The system consist of two hangs each of 10 Kudo cabinets and four SB28 subwoofers, making this the first church installation in Indonesia to use Kudo with flown subs. 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.
During the installation phase, Tri Tunggal Abadi carried out extensive acoustic treatment to absorb and diffuse two long, parallel reflective walls, which were causing much reverberation in the room. Germain Simon and Cedric Montresor carried out an acoustic simulation using L-Acoustics' Soundvision programme, and advised that Kudo's K-Louver variable directivity should be set at a 50° angle 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.
