Located near the Pliska Hotel, east of the city center, Arena Sofia has a 12,000+ capacity, is 16,000m² and is built on five levels, one of which is underground. In addition to the main sports hall, the venue incorporates dressing rooms, training area, fitness center, spa center, restaurant, a press conference hall and underground parking for nearly 1,000 cars.
The system for the main hall of Arena Sofia was designed with Biamp's Community R2, 12-inch, three-way full-range loudspeakers. A total of twenty-four R2-694Z, twelve R2-474Z and four R2-77Z provide coverage for the audience and participant areas. These are supplemented by twelve twin 15-inch, 3,000W program Biamp Community i215LVS subs, which dramatically extend the low frequency power and impact of the system.
