Situated in the heart of Auckland, the historic Anglican church of St Matthew-in-the-City has recently undergone a discreet but powerful sound system upgrade, thanks to the installation of a JBL Intellivox column array system. The heritage-listed building, constructed in 1905, is renowned not only for its stunning Gothic Revival architecture but also as a sought-after venue for weddings and community gatherings.
The need for a new system was driven by the church’s evolving role as both a place of worship and a flexible event space. As such, the brief from both the caretakers and the project architects was clear: deliver outstanding voice reproduction for liturgical use, while ensuring speech clarity and coverage suitable for a broad range of public events – all without compromising the venue’s aesthetic integrity.
Integrator Alpha Sound was awarded the contract, working in close partnership with JBL distributor JPRO and Peter Reed, Senior Consultant at Salmond Reed Architects. Given the acoustic complexity of the space with its ornate architectural features and Category A Heritage Status, the team specified JBL’s Intellivox range for a solution that could deliver intelligibility and seamless coverage.
“The challenge was to ensure high speech intelligibility while respecting the visual heritage of the building,” said a JPRO spokesperson. “We modelled the space in 3D to understand the acoustic characteristics from different column loudspeakers and then determined what the STI values were.”
With the goal of achieving Speech Transmission Index (STI) values above 0.5 – and ideally closer to 0.6 – the design team focused on directing sound only where needed, minimising reflections from hard surfaces and avoiding coverage in non-audience areas. JBL Intellivox’s beam forming capabilities proved key to achieving those objectives.
“The sleek Intellivox-DSX280 HD powered column array loudspeaker, capable of providing a constant sound pressure level up to 35m, provides consistent full-range audio from the front of the nave to the rear.”
The sleek Intellivox DSX280 HD powered column array loudspeaker, capable of providing a constant sound pressure level up to 35m, provides consistent full-range audio from the front of the nave to the rear, with minimal intrusion on the church’s heritage interior. Intellivox DSX180 powered column arrays are used as fill systems in the North and South sides. With their slim profiles and custom paint finishes, the Intellivox systems blend discreetly into the surrounding stone columns.
Due to the venue’s multipurpose use, JBL PRX815XLFW 15-inch subwoofers were added to provide additional bass reinforcement for music applications. JBL CBT 50LA column arrays, powered by a Crown CDi4300 amplifier, were deployed to deliver consistent sound coverage from front to back in the mezzanine level.
An AKG CGN gooseneck microphone was selected for the lectern, while AKG C214 large-diaphragm condenser microphones were used to capture the Bell Tower and Cathedral Organ with pristine clarity. These additions have dramatically enhanced the overall worship experience for those attending services at St Matthew-in-the-City.
“The JBL Intellivox speakers blend seamlessly into our space and the audio quality is quite astounding.”
“The outcome of the loudspeaker upgrade is remarkable,” said Dmitry Rusakov, Events Manager at St Matthew-in-the-City. “They blend seamlessly into our space and the audio quality is quite astounding. It is so clear from the front of the venue to the back, without sounding echoey.”
To mark the completion of the project, staff from JPRO and Alpha Sound were invited to a special dedication ceremony hosted by the church. The event offered clergy, congregation and the wider community a chance to experience the new system firsthand and to acknowledge the technical precision and care invested in the project.
The completed installation at St Matthew-in-the-City demonstrates how the advanced loudspeaker technology in JBL Intellivox can meet the complex demands of heritage spaces. With careful system design and integration, the church has gained a high-quality audio solution that supports its dual role as a place of worship and a community venue—without compromising its architectural character.
