Kupittaan Ball Sports Hall

The total area of the hall is 9,500 square metres, with a grandstand capacity of nearly 2,770 people. The main sports hosted include futsal, basketball, handball, volleyball, badminton and gymnastics. The venue also accommodates exhibitions and special events. The space includes three full-sized (22 x 42 m) courts, which can be divided by soundproof curtains.

Designed for flexibility and large-scale use

Audico Systems was responsible for designing and implementing the hall’s sound evacuation and sound reinforcement systems, working in close collaboration with Are Oy, who also acted as the electrical contractor.

‍

"The ball hall is a rare contracting project in Turku, and it was important to have an experienced partner on the project," notes Pekka Suotunen from Are Oy.

‍

The system was built to cover all areas of the venue, including corridors and changing rooms. It mirrors the physical structure of the hall, which can be flexibly divided into one-third or two-thirds sections. The audio system is designed to match this layout, enabling targeted sound control in each space.

‍

At the heart of the system is Audico’s new generation Avec G2 digital audio processing solution, enhanced with Biamp TesiraFORTÉ AI digital DSP technology. This allows for precision fine-tuning and versatile performance across varied event types. Wireless control makes it easy for staff to manage audio in real-time from the field.

Audio access for every user

"The tablet app, wireless mics and RCA outlets across different areas bring the sound system within reach of all users," says Juha Lehmusvuori, venue manager. "Sound can be managed conveniently, either individually for each block or across all three court zones."

‍

Users—whether staff, customers or event organisers—can also connect their own devices to the system via laptop or mobile phone directly from the field level, providing excellent flexibility for different needs.

‍

Acoustic performance meets practical demands

Acoustic design was a key element of the project. Large halls can absorb sound or cause disruptive reverberation. To overcome this, sound quality was carefully simulated, measured and balanced for both music and speech before the system was commissioned.

‍

The solution features RCF P Series loudspeakers and three 18-inch RCF SUB 8004 active subwoofers, providing powerful and even sound throughout the venue. These speakers are also integrated into the exit alarm and safety sound system.

‍

Accessibility needs were addressed using a wireless assistive listening system, chosen due to the structural challenges of installing an induction loop.

‍

"When deploying a system that connects so many devices, a few bugs can occur. These were quickly resolved. Audico’s representatives were also able to explain the system’s standards in a clear and collaborative way," Suotunen adds.
