Bethany Suko Manunggal church installs L-Acoustics system
Published: WORSHIP
INDONESIA: Tri Tunggal Abadi, L-Acoustics’ Indonesian representative, has installed a Kudo line source system into one of Indonesia’s largest churches, the new 3,000-seat Gerej Bethany Suko Manunggal in Surabaya, Jawa Timur. This is the first church install in the country to use Kudo with flown subs.
The system consists of two hangs each of 10 Kudo cabinets and four SB28 subwoofers. Three 12XT coaxials are used for front fill, with two 112P for the pastor’s monitor system and two 108Ps as stereo keyboard monitors. The system is driven by one LA4 and 12 LA8 amplified controllers.
The main challenge with the project was the amount of reverberation in the room created by the two long, parallel reflective walls. Tri Tunggal Abadi carried out extensive acoustic treatment to absorb and diffuse this. Germain Simon and Cedric Montresor carried out an acoustic simulation using L-Acoustics’ Soundvision program, and advised that Kudo’s K-Louver variable directivity should be set at 50° on the top four boxes and 110° on the bottom six, to avoid reflections from the side wall of the balcony. Members of the congregation have since remarked that even right at the back of the church, the sound was very clear and detailed.
Pastor Aswin Tanuseputra, who heads up the church, has declared himself very pleased with the new sound system, having overseen the construction of the church in just three and a half months. The church opened with a surprise birthday party for his father, Pastor Alex Abraham Tanuseputra, who founded the Bethany Church in Indonesia.
