INTRODUCTION
The ENTASYS Full-Range column can also be modified to provide a range of coverage patterns. The horizontal coverage is a
very consistent 120 degrees, while vertical coverage is easily reconfigured. Nominal vertical beamwidth is 12 degrees in its
default "curved" configuration (as shipped). This beamwidth can be narrowed in the midrange and high frequency regions by
replacing the smaller stand-offs behind the midrange/high frequency driver modules with the larger 34.2 mm spacers included
with the loudspeaker. This "straight" configuration will alter the nominal vertical beamwidth to 6 degrees. The loudspeaker
may also be configured as "asymmetrically curved" by replacing the stand-offs at half of the column. In this manner, a vast
number of coverage combinations with shaped vertical coverage patterns can be achieved using various modular
configurations. Refer to the ENTASYS Installation/Operation Manual for details on making these modifications.
For most applications comprising a single ENTASYS Full-Range column, the curved configuration is recommended.
When two Full-Range columns are arrayed immediately above and below each other, optimal performance will be achieved
using the straight configuration for each column. The top of the upper column and the bottom of the lower column could
remain curved. This will yield a symmetrical array when assembled.
ENTASYS Full-Range modules offer exceptionally tight vertical beamwidth and excellent vertical directivity control. The
beamwidth begins to widen in the lower frequency regions below 1 kHz; this is not unique to ENTASYS, but rather is
consistent with the laws of physics for a line array with the height of a single full-range column. The beamwidth in this lower
frequency region can be significantly narrowed, to virtually match the beamwidth at higher frequencies, by adding ENTASYS
Low Frequency columns to the array. Adding ENTASYS Low Frequency columns can be a much more cost effective solution
than adding more Full-Range columns, making it possible to achieve the required pattern control and SPL in the lower
frequency region while using a limited number of Full-Range modules.
Part of the superior performance of ENTASYS is due to its internal passive crossover. This crossover employs high order
slopes, passive equalization, and proprietary design techniques to integrate each cabinet's sixty-six drivers into a single radiating
line array to deliver a broad frequency range.
Low Frequency Column (ENT-LF)
The ENTASYS Low Frequency column is visually externally identical to the Full-Range column. Both FR and LF units are
designed with the same enclosure, grille, input connectors, etc., resulting in a seamless aesthetic design that blends
unobtrusively with any environment.
Internally, the Low Frequency column contains no midrange or high frequency drivers, nor the passive crossover circuitry for
these drivers. Instead, it is designed with its own passive low pass filter, optimized for seamless integration with the Full-Range
or other Low Frequency columns in an array.
Note that the Low Frequency column is not intended as a low frequency extension device or a subwoofer. It is designed to
augment the maximum output level of the low frequency pass band for ENTASYS, as well as enhance its vertical directivity
control. To maintain this directivity control, the Low Frequency column should utilize the same external high pass filter as the
Full-Range column when multiple columns are employed (reference Page 17).

Custom Painting

ENTASYS systems are available as standard items with a black or white powder coat finish. Custom colors are available upon
request and approval from Community. The powder coated aluminum enclosure may be painted using standard off-the-shelf
paint suitable for use on powder- coated surfaces. The nylon end caps cannot be painted with this type of paint. These should
be painted with Krylon® Fusion for Plastic®, Plasti-Kote® Plastic-Bond Enamel, or Rust-Oleum® Plastic paint specifically
formulated for use on plastic parts. Alternatively, the enclosure may be coated first with a plastic surface primer such as
Plasti-Kote® Plastic Primer or Rust-Oleum® Plastic Primer. A second coating of paint may then be applied on top of the
primer coat.
ENTASYS grilles are powder-coated steel. To paint the grille, carefully remove the cloth backing and use paint that is
compatible with powder coating. Do not paint the cloth. Apply replacement grille cloth (available from Community) by using a
fine mist of spray adhesive on the grille. Do not put adhesive on the cloth. Then, attach the cloth by pressing it onto the
interior surface of the grille. Be careful not to clog the pores in the cloth.
