LightSoundJournal.com: The Kitakami Cultural Exchange Centre, affectionately known as Sakura Hall, is a community hub in the Iwate Prefecture of Japan. Since opening in 2003, its small, medium, and large-sized halls have welcomed performances by national groups and local independent artists. The centre also features rooms for arts and craft workshops, rehearsal rooms for ballet and dance, and a music room for musicians to practice after office hours.

It’s great to learn a bit more about different acoustic systems for different spaces. This is such a large auditorium, and it makes it even harder since they hold events where the audience is distanced from the performers. It seemed like the sound company Bestec Audio did a great job designing it, and Yamaha did a great job installing it. They installed a line array of seven Kara in the center of the space, also adding front fills and SB18 subs for low frequencies. I also read a different article on this same topic, which added that one of the goals of the project was to “recreate the acoustic presence of a larger music hall within a medium-scale space.”
It was interesting to hear that Masahito Oshitani, Head of Stage Technology at Biwako Hall (where this renovation took place) believed line arrays fixed a lot of their sound distribution and directionality issues. They had previously had a point source setup, which is where individual speakers are used as opposed to multiple stacked on top of each other. I’ve heard arguments for use of both types of systems, but generally line arrays are used in larger spaces.
