Kyushu University has completed an audio renovation of Inamori Hall, updating its audio system to improve clarity, balance and coverage for the academic and cultural programs hosted in the 300-square-meter venue.
Located inside the Inamori Foundation Memorial Hall, the space serves as a platform for lectures, symposiums and international exchange, supporting the university’s mission as a globally open academic institution.
After more than a decade of regular use, the hall’s system required a comprehensive update to restore consistent intelligibility. Following on‑site evaluations and demonstrations, the university selected JBL Professional Intellivox DSX280 HD as the primary system for full‑room coverage, with JBL Professional CBT 70J‑1 loudspeakers powered by Crown CDi 2 amplifiers engaged only when the hall is divided.

The installation places JBL Intellivox DSX280 HD powered column loudspeakers on either side of the podium to deliver digitally steerable, uniform speech reinforcement across the full hall. To maintain the interior design, the loudspeaker exteriors were custom finished to blend with the architecture. When the room is partitioned, JBL CBT 70J‑1 column loudspeakers mounted along the side walls are used to provide even coverage within the subdivided configuration, driven by Crown CDi 2 amplifiers for dependable performance.
“The university needed an audio solution that would support clear communication in a room used for lectures and international exchange,” said Nick Screen, VP & GM, Harman Professional Solutions, APAC. “With Intellivox providing primary full‑room coverage and CBT loudspeakers powered by Crown CDi 2 amplifiers serving divided‑room needs, the system delivers consistent intelligibility that keeps audiences engaged.”
Following installation, staff observed immediate improvements in bass response, vocal clarity and detail in high-frequency content. Users noted that sound reached the farthest corners of the room with greater uniformity, creating a more comfortable listening environment for lectures, ceremonies and academic gatherings.
With the new system in place, Inamori Hall is equipped to support ongoing academic, cultural and international programming with reliable intelligibility in both full and divided configurations.. This upgrade, using JBL Professional and Crown solutions, ensures the hall remains a functional and welcoming setting for university events and scholarly exchange.
