pathway’s to seize the opportunity while
matching your company needs.
A. The Cradle offers your existing cabinets to have Directive Adjustment using the Chord System.
B We offer the option to use our acoustically engineered composite wall materials with your existing cabinet shapes and existing rigging system.
C Finally, Chord offers the ability to adapt your current cabinet volumes, wall-thickness, etc into a non-diffracting shape for which the Chord system was formulated.
