Ribbon Emulator, a device that allows a line of 1-inch drivers to effectively produce a single ribbon of energy. The spacing of the drivers used in ENTASYS has been optimized for the frequency region that they reproduce to minimize the formation of grating lobes in the vertical plane. - Page 15 The low frequency column is not intended as a low frequency extension device or a subwoofer. It is for use to augment the maximum output level of the low frequency pass band for ENTASYS as well enhancing its directivity control in this frequency region. This is illustrated by comparing the vertical directivity map of a single full-range column (Figures 2) with a full-range and two low frequency columns (Figures 3).

Connecting Individual Loudspeakers in an Array to Separate Amplifier Channels For arrays that contain more ENTASYS loudspeakers than can be driven from a single amplifier channel, multiple amplifier channels should be used. Ideally, the same amplifier model (and settings) should be used to drive each loudspeaker. -
Page 41: Table 11: Recommended Cable Gauge
INSTALLATION Cable Type and Gauge Community recommends stranded, twisted-pair loudspeaker cable. Insulation should be rated for 600 volts or higher. For outdoor installations, choose a cable designed for the application. For permanently installed systems, a slick, vinyl type insulation is easier to pull through conduit. For portable applications, a rubberized type insulation is more flexible. -
Page 42: Rigging/Suspension And Safety
WARNING - NON-COMMUNITY RIGGING HARDWARE: Non-Community hardware used for rigging an ENTASYS loudspeaker must be certified by the supplier for this use and must be properly rated for safety. Important Notes on Rigging Loudspeakers There are three areas of responsibility for rigging loudspeakers. -
Page 43: System Design Guidelines
ENTASYS grilles are powder-coated steel. To paint the grille, carefully remove the cloth backing and use paint that is compatible with powder coating to paint the grille. Do not paint the cloth. Contact Community for replacement grille cloth. Apply the grille cloth by using a fine mist of spray adhesive on the grille. (Do not spray adhesive on the cloth.) Then, attach the cloth by passing it onto the interior surface of the grille. -
Page 44: Figure 25: Entasys Full-Range Curved & Straight Configurations
The curved configuration uses three other size spacers (31.4 mm, 23.2 mm, and 9.5 mm) in addition to the 34.2 mm spacer. To reconfigure ENTASYS to the straight configuration remove each mid/high frequency module and replace each of the smaller spacers with a 34.2 mm spacer. -
Page 45: Table 12: Frequency, Wavelength, Column Size, And Directivity Control
Table 12 shows the relationship between frequency, wavelength, the size of single and multiple column ENTASYS arrays, and the directivity control expected. When the line length is approximately four times the wavelength (or greater) at a given frequency, the directivity control should be good at this frequency. When the line length is approximately two times the wavelength at a given frequency, the directivity control will be decreasing but acceptable. -
