Ahead of the match, DSPPA completed a comprehensive upgrade of the venue’s sound reinforcement system, delivering professional and intelligent audio coverage to ensure clear and stable performance throughout the event.

Large Venue, High Demands
As the home court of the Guangzhou team, Huadu Dongfeng Sports Center features a main arena of over 20,000 square meters with more than 7,000 seats. The large-scale structure and dense audience layout presented significant acoustic challenges:

● Complex reverberation caused by the dome structure and reflective surfaces

● Wide-area coverage requirements across all seating zones

●High system stability demands for continuous sports events

Precision-Zoned Sound Design

To address these challenges, DSPPA conducted on-site analysis and delivered a customized sound reinforcement solution for the venue.

The system adopts a suspended surround line array layout installed along the arena’s ceiling catwalk. Dozens of loudspeaker clusters were deployed, each consisting of line array speakers, subwoofers, and full-range speakers.

How the Acoustic Challenges Were Addressed

This design enables precise zoned coverage across both spectator and competition areas:

●Line array speaker system provides focused coverage for audience seating, minimizing reverberation and improving speech clarity

●Full-range speakers deliver supplementary reinforcement for the court area, ensuring clear announcements for players and officials

●Subwoofers enhance low-frequency impact, creating a more immersive atmosphere during key game moments such as player entrances

The LA1420+LA1420S Line Array Speaker System and D6566 Two-Way Full-Range Speaker used in this project are both certified in the German EASE acoustic simulation database, ensuring reliable system design and accurate acoustic performance prediction.

The line array system combines high-performance passive speakers with powerful subwoofers, delivering clear, penetrating sound, flexible deployment, and reliable audio performance across various applications.

D6563/D6564/D6565/D6566 Professional Two-Way Full-Range Speaker

This Professional Two-Way Full-Range Speaker delivers clear and powerful audio with wide frequency response, making it well-suited for sound reinforcement in large sports venues.

The solution integrates a 32-channel digital mixer, an 8-channel intelligent power sequence controller, true diversity wireless microphones, and audio isolators.

The audio isolators eliminate grounding noise in complex venue power environments, while the wireless microphones ensure stable, interference-free transmission in large-capacity venues. The power sequence controller provides safe system startup and shutdown, preventing equipment damage from power surges. Together, these devices form a stable and intelligent audio control system.

Enhancing Venue Audio Performance

The successful upgrade of Huadu Dongfeng Sports Center demonstrates DSPPA’s continued expertise in large-scale sports venue audio systems.

With the rapid development of sports infrastructure, DSPPA remains committed to delivering advanced audio solutions for stadiums and arenas, supporting high-quality event experiences and the modernization of sports venue systems.
