This video documents the retractable loudspeaker system at the Elbphilharmonie in Hamburg, Germany, offering a close look at how audio equipment is integrated into the architecture of its Grand Hall.

Loudspeakers can be lowered from the central sound reflector above the stage to support amplified sound for the upper seating tiers. With audiences seated around the stage and across multiple levels, the hall presents particular challenges for loudspeaker placement and sound coverage.

Through this field observation, Herwin Gunawan highlights the coordination between architectural design, room acoustics, and sound reinforcement. The retractable arrangement offers a reference for considering how technical equipment can be incorporated into a performance venue while responding to its spatial character and different event requirements.

For architects, acoustic consultants, audiovisual designers, and venue operators, the video invites closer attention to the relationship between equipment visibility, audience layout, and the listening experience.

Part of the Herwin Gunawan Work video library, this observation explores how audio system integration contributes to the design and operation of cultural spaces.
