L-Acoustics audio systems have been deployed at the Wat Tha Sung, located in Uthai Thani province of Thailand, to provide the temple with sound. The systems were installed as one of the newer main halls, Sala 12 Rai, underwent extensive renovation in preparation for being renamed 100th Birthday of Pra Rachapromyan. Vision One, a Bangkok based AV company, was tasked to handle the project.
The update included the installation of an L-Acoustics loudspeaker system, comprising a combination of Kara variable curvature line arrays, ARCS Focus constant curvature line sources and coaxial X-Series cabinets.
The main requirement of the hall with regards to audio was clarity as the space is primarily used for chanting, sermons and meditation teaching. It required even SPL coverage of +/- 3dB across its entire area; a challenge made more complicated because its structural design includes a large number of pillars located relatively close together.
In addition to the acoustic challenges, the speaker system also had to be as discreet as possible, in order not to intrude upon the atmosphere of the temple. The final design comprised 48 Kara, eight SB18i, 50 X12, four ARCS Focus and six X8, all powered by 30 LA4X amplifiers.
