Chandler Theatre Upgrades With JBL VTX A6 System

The Chandler Theatre, originally constructed for the 1982 Commonwealth Games, has long served as one of Brisbane’s most versatile performance spaces. With its original loudspeaker system reaching the end of life, the 1,500-seat venue required a modern upgrade capable of handling a wide range of programming, from school productions and orchestral concerts to national touring acts.

After a competitive design process, a new sound system based on JBL Professional’s VTX A6 subcompact line array was installed by High Noon Stage Productions, with system consultation by XConnect Professional Services and support from Australian distributor MadisonAV. The result is a powerful yet discreet audio solution tha t balances performance with architectural and operational requirements.

The final design features three hangs of eight JBL VTX A6 loudspeakers supported by three hangs of three VTX B15 subwoofers in cardioid configuration, powered by Crown I-Tech HD 4x3500W amplifiers. JBL Venue Synthesis software played a key role in system design, providing accurate modeling of coverage, drop heights, and load distribution. The compact form factor of the A6 and B15 systems proved essential in maintaining sightlines, reducing rigging weight, and fitting within the theatre’s cantilevered truss system.

“The VTX A6 subcompact system allowed us to keep the hang height short enough to avoid blocking sightlines, keep weight down, while still delivering the required SPL,” said Glenn Thompson of XConnect. “The Venue Synthesis predictions proved remarkably accurate – the first hang went up exactly as modeled and didn’t require any adjustment.”

With the upgrade complete, the Chandler Theatre now benefits from a rider-friendly system that has already impressed visiting engineers and performers. “Thanks to our new state-of-the-art JBL loudspeaker system, the venue can now attract new, fresh content while retaining the diverse programming we already host month to month,” said Alex Hutchison, General Manager of the Sleeman Sports Complex. “We’re genuinely excited about what lies ahead.”

By combining the precision of JBL VTX loudspeakers with Crown amplification and expert local support, the Chandler Theatre has achieved a solution that honors the venue’s history while equipping it for the demands of contemporary productions.
