Professional Show is the systems integrator for audio/video/lighting systems across Viola Park. After hearing a demo of our systems at the Artemio Franchi Stadium, ACF Fiorentina chose us as the audio partner. Our quality and performance impressed them, especially regarding the size/ performance ratio. We tested The Pinnacle-KR402 II for the main seats. We ensured good coverage with a few column elements and an adequate SP with the portable system. We then developed a fixed-install solution for scalability and discrete visual impact. For the Artemio Franchi Stadium, we proposed the K-array Firenze-KH7 steerable line array element: rethinking the system for the smaller stadium at the Rocco Commisso Viola Park in Bagno a Ripoli, Florence, we needed to adhere to the architectural constraints, leading us to adopt an alternative approach for sound reinforcement. 

We orchestrated the audio system installation in the “Curva Fiesole” stadium alongside Professional Show. The system, featuring seven GS18 subwoofers and 21 KGEAR GH12 speakers for each bleachers, were meticulously positioned to harmonize with the stadium's architectural profile, showcasing a marriage of acoustic technology and design. Drawing from our experience with the K-array Mugello-KH2 I step array configuration and leveraging the KGEAR GA46 amplifiers DSP capability, we designed an unusual loudspeaker reinforcement system that matches the aesthetics of the mini stadium and guarantees an even coverage of the stands with moderately high SPL. The conventional method for installing the loudspeakers in the stadium involves suspending the sound sources down to the coverings and beams. For the Rocco Commisso Viola Park mini stadium, the request was to install an invisible loudspeaker system without a column array or other technical elements breaking the straight lines of the ceiling of the stands coverings. We developed a quasi-horizontal step array of KGEAR GH12 loudspeakers to adhere to the architectural constraints. 

Thanks to their mechanicals, the KGEAR GH12 loudspeakers have been chosen for their high SPL emission and ease of installation. For each of the seven loudspeaker clusters, the three KGEAR GH12 in-step array configurations are evenly distributed under the ceiling so that the meticulous positioning compensates for the covering's up-tilt angle. Each KGEAR GH12 is angled downward with defined tilting angles: for maximising coverage across the listening area, the loudspeaker emissions are aligned with precise delay and equalisation. Each loudspeaker cluster comprises a KGEAR GS18 subwoofer to complete the system frequency response. The sound reinforcement system is designed to provide high SPL for use during football matches for speech and music. 

The Events Pavilion's audio system, comprising our components, was strategically installed to maintain Viola Park's aesthetic standards while delivering superior acoustic quality. The system includes eight Python-KP102 I speakers, two Thunder-KS3P I subwoofers, and eight Rumble-KU212 subwoofers discreetly integrated into the wooden walls. The four two-meter-long Python-KP102 I line arrays are strategically positioned to ensure deep coverage from few source points. The Rumble-KU212 are distributed low-frequency sources used for everyday background music. During events and parties, the Thunder-KS3P I provides engaging low-end high SPL. 

The bars within the "Curva Fiesole" stadium, named "Maglia Viola" and "Il Giglio" feature bespoke audio systems crafted with our expertise. Each bar boasts a combination of four Vyper-KV102R II speakers and eight Rumble-KU26 subwoofers, managed seamlessly through the QSC Audio control system, ensuring optimal sound control for guests. We designed the initial configuration of the “Maglia Viola” and the “Giglio” Bar for moderately high SPL background music and radio commentary of football matches, given the tremendous success of the venues, which can accommodate up to 400 people during very popular events. We also improved the football matches radio commentary with eight Vyper-KV102R II speakers for reinforcement. At this time, four Pinnacle-KR402 II portable systems were added to the resident sound reinforcement system during clubbing nights at “Maglia Viola” and the "Giglio" Bar. 

Viola Park, Fiorentina's new home, is a testament to innovation and dedication to sport and technology. Through strategic partnerships and meticulous design, the integration of cutting-edge audio systems elevates the experience for players, spectators, and visitors alike, ushering in a new era of excellence in sports facilities.
