KEMPTON PARK, SOUTH AFRICA — In a landmark development for pro-audio deployment across the African continent, the Maranatha Community Church has officially inaugurated its striking new 5,500-seat auditorium in Kempton Park, South Africa. At the heart of this massive architectural and acoustic undertaking is a state-of-the-art L-Acoustics L-ISA immersive sound system—marking the very first permanent installation of its kind in Africa.
Engineered and supplied by prominent regional AV distributor DWR Distribution, the comprehensive audio ecosystem leverages cutting-edge A Series loudspeakers, KS28 subwoofers, and sophisticated spatial fill architecture. The result is a transformative acoustic experience that delivers pristine, localized sound to every single seat in the expansive venue, including challenging listening zones tucked deep beneath the newly constructed balcony.
Main Facts
The unveiling of the 5,500-seat auditorium represents a monumental physical and technical expansion for Maranatha Community Church, nearly doubling the capacity of its legacy 3,000-seat facility while introducing a sweeping architectural balcony to accommodate its growing congregation.
Rather than settling for a traditional, legacy stereo reinforcement model, the church partnered with DWR Distribution to deploy a fully realized L-Acoustics L-ISA immersive sound configuration. The hardware footprint is substantial, designed to handle high-energy contemporary worship services without compromising on fidelity, clarity, or headroom.
The core system architecture features:
- Main Arrays: Five central A15i arrays, each outfitted with six A15i Focus enclosures.
- Extension Arrays: Two dedicated extension arrays, each comprising six A15i Focus enclosures to widen the soundstage.
- Low-End Reinforcement: Eight KS28 subwoofers flown directly above the stage in a tightly controlled cardioid configuration to manage low-frequency dispersion and keep the stage clean.
- Fill and Delay Zones: Two A15i out-fill arrays, two A10i Focus delay speakers, and 10 5XT front fills operating in mono to cover peripheral zones outside the primary immersive sweet spot.
- Under-Balcony Spatialization: Twenty X6i loudspeakers deployed specifically as spatial fills to preserve the continuous 3D audio image for patrons seated beneath the overhang.
- Processing & Amplification: The system is powered and managed by an advanced rack-room setup featuring two LA12X, six LA7.16i, and one LA4X amplified controllers.
By routing individual console channels directly into the L-ISA Processor II, sound engineers can place instruments and vocalists spatially within the virtual soundscape. What the congregation sees on stage directly aligns with what they hear, drastically reducing acoustic masking and mud often associated with high-decibel amplified worship environments.
Chronology: From Concept to Commissioning
The realization of this groundbreaking installation was a meticulous, multi-year endeavor that required careful planning, rigorous acoustic modeling, and precise on-site execution.
Phase 1: The Initial Vision and Open-Ended Brief
When the expansion project first commenced, there was no fixed audio brief. Robert Grobler, a seasoned lighting designer and long-standing church member who has been involved with Maranatha since 2007, stepped into the role of project consultant. Working hand-in-hand with DWR Distribution, Grobler’s primary objective at the outset was simply ensuring adequate power and uniform coverage.
“There was no fixed brief when the project began,” recalls Grobler. “They wanted a system with enough power. People worship here, and it gets loud. L-ISA wasn’t even on the table at first. It was just about finding something that could cover the whole room properly.”
Phase 2: The Two-Year Evaluation and Soundvision Modeling
Over a nearly two-year period, the technical team at DWR Distribution evaluated several prospective sound system options. Every potential design was subjected to rigorous computer modeling using L-Acoustics’ proprietary Soundvision software to simulate coverage, SPL distribution, and frequency response across the irregular geometry of the 5,500-seat hall.
The pivotal turning point for the church leadership occurred away from the drawing board. After experiencing the immersive capabilities of an L-ISA system firsthand during a Jonathan Roxmouth concert at Montecasino—where the setup was deployed by Multi-Media—the decision-makers were instantly converted.
“Once they’d heard it for themselves, there was no turning back,” notes Richard Smith of DWR Distribution.
Phase 3: Installation, Alignment, and Calibration
With the system selected, physical installation began under the guidance of DWR’s expert personnel, including Jaco Beukes and Kyle Freemantle. They worked in tandem with L-Acoustics application engineer Adriaan van der Walt, who collaborated on the initial design phase before returning to South Africa to calibrate the hardware and oversee official commissioning.
The physical rigging and alignment demanded absolute precision. Because immersive audio relies heavily on exact physical positioning relative to virtual panning, millimeter-level accuracy was mandatory.
“The real complexity sits in the L-ISA controller, where the routing and positioning angles have to be exact,” explains Kyle Freemantle. “Getting the rigging precisely right was hard work, but genuinely enjoyable.”
Adriaan van der Walt echoed this sentiment, praising the local team’s craftsmanship: “The information exchange from the initial design through to verifying speaker positions and angles on site was meticulous. Hats off to them.”
Supporting Data & Technical Infrastructure
To truly understand the leap forward that Maranatha Community Church has taken, one must examine the acoustic challenges inherent to modern houses of worship seating thousands of people. Large-format spaces frequently suffer from slap-back echoes, phase cancellation, and the dreaded "wall of sound" effect typical of traditional left-right stereo PA deployments.
In a standard stereo configuration, audience members sitting off-center experience an unbalanced mix, hearing predominantly the nearest speaker stack. Furthermore, as multiple vocalists and instruments compete for space within the left-right channels, mixers often rely on heavy EQ and compression, squeezing the dynamic life out of the performance.
The L-ISA ecosystem fundamentally alters this dynamic through object-based mixing:
- Source Localization: Sound objects are assigned spatial coordinates (pan, width, depth, and height). The L-ISA Processor II distributes discrete signals to the five main A15i arrays and extension arrays.
- Acoustic Transparency: Because audio sources are spatially separated in the room just as they are on stage, the human ear can naturally distinguish individual instruments even during dense, high-volume arrangements.
- Comprehensive Coverage Mapping: Soundvision modeling ensured that even with the introduction of a massive balcony, the 20 under-balcony X6i spatial fills seamlessly blend with the direct sound from the stage, maintaining timbre, intelligibility, and imaging continuity.
- Amplification Efficiency: The combination of LA12X, LA7.16i, and LA4X amplifiers provides immense dynamic headroom, ensuring that the system can effortlessly deliver impactful low-end transients from the KS28 subwoofers while maintaining pristine high-frequency articulation.
Official Responses and Perspectives
Key stakeholders, technical consultants, and church leaders have shared glowing assessments of the new venue and its revolutionary audio core.
Pastor Mark Bradshaw (Overseeing Music and Training):
Pastor Bradshaw has been particularly vocal about how the transition to immersive audio has impacted the church’s creative ministry.
"With stereo you get a wall of fairly generic sound coming at you," Bradshaw observes. "With L-ISA, if the drums are on the left, the sound comes from the left. What you see is what you hear, and that separation makes everything clearer, and easier on the ear."
He further emphasizes the psychological and emotional boost the system provides to the performers on stage:
"We have a great team, and every musician, every vocalist, wants to be heard. That’s why you become a musician in the first place. Now they’re heard, because there’s space for them."
Richard Smith (DWR Distribution):
Reflecting on the journey from traditional audio concepts to pioneering multi-channel sound in Africa, Smith highlights the paradigm shift experienced by everyone involved in the evaluation process. The moment the church leadership heard the technology in action at Montecasino eliminated any lingering hesitation regarding the complexity or cost of an immersive deployment.
Adriaan van der Walt (L-Acoustics Application Engineer):
Looking toward the future, van der Walt stresses that the physical installation is merely the foundation. He anticipates that as the church’s in-house technical crew spends more time operating the console and the L-ISA controller, they will unlock creative avenues that engineers have yet to conceive.
"This is the starting point for the venue crew," says van der Walt. "L-ISA is new to them, but once they’ve had training they’ll find ways to use the system none of us has thought of yet."
Implications for the Regional Pro-Audio and Worship Sectors
The successful deployment of the L-Acoustics L-ISA system at Maranatha Community Church carries significant implications for the broader professional audio landscape in South Africa and the wider African continent.
