Meyer Sound Constellation Plays Key Acoustical Role At New Jakarta Theatre

Constellation facilitates customizing the sonic response while 285 self-powered loudspeakers joined by line arrays and more are deployed throughout the 2,500-capacity auditorium.

Opened late last year, the JIExpo Theatre is the new flagship venue of the Indonesian capital city’s Jakarta International Expo (JIExpo) center for meetings, events and arts performances, and it’s outfitted with a Meyer Sound Constallation acoustic system joined by processors and loudspeakers from the company.

Constellation and the complementary direct reinforcement system — based on LEOPARD line array loudspeakers — were provided through Meyer Sound national distributor Mega Swara and installed in the 2,500-capacity theatre by Jakarta-based integrator Kairos Multi Jaya.

Jakarta International Expo is a private enterprise, owned by the Murdaya family, and from the outset the theatre’s managing director, Prajna Murdaya, was committed to achieving excellence in all technical aspects of the project, including audio and acoustics. “The venue was originally specified to be just a theatre, but I saw the potential to make it also serve as Indonesia’s largest concert hall,” says Murdaya. “When I heard about Constellation and its worldwide base of existing high-profile installations, that became a key factor in deciding to go ahead and offer it here as well.”

Prior to his final decision, Murdaya auditioned a Constellation system at the Singapore International School. “I was floored by the drastic difference it made, both onstage and in the audience,” he states. “A music teacher was singing an art song, starting with Constellation on. They turned it off in the middle, and her face showed bewilderment. The effect was dramatic — and hilarious.”

Among the venue’s first events was a concert by cellist Yo-Yo Ma, with the Constellation system remaining on throughout the performance, extending the theatre’s RT60 baseline physical acoustic from 1.2 seconds to 2.2 seconds to add reverberant depth. The flexibility of Constellation allowed the theatre’s technical manager, Bayu Wicaksana, to customize the response, specifically optimizing for the renowned cellist’s instrument.

A total of 285 small, self-powered loudspeakers (MM-4XP miniature and UP‑4XP full range plus UMS-1XP subwoofers) are deployed throughout the auditorium, intended to create natural acoustical environments uniformly throughout the large space. The processing is handled by Meyer Sound’s multi-module D-Mitri Digital Audio Platform, with 51 microphones distributed overhead for sensing the ambient acoustics.

For events requiring amplification, the JIExpo Theatre provides a direct reinforcement system anchored by LEOPARD line arrays, with arrays of 12 loudspeakers per side to cover the first two levels and an additional set of four per side for the uppermost level. Controlled bass is supplied by a cardioid configuration of five 1100-LFC low-frequency control elements flown over center stage. Center channel loudspeakers are UPQ-1P, with UPJ-1P™ loudspeakers as side fills and UPM-1P loudspeakers for front fills as well as under- and over-balcony fills. The system can be used with Constellation off, or with subtle acoustical enhancements added for a variety of pop, rock, jazz and musical theatre performances.

“Using Constellation lets us ‘wrap’ the PA sound into the room for the best effect,” notes Wicaksana. “Working together, these two systems are setting a new and higher standard for theatres and performing arts centres in Indonesia.”

Although open for only a few months before events were suspended by the pandemic. Murdaya attributes the early success in part to the venue’s innovative application of the newest sound technologies. “The Meyer Sound team was very responsive in meeting our requests,” he says. “Their team was great to work with, and I could tell they have a passion for taking on very innovative projects. Vendors usually balk at unusual requests, but Meyer seems to get excited by them.”

Other key contributors in the design phase were theatre consultants Philip Soden and WSDG acoustic consultants. The Meyer Sound contingent was led by Constellation project director John Pellowe with design and tuning of the direct reinforcement system supervised by director of system optimization Bob McCarthy.

JIExpo Theatre offers one of the largest stages in Asia, measuring 48 meters wide by 16 meters deep and expanding up to 21 meters deep following renovations with the orchestra pit covered. The theatre is the latest addition to the larger exposition complex, first opened in 2010. JIExpo also offers 100,000 square meters of exhibition and convention space, incorporating five exhibition halls along with ballrooms, meeting rooms and support operations.
