At-Thohir Mosque maintains grandeur with L-Acoustics


Located on the perimeter of the Podomoro Golf Complex in a leafy suburb of Jakarta, At-Thohir Mosque was built by the extended family of automotive businessman, Teddy Thohir. This pearlescent house of worship features 29 domes, and can welcome up to 1,900 worshippers, having been inaugurated by Indonesia’s president this spring.

The mosque’s technical committee required a powerful and pristine sound system that would be discreet against the building’s clean white interior adorned with gold religious calligraphy. Recent government guidelines put a cap on sound volumes at 100 decibels and limited amplified audio to inside buildings, which made the sound system choice a little trickier. At-Thohir Mosque turned to Jakarta-based pro audio supplier, Gracia Auvindo, for help.

Hendra Halim, project manager and systems engineer at Gracia Auvindo, explained that in addition to the aesthetic and SPL requirement, installation options were limited in the 28.5m x 28.5m main prayer hall. Halim said: “In addition, the hall is constructed of marble and granite, creating reflective surfaces throughout, compounded by the inner side of a dome-shaped roof.”

Halim worked with L-Acoustics application project engineer APAC, Chung Wah Khiew, using L-Acoustics Soundvision to design a system that would minimise reflections by keeping sound on the audience area, avoiding the domed roof and reflective walls. “We mapped a Syva design in Soundvision and found that its 50m throw capacity would be more than sufficient for the 30m-deep prayer hall,” he explained. The graceful lines of Syva would also melt into the architecture, so Halim brought the design proposal to the mosque committee, noting that the system would be white to match the venue.

The final system design installed in the main prayer hall consists of two Syva placed 4m high and serving as the main system. Four 5XT coaxial speakers serve as front-fill, while an X8 serves as centre-fill. Two additional Syva, mounted at 3.5m, serve as delay speakers. “The two Syva delays allow the mosque to avoid driving the main Syva at full power, thereby reducing reflections,” added Khiew.

Four additional 5XT coaxial speakers are installed in the antechamber, while two further 5XT are installed in the mosque’s basement, both of which are used for celebratory functions.

With the new sound system calibrated, the mosque committee is said to be pleased with its excellent intelligibility. More so, congregation members have commented on the clarity of the prayer services. “Working as a team with L-Acoustics and the At-Thohir committee, we’ve succeeded in overcoming important challenges to getting great sound in this space,” Halim said. “Soundvision was especially helpful in ensuring that our team proposed and installed the ideal system, and the satisfaction of the committee and the congregation are a great honour for the Gracia Auvindo team and me,” he concluded.
