Martin Audio Delivers Immersive, Weatherised Sound at Tokyo’s New Giants Town Stadium — Bringing Fans Closer to the Action with A Meticulously Engineered Audio Experience Tailored for Professional Sports

Giants Town Stadium in Inagi, Tokyo — the new home of the Yomiuri Giants’ farm team — has been equipped with a Martin Audio-based weatherised sound system designed to immerse fans in every moment of the game. The 2,900-seat, three-storey facility, which also hosts women’s and amateur men’s baseball as well as multi-purpose events, opened in March this year and was created to give audiences a closer, more intimate connection to the sport.

Denon Engineering Co. Ltd oversaw the project’s acoustic planning, construction and sales, deploying a mix of Martin Audio CDD10-WR, CDD6TX-WR, CDD8-WR and ADORN A40 loudspeakers across the venue. The CDD10-WR models serve as the main system, while the CDD6TX-WR units cover premium ‘Excite’ seats, the first and third base infield areas, the rooftop garden, and the right-field standing zones. The CDD8-WR speakers cater to the outfield grass area and are also used as temporary portable units, while ADORN A40 loudspeakers serve the Umpire area inside the field.

The entire system operates via Dante with Symetrix handling processing and distribution, and Netgear providing network switching. Acoustic simulation and system tuning were carried out by Audiobrains to ensure optimal coverage and tonal balance throughout the stadium.

The Martin Audio system was selected for its ability to deliver high clarity, warmth and presence across every seating tier, perfectly matching the demands of professional sports environments. “At G-Town, the emphasis is not simply on ‘producing sound,’ but on providing the optimal acoustic environment for each area and purpose,” stated the Denon Engineering design team. “The type and placement of speakers are carefully adjusted based on how the sound reaches and is heard. Martin Audio CDD10-WR speakers, which deliver clear sound over a wide area, were used as the main speakers. These cabinets are weather-resistant and dust-proof, preventing deterioration and breakdown due to wind, rain and humidity.”

Sound containment was another crucial design challenge. To prevent leakage outside the stadium, all speakers were installed in dedicated enclosures with tightly controlled directionality, ensuring accurate sound projection within the stands while minimising spill beyond the perimeter.

Adding to the immersive experience, the CDD6TX-WR systems elevate the premium ‘Excite’ VIP seating area — positioned closest to the field — delivering dynamic clarity for both announcements and background music. These high-quality speakers enhance the unique viewing experience that defines Giants Town Stadium, creating an emotional bond between the fans and the game.

Given the stadium’s 122-metre span from home plate to centre field, precise delay correction was applied to counteract the 0.36-second lag that naturally occurs across such distances, ensuring consistent, natural sound from every seat. The first-floor loudspeakers also serve as emergency units, ensuring reliability and safety.

To resolve communication challenges between the third-floor sound control room and on-field officials, the team installed microphones on the field, enabling smooth coordination between referees and the PA announcer. Martin Audio ADORN A40 speakers were chosen for their articulate sound reproduction to support this function.

At the system’s core lies an intuitive Symetrix control environment, allowing operators to manage microphones, background music and event audio from tablet interfaces. The user-friendly interface can be customised according to operator proficiency, while a ground-level patch panel provides real-time system monitoring and easy maintenance access.

In a venue where sport and entertainment seamlessly converge, the Giants Town Stadium project demonstrates how precision sound design elevates the emotional impact of live sport. For Denon Engineering, Audiobrains and Martin Audio, it stands as a benchmark in audio excellence — where every cheer, crack of the bat, and crowd roar is delivered with stunning clarity and heart.
