This system design template describes a typical loudspeaker system for a smaller-sized performance venue with slightly sloped seating. It may not present difficult acoustics, and might benefit well from either a point-source or line-source system. In this case, an IV6 Modular Vertical Array offers a wide range of capability from soft, articulate presentations to high impact music. The adjustable directivity offers the opportunity to tailor the coverage to exactly the shape of the space, maximizing the listener's experience and keeping music clear at all sound pressure levels.
Two (mirror image) IV6 short arrays (increasing curvature from top to bottom) cover the entire space providing even SPL throughout by utilizing our Passive Acoustic Optimization tool in EASE® Focus 3. Each array will include  1122/05 and  1122/15 elements. Additional IV6-1122/15 front fills will provide localization for patrons near the stage. To provide additional bass coverage in the space, two pair of subwoofers are positioned on their side panels back-to-back to maximize output while maintaining aisle space for the patrons in the front row.
Combining both types of IV6 array elements allows the array to address both close and far seating from a low trim height. Tightly packed 5-degree modules at the top focus sound to the rear seats while the bottom 15-degree module wraps coverage down to the front rows that are very close to the stage. Passive attenuation assigned to modules in the array further smooths out the coverage uniformity. To provide even bass coverage to all patrons, the subwoofer array uses slightly different delay and low pass settings to prevent narrowing the low-frequency coverage. This approach can apply as a design strategy for similar venues with wide prosceniums and a need for multiple subwoofers (for higher output).
Below is the list of Community equipment used in this design:

Amplified Loudspeaker Controllers
Biamp's line of Community Amplified Loudspeaker Controllers (ALC) are the recommended amplifiers for this application. They offer factory-optimized DSP processing, protective limiting and amplification, as well as signal routing, zone switching, and remote monitoring for virtually any Community loudspeaker application.
Standard Ethernet communication protocols allow for fast system design, system control, and remote system monitoring. Analog and Dante® inputs included in each model are assignable per channel in static or failover/backup configuration, supporting quick and easy integration into any new or existing system.
Community-authored loudspeaker presets include equalization, high pass filters, and multi-stage limiters tailored to each model, ensuring consistent sound quality and full loudspeaker protection in every application. Additionally, each Community loudspeaker preset includes loudspeaker power and impedance information, allowing the system configuration software to display the total power and impedance of multiple parallel wired loudspeakers, further reducing the time and effort required to match complete loudspeaker systems with the appropriate ALC models and output channel configurations.
In-depth control and monitoring is accomplished via ArmoníaPlus® system manager software.
