3.6 COMPLEMENTARY FILL SYSTEMS
For flown V-DOSC configurations, additional speakers are typically necessary to cover center fill, front
fill or offstage fill requirements and delay systems may be required for large format festival or stadium
sound reinforcement. Apart from providing added coverage, an important sound design consideration
for complementary fill systems is audience image localization - especially for theatrical applicatons
where the addition of centre cluster, front fill and underbalcony delay systems can help focus audience
attention to the action onstage.
Note: All L-ACOUSTICS loudspeakers and OEM factory presets are specifically designed to have a
compatible sonic signature. For this reason, L-ACOUSTICS enclosures provide the best complementary fill
system solutions and are recommended for use with V-DOSC.
3.6.1 FRONT FILL
In many cases, dV-DOSC downfill enclosures and/or a flown centre cluster using ARCS (inverted),
KUDO (110 degree K-LOUVER setting) or dV-DOSC will provide adequate coverage for the closest
members of the audience, however, image localization and coverage can be further enhanced with the
addition of a dedicated front fill system.
Front fill can be provided via stacked stereo infill systems using dV-DOSC, ARCS or KUDO
loudspeakers. Alternatively, a distributed approach can be adopted using dV-DOSC or MTD, XT
coaxial enclosures (see the MTD XT SPACING worksheet in ARRAY 2004 for a utility that calculates
optimum distributed front fill enclosure spacing based on throw distance). Wherever possible, front fill
systems should be physically located close to subwoofers in order to provide closest members of the
audience with some mid/high information (to help offset the exaggerated LF contour when located
directly in front of the subwoofer stacks).
