Asbury Church in Oklahoma has replaced its aging sanctuary sound system with an L-Acoustics L-ISA Immersive Hyperreal system designed by AV systems integrator DC PRO. The installation addresses inconsistent coverage in the room while supporting two substantially different production formats on Sunday mornings.
Organized in 1962 with nine members, Asbury Church now draws approximately 3,300 worshipers each week. Its regular schedule includes a traditional choir-and-orchestra service at 9:00 am, followed by an amplified worship-band service at 11:00 am. The church also holds combined events that can require as many as 126 active console inputs, placing different demands on the venue’s audio infrastructure.
One system for two service formats
Before the project, the sanctuary’s original system had reached the end of its operational life. The room experienced uneven audio coverage, high-frequency dead spots and areas of excessive power caused by overlapping loudspeaker arrays. Those conditions required the technical team to make ongoing adjustments to compensate for the room’s inconsistencies.
Asbury began working with DC PRO in early 2025. After reviewing designs from multiple audio manufacturers, the integrator specified the L-ISA Immersive Hyperreal system. Its 360-degree surround configuration uses frontal and surround arrays, allowing engineers to position audio objects around the auditorium rather than relying only on a conventional left-right presentation.
That approach also changes how the production team handles the short interval between the two Sunday services. Instead of retuning a conventional stereo system for each musical format, staff can recall a different spatial scene. The same installed system can therefore be configured for the choir-and-orchestra service and then adapted for the worship band later that morning.
System components and coverage strategy
The installation’s main frontal array uses five L-Acoustics L2D enclosures to form the core L-ISA Scene. Kiva II and Kiva IIi side extensions broaden the coverage arrangement, while the overall system also incorporates KS21i and X Series loudspeakers.
| Installation element | Role described for the project |
|---|---|
| L-Acoustics L-ISA Immersive Hyperreal | 360-degree immersive audio configuration for the sanctuary |
| Five L2D enclosures | Main frontal array and core L-ISA Scene |
| Kiva II and Kiva IIi | Side extensions for wider coverage |
| KS21i and X Series | Additional loudspeakers included in the installed system |
- The system supports choir-and-orchestra, amplified-band and combined-event production.
- Spatial scenes can be recalled for the different services.
- The design replaces a system associated with uneven coverage and high-frequency dead spots.
For the church’s technical team, the project is centered on repeatable operation as much as on the loudspeaker inventory. The system is intended to provide a consistent spatial soundfield across the sanctuary while allowing the production staff to move between contrasting musical presentations without rebuilding the system for each service.
The installation gives Asbury a single audio platform for its weekly schedule and larger combined events. It also represents a move from compensating for coverage problems through repeated adjustments toward using an immersive system layout and recalled spatial scenes as part of the venue’s normal production workflow.
